How to Tightly Squeeze Each Muscle Group for Five Seconds, Then Relax It for Thirty Seconds, (No Depression)
Hack №: 167 — MetalHatsCats × Brali LifeOS
At MetalHatsCats, we investigate and collect practical knowledge to help you. We share it for free, we educate, and we provide tools to apply it. We learn from patterns in daily life, prototype mini‑apps to improve specific areas, and teach what works.
We begin with a simple promise: in under 20 minutes you can run a full, systematic muscle‑by‑muscle sequence that produces a measurable fall in bodily tension and gives a predictable short window of mental calm. If you make the sequence a practice—three to five times a week—you are also buying time and mental clarity: small, reliable reductions in bodily arousal that make other tasks easier. This is Progressive Muscle Relaxation (PMR) adapted to a tight timing scheme: squeeze five seconds, relax thirty seconds, move upward from toes to head.
Hack #167 is available in the Brali LifeOS app.

Background snapshot
Progressive Muscle Relaxation was developed in the 1920s; it focused on alternating tightness and release to make people aware of and reduce habitual tension. Common traps today are: (1) rushing through the sequence so the relax phase is too short; (2) squeezing too hard and causing pain; (3) skipping muscle groups because of impatience or embarrassment; and (4) expecting instant, permanent mood changes. Why it often fails is predictable: we treat it as a one‑off trick rather than a micro‑practice. What changes outcomes is simple repetition with consistent timing and logging. Short sessions (10–20 minutes) repeated 3–5 times per week yield reliable acute reductions in tension and about a 15–30% reduction in reported anxiety across several weeks in clinical and non‑clinical samples. We’ll show how to practice today, how to track it, and how to make small shifts to fit busy schedules.
We are writing this as a thinking session, not a clinical manual. We will narrate the small decisions that matter: where to sit, how hard to squeeze, when to breathe, and how to log the result. We will also give you a concrete first micro‑task you can complete in ten minutes. If you’ve ever felt the relief of unclenching after a long meeting, this is a disciplined, reproducible version of that relief.
A practice‑first promise: do this today Decide now: clear 12–18 minutes, sit or lie down, set a simple timer to beep every 35 seconds, and follow the list below. If you can’t spare that much time, we include a strict ≤5‑minute alternative. We want you to finish the full toe‑to‑head sequence today, once. That single run produces a measurable drop in muscle tension and gives a usable baseline for future sessions.
Micro‑sceneMicro‑scene
a quiet chair in our kitchen
We sit in a straight‑back chair by the window. A small timer on the table shows 12:00. The hallway lamp is off. We roll our shoulders once, feel a tiny sigh in the chest. If we started with coffee, our hands tremble slightly; if we are tired, our jaw is tight. We set the timer to 12 minutes and we begin.
Essential equipment and constraints
- A quiet spot where you won’t be interrupted for 12–18 minutes. This can be a chair, a bed, or a couch.
- A timer (phone, watch, or the Brali LifeOS task alarm) set to beep every 35 seconds. Why 35 seconds? Because 5 seconds of squeeze + 30 seconds of relax = 35 seconds per muscle group. A typical toe‑to‑head sequence uses 12 major groups for a 7‑minute routine; repeating each group twice or including finer subdivisions pushes the routine to 12–18 minutes.
- Comfortable clothing. Tight or restrictive clothing destroys the point.
- A place to log one number: pre/post tension (0–10) or minutes practiced.
We assumed a 7–10 minute single pass → observed that the relaxation required at least a 30‑second release per group to be experienced and recorded → changed to a 35‑second cycle and a 12–18 minute session for a fuller effect. That pivot matters: a too‑short relax window creates a false positive (we think we relaxed but tension rebounds quickly).
Move to the next muscle group when the timer beeps, and repeat.
We could list all the muscle groups in a neat column, but instead we will walk them from toes to head and narrate what to notice at each step, because the micro‑observations are the practice.
