Crab Walk
triceps
What moves the load, and what it costs
4.3MET
Triceps is the prime mover, with the glutes, abs, hamstrings assisting. Loads the triceps and posterior shoulder in a position nothing else in a normal programme reaches.
Cue: Sit with the hands behind you and the feet in front, lift the hips and walk forwards or backwards.

SHARED AXIS · SEVEN VALUES FROM ONE TABLE · HIGHLIGHTED ROW IS THIS MOVEMENT
The compendium files crab walk under a category, not a lift. Read the ladder as position, not precision: this is heavier work than sitting quietly by a factor of 4.3, and middling for conditioning work.
Turning that MET value into a real energy cost
- Map the movement to a published category. The compendium measures categories of conditioning work, never individual lifts, so crab walk is filed under Circuit training, moderate effort.
- Take the category's MET value — 4.3. One MET is the cost of sitting quietly, so this is 4.3 times resting metabolism.
- Multiply by 3.5 to get millilitres of oxygen per kilogram per minute, the unit the MET is actually defined in.
- Multiply by your bodyweight in kilograms and divide by 200. The result is kilocalories per minute of work.
- Count working minutes only. Under load, not under the roof — a set of eight is about 25 seconds of the hour you were there.
kcal/min = MET × 3.5 × body mass (kg) ÷ 200 Crab Walk: 4.3 × 3.5 × 70 ÷ 200 = 5.27 kcal/min

What is actually doing the work
| Muscle | Role | What it does here |
|---|---|---|
| TricepsTriceps brachii | Prime mover | Straightens the elbow. The long head also crosses the shoulder, so it is stretched and loaded hardest with the arm overhead. |
| Glutesਗਲੂਟੀਅਸ ਮੈਕਸਿਮਸ, ਮੀਡੀਅਸ ਅਤੇ ਮਿਨਿਮਸ | Synergist / stabiliser | ਕੁੱਲ੍ਹੇ ਨੂੰ ਖੋਲ੍ਹਦਾ ਹੈ (ਮੈਕਸਿਮਸ), ਅਤੇ ਇਸਨੂੰ ਬਾਹਰ ਵੱਲ ਲਿਜਾਂਦਾ ਤੇ ਸਥਿਰ ਰੱਖਦਾ ਹੈ (ਮੀਡੀਅਸ ਅਤੇ ਮਿਨਿਮਸ)। ਸਰੀਰ ਦਾ ਸਭ ਤੋਂ ਤਾਕਤਵਰ ਇਕੱਲਾ ਪੱਠਾ ਸਮੂਹ। |
| Absਰੈਕਟਸ ਐਬਡੋਮਿਨਿਸ | Synergist / stabiliser | ਧੜ ਨੂੰ ਅੱਗੇ ਝੁਕਾਉਂਦਾ ਹੈ ਅਤੇ, ਇਸ ਤੋਂ ਵੱਧ ਕੰਮ ਦੀ ਗੱਲ, ਇਸਨੂੰ ਪਿੱਛੇ ਵੱਲ ਖਿੱਚੇ ਜਾਣ ਦਾ ਵਿਰੋਧ ਕਰਦਾ ਹੈ। ਕਰੰਚ ਅਤੇ ਪਲੈਂਕ ਦੋਵੇਂ ਇਸ ਉੱਤੇ ਭਾਰ ਪਾਉਂਦੇ ਹਨ — ਵੱਖ-ਵੱਖ ਢੰਗ ਨਾਲ। |
| HamstringsBiceps femoris, semitendinosus, semimembranosus | Synergist / stabiliser | Bends the knee and extends the hip. Because they cross both joints, they need both a hinge (hip) and a curl (knee) to be trained fully. |
The prime mover produces the movement against the resistance; synergists assist and stabilisers hold a joint still without moving it. An exercise trains the whole muscle it loads — there is no way to work only part of a muscle, and no exercise removes fat from the area around it.
Set up, then earn the rep
Bodyweight. Every rep should look like the first one. The moment it stops looking like the first one, the set is finished.
PATTERN · CARRY
- Start on hands and knees with the hands under the shoulders and the knees under the hips.
- Lift the knees about an inch off the floor and hold that hover.
- Sit with the hands behind you and the feet in front, lift the hips and walk forwards or backwards.
- Move the opposite hand and foot together in small steps, keeping the hips low and level.
- Keep the head neutral and look just in front of your hands.
- Travel for distance or time rather than counting reps.
Where this one breaks down
Not theory. These are the faults you correct on a gym floor, and the correction that actually works.
Hips swaying side to side.
Take smaller steps until the hips stay quiet.
Knees too high.
An inch off the floor. Any higher and it becomes a hip-flexor exercise.
Rushing.
Slow crawling is far harder and far more useful.
Regress it, or progress it
Regress — earn it first
Nothing on this site regresses it further: this is already near the entry point of its pattern. Take load off, shorten the range, or slow the tempo — in that order.
Progress — the next demand
This sits at the top of its progression here. Add load, add range, slow the tempo or go single-limb before you go looking for a new exercise.
Prescription: load, reps, rest
Read off the goal, then hold the technique constant as the load climbs. Derived from the movement's mechanics, not invented for this page: a compound lift loads several joints, so it tolerates heavy loads and needs long rests.
| Goal | Sets | Reps | Rest | Notes |
|---|---|---|---|---|
| Strength | 3–5 | 3–6 | 3–5 min | Heavy loads need long rests. Cutting rest to two minutes turns a strength set into a conditioning set. |
| Muscle size | 3–4 | 6–12 | 90–180 sec | Take most sets to within one to three reps of failure. Total weekly hard sets per muscle matters more than the exact rep number. |
| Endurance / fat loss | 2–4 | 12–20 | 45–75 sec | Lighter loads and shorter rests. Fat loss is decided by the diet; this preserves muscle while it happens. |
| First month | 2–3 | 8–10 | 2 ਮਿੰਟ | Well short of failure, same weight every set, until the movement looks the same on the last rep as the first. |
Time under load, in kilocalories
Read these as minutes of work, not minutes in the building. A set of eight takes about twenty-five seconds; the rest of the hour is rest, chalk and queueing.
Mapped category: Circuit training, moderate effort — 4.3 MET. That is the published category this movement is filed under, not a measurement of this specific lift.
Worked at 4.3 MET × 3.5 × 70 kg ÷ 200 = 5.27 kcal per working minute for a 70 kg adult. Scale it by your own bodyweight; the equation is linear. The full activity dataset lives at BurnLab.

Nothing here trains the same prime mover through the same pattern. Swap the pattern rather than the muscle, and accept the session will look different.

The questions that come up on the floor
What muscles does the crab walk work?
Crab Walk is a compound movement in which the triceps is the prime mover, assisted by the glutes, abs, hamstrings. Straightens the elbow. The long head also crosses the shoulder, so it is stretched and loaded hardest with