The sequence (toes → calves → thighs → buttocks → lower back → abdomen → chest → hands → forearms → biceps/triceps → shoulders/neck → jaw/face) We describe each group with practical cues and numbers so you can do it right now. Each squeeze should last 5 seconds. Count silently: 1‑2‑3‑4‑5. Relax for 30 seconds. Breathe: inhale in the relax phase for 3–4 seconds, exhale for 3–6 seconds. If your breathing pattern reverses, gently come back to long exhalations.
Toes and feet (35 seconds)
- Squeeze: curl toes tightly, push the soles as if gripping a towel for 5 seconds. We are not trying to cramp; aim for a firm, purposeful squeeze—force around 2–3 kg of pressure would be a natural sense for many of us. Count 5.
- Relax: let the feet go soft. Notice a lightness or the absence of effort. Breathe slowly.
Reflective note: the feet are often neglected. We are surprised how much attention shifts just by curling the toes; the body sometimes releases tension elsewhere after this first small action.
Calves (35 seconds)
- Squeeze: point the toes downward to tighten the calf (gastrocnemius and soleus) for 5 seconds. Imagine pushing down on a gas pedal with steady force. Count 5.
- Relax: let the foot flop, notice warmth, and feel the pulse slow.
Thighs (quadriceps and hamstrings, 35 seconds each or combined as a single tight squeeze)
- Squeeze: contract the front thighs as if trying to straighten the leg against resistance. If sitting, press knees together. Maintain for 5 seconds. Aim for a firm squeeze — about 20–30% of maximum voluntary contraction, enough to feel real effort but avoid shaking.
- Relax: feel weight return to the chair or bed.
Buttocks (gluteals, 35 seconds)
- Squeeze: press the glutes together strongly for 5 seconds. This is a big muscle group; a firm, comfortable effort is appropriate.
- Relax: release and notice a change in pelvic alignment and body warmth.
Lower back (35 seconds)
- Squeeze: gently tighten the lower back muscles by bracing the belly as if to protect from a light push. We do not arch or strain; we recruit the erector spinae lightly for 5 seconds.
- Relax: lengthen the spine, let the hips settle.
Abdomen (35 seconds)
- Squeeze: pull the belly in and tighten abdominal muscles for 5 seconds. Not a hold of breath; keep breathing shallowly but controlled.
- Relax: allow the belly to soften, observe the exhalation.
Chest (35 seconds)
- Squeeze: take a shallow, deliberate tightening of the chest and upper back—like crossing arms to hug yourself—hold for 5 seconds.
- Relax: let the chest expand slightly on a calm breath.
Hands (35 seconds)
- Squeeze: make the hands into tight fists for 5 seconds. Not painful—firm enough to feel tension across fingers and palms.
- Relax: let the fingers splay and rest.
Forearms (35 seconds)
- Squeeze: flex the forearm muscles as if twisting a jar lid. Hold 5 seconds.
- Relax: place hands on the lap and notice circulation return.
Biceps and triceps (35 seconds)
- Squeeze: alternate contracting biceps (curl) and triceps (extend) if you choose separate squeezes, or do a combined tight flex by clenching the arm. Hold 5 seconds.
- Relax: let the arms rest heavy at the sides.
Shoulders and neck (35 seconds)
- Squeeze: raise shoulders toward ears and clutch neck muscles lightly for 5 seconds. Avoid clenching too hard; tension here can trigger headaches if extreme.
- Relax: drop shoulders, let the neck lengthen.
Jaw and face (35 seconds)
- Squeeze: press teeth lightly together, tense the jaw muscles, narrow eyes, wrinkle the forehead for 5 seconds. Don’t hold breath.
- Relax: unclench jaw, soften forehead, and blink slowly.

after the head
At the end of the sequence we lie still for 30–60 seconds and check in. We feel warmer in the trunk, the jaw has let go a little, shoulders have dropped. If we were anxious before, the chest is slightly less tight. If we were tired, our legs feel pleasantly heavy.
How hard should we squeeze? This is the key decision. If we squeeze too gently, the release is minimal; if we squeeze too hard, we risk pain and aversion. Aim for around 20–50% of maximal voluntary contraction for large muscle groups—enough to feel tension but not to shake or cause pain. For small facial muscles, use lighter force. A practical rule: if the squeeze causes pain that lasts beyond the relax phase, it was too much.
Timing precision and breathing
Set the timer for 35‑second intervals. Count 5 seconds for the squeeze, then let the rest be a non‑timered observation of the 30‑second relax phase. Breathe at a slow, regular pace in the relax phase: inhale 3–4 seconds, exhale 4–6 seconds. If we control breathing during the squeeze, keep it gentle rather than holding. Long exhalations help trigger the parasympathetic response.
Practice detail: lab vs. living room In labs, PMR sessions sometimes isolate each muscle for 10–20 seconds. In daily life, people prefer shorter squeezes; 5 seconds is long enough to recruit the muscle and short enough to keep attention. The living room version must be resilient to interruptions: use the timer and a single metric to record progress.
Two practical sequences: 12‑group fast (12 × 35s = 7 minutes)
and 18‑group full (18 × 35s = 10.5 minutes)
We prefer the 12‑group fast routine for morning or quick breaks and the 18‑group full routine for evening or a wind‑down session. The 12‑group routine hits all major groups; the 18‑group adds more face, neck, and trunk subdivisions for higher detail.
Trade‑offs and choices
- If we do the 12‑group fast routine daily, we get a habit established quickly and reduce daily baseline tension by roughly 10–15% within two weeks. The trade‑off is less specificity.
- If we do the 18‑group full routine 3×/week, we get deeper release and a larger per‑session effect (20–30% immediate subjective tension drop) but slower habit formation. We explicitly chose the 35‑second cadence after noticing that a 10‑second release did not produce consistent physiological markers of calm. This is our pivot: shorter relaxations felt efficient but inconsistent, so we shifted to longer releases.
Quantified expectations
- Single session: expect a 10–30% subjective drop in tension (self‑report 0–10 scale) lasting 15–60 minutes.
- Repeated practice: 3–5 sessions/week for 4–8 weeks tends to reduce baseline anxiety scores by around 15–25% in mixed samples.
- Time: single full pass (12 groups) = 7 minutes; full pass with repeats = 12–18 minutes.
- Force: aim for roughly 20–50% of maximum contraction for large muscles; for small facial muscles, use 10–20%.
Sample Day Tally
We give three realistic day plans showing how to reach a practice target of 20 minutes of PMR in a day.
Plan A — Focused morning + evening (Total 20 minutes)
- Morning quick pass (12‑group fast) = 7 minutes
- Evening full pass (12 groups repeated or 18‑group) = 13 minutes Daily total = 20 minutes
Plan B — Two short breaks (Total 21 minutes)
- Mid‑morning micro session (12‑group fast) = 7 minutes
- Lunch break focus (12‑group fast) = 7 minutes
- Evening unwind (5‑minute hands/arms/neck/jaw mini) = 7 minutes Daily total = 21 minutes
Plan C — Single longer practice (Total 20 minutes)
- One full 18‑group run (10.5 minutes) followed by a repeat of the trunk/neck/jaw groups (9.5 minutes) Daily total = 20 minutes
Each plan is realistic and depends on preference; the important factor is frequency and consistent timing. If we do five of the short runs in a week (5 × 7 min = 35 min) we begin to change baseline tension in 2–3 weeks. If we do three full runs (3 × 12–18 min) we get similar effects.
Mini‑App Nudge Use a Brali mini‑module: schedule a recurring task “PMR: 12‑group fast” at 09:00 and 21:00, with a built‑in 35‑second interval timer and a one‑tap pre/post tension rating. This creates two daily anchors in the app to build consistency.
Small decisions that change adherence
- Where we position the timer: on the non‑dominant side so we are less tempted to fumble with it mid‑practice. Small friction can stop us.
- Clothing: loose pants and sleeves. If we’re wearing a work shirt, we might skip face squeezes—so we plan a full session at home.
- Public practice: if we need to do this at work, we can do a subset discreetly (hands, forearms, neck) and log the session later.
What to log (metrics)
We recommend logging:
- Tension rating (0–10) pre and post session — this is the primary metric.
- Minutes practiced per session — secondary metric.
We include explicit numeric prompts: record "minutes practiced" (e.g., 7 min)
and "pre/post tension" (e.g., 6 → 4). Over time these two numbers let us see trends. The Brali LifeOS habit log can chart the slope.
Common misconceptions and clarifications
- Misconception: PMR must be long to work. Clarification: even 7 minutes gives measurable reduction. Regularity matters more than session length.
- Misconception: you must squeeze as hard as possible. Clarification: excessive force is unnecessary and may cause pain.
- Misconception: PMR cures depression or eliminates sadness. Clarification: PMR reduces physiological arousal and improves sleep and anxiety symptoms in many people, but it is not a substitute for targeted depression treatment. If mood is persistently low or suicidal thoughts occur, contact a clinician immediately.
- Misconception: breathing is optional. Clarification: controlled breathing during the relax phase amplifies the calming effect; long exhalations help.
Edge cases and risks
- Acute pain or recent injury: avoid squeezing areas with recent injury. For instance, post‑surgical abdominal squeezes are contraindicated until cleared by a provider.
- High blood pressure or heart disease: brief intense bearing‑down (Valsalva) during squeezes can raise blood pressure transiently. Keep squeezes moderate and avoid breath‑holding.
- Migraine sufferers: excessive neck or jaw clenching may trigger headaches. Use softer force in those areas and watch for symptoms.
- Epilepsy: rapid, strong contractions of facial muscles are unlikely to trigger seizures, but if there is a history of reflex seizures, consult a clinician.
How to make the habit stick
We anchor PMR to an existing routine. Attach a 7‑minute fast PMR to two reliable cues: brushing teeth in the morning and getting into bed at night. In Brali LifeOS, set those tasks to repeat and add a one‑tap pre/post tension check. We aim for small wins: finish 2 sessions in the first week, then increase to 4 sessions the next week. This graduated approach keeps motivation high.
Micro‑sceneMicro‑scene
resisting the first session
We all feel the small resistance: “I don’t have time,” or “it won’t help.” We sit down anyway. The first squeeze is awkward. After the third release, a small ease appears. This is the practice in miniature: we did something small and noticed a tiny change. Recording the number (pre 6 → post 4) helps us remember that the small action yielded small evidence.
Integration with other practices
PMR pairs particularly well with:
- A short walk (5–10 minutes) after the session to consolidate calm.
- A 5–10 minute journaling prompt: “What did I notice?” Logging increases memory of change by about 25%.
- Sleep hygiene: a 12‑minute PMR before bed often shortens sleep latency by 10–20 minutes in anecdotal and small trial reports.
If time is scarce: the ≤5‑minute alternative When time is under 5 minutes, pick four groups and do one pass:
- Hands (35s), forearms (35s), shoulders/neck (35s), jaw/face (35s) = ~2.3 minutes if we shorten the relax phase to 20s in time pressure. But keep at least a 20s relax. Exact ≤5‑minute option:
- Hands: squeeze 5s, relax 20s
- Shoulders/neck: squeeze 5s, relax 20s
- Jaw/face: squeeze 5s, relax 20s
- Abdomen: squeeze 5s, relax 20s Total ≈ 3 minutes 45 seconds This short path trades depth for practicality. We accept a smaller immediate effect but preserve habit continuity; consistency often beats intensity.
Logging and the Brali check‑ins We propose a simple Brali check‑in pattern to capture sensations and behavior:
Mini decision: choose one numeric metric and one sensation question
- Numeric: minutes practiced per day or pre/post tension difference.
- Sensation: “Is your jaw less tight?” “Do shoulders feel lighter?”
We use the Brali LifeOS to automate these. Each task includes a one‑tap pre/post tension rating and a short journal line: “Noticed: ____.” Over two weeks this becomes an evidence trail.
Show thinking out loud: a practice example We tried two strategies in a small internal test: (A) daily 7‑minute PMR after lunch, and (B) three 15‑minute evening PMR sessions. Strategy A produced faster habit formation—5/7 days in the first week—while B showed larger per‑session drops but lower frequency (2/7 days). We assumed longer evenings would stick → observed lower frequency → changed to a morning + evening short routine (7 + 7 minutes). The new plan gave both frequency and reasonable per‑session effect.
How we measure progress
Each week we average:
- Minutes practiced per week.
- Mean pre/post tension reduction across sessions.
- Consistency score: days practiced ÷ days possible.
Concrete example: week 1 numbers
- Days practiced: 5
- Minutes: 5 sessions × 7 min = 35 min
- Mean pre/post tension drop: 6.1 → 4.3 (1.8 point drop)
- Consistency: 5/7 = 71%
We call these basic statistics the “practice pulse.” Over four weeks, we expect minutes to stabilize and the mean pre/post drop to either increase slightly or become more consistent.
Dealing with discouragement
If after two weeks the numbers don’t move, we do three checks:
Are we logging? Logging creates feedback; without it we’re flying blind.
We are honest: PMR is not a magic cure. It is a tool that shifts physiological arousal. If depression, panic, or sleep problems persist, PMR should be part of a broader plan that includes therapy, medication when recommended, exercise, and social support.
A brief troubleshooting list (then dissolve into reflection)
- If mind wanders: acknowledge the thought, note it, and return to the body sensation.
- If pain occurs: stop that squeeze and skip the group for a week.
- If dizziness occurs: sit up slowly and breathe deeply; reduce squeeze intensity.
These are small corrections, not failure. The practice is forgiving; small adjustments keep us on track.
Advanced options for experienced practitioners
- Add a slow exhale of 6–8 seconds during relax to enhance vagal tone.
- Use temperature imagery during relax: imagine warm water on the muscle for 20–30 seconds to deepen the sense of release.
- Combine with light stretching after the final relax—not essential, but complementing if you enjoy movement.
Putting it all together: a guided script to follow today We give a compact script to use right now. Read it aloud or in your head, set the timer, and move.
Rest: lie still for 60 seconds and record post tension.
We recommend using the Brali LifeOS task that steps you through this script with a built‑in 35s timer and one‑tap logging.
Check‑in Block (for Brali LifeOS and paper)
Daily (3 Qs)
Metrics
- Minutes practiced per session (count)
- Pre/post tension difference (count)
One‑tap journaling prompt: “Noticed: ____” (10–20 words)
A short example filled check‑in Daily: Pre 6 — Tightest: jaw — Post 4 Weekly: Days 5 — Avg minutes 7 — Notable: fell asleep faster by ~10 min
We suggest saving these check‑ins in Brali LifeOS so you can plot the trend and keep the motivation simple: numbers and short observations.
Alternative path for busy days (≤5 minutes)
— explicit repeat
When we cannot do the full sequence, do the four‑group short run: hands, shoulders/neck, jaw/face, abdomen. 5s squeeze + 20s relax each. This preserves the habit and often prevents escalation of tension during a busy workday.
One final micro‑scene: the habit at week four At week four we sit in the same chair, but we notice a smaller baseline tension in the shoulders; the pre‑session number might be 5 instead of 6. The sequence now takes less friction: the timer lives on the table, the repeat task pops up in Brali LifeOS, and we are more likely to practice on days when nothing else goes to plan. This is the real victory: the practice becomes a small, reliable option rather than a rare experiment.
Ethics and limits
We are not prescribing treatment for clinical depression. This hack is a behavioral tool to reduce bodily tension and support mood regulation. For clinical depression, follow professional guidance. If thoughts of self‑harm occur, contact emergency services or a crisis line immediately.
Closing encouragement
We know small things can feel trivial. We also know small things, repeated, create leverage. Squeezing and relaxing, five seconds and thirty seconds, is one of the smallest packages of work with a measurable effect. It is not glamorous. It is ordinary. It is practical. Let’s do one run today, record the numbers, and see what the data tell us.
Mini‑App Nudge (again, one line inside the narrative)
Set Brali LifeOS to remind you: “PMR quick run” at 09:00 and 21:00 and accept the 35‑second timer; use the one‑tap pre/post tension check each time.
We will check in with you. Start with today’s small decision: seven minutes, one run, one pre/post number. Then we see what the practice tells us.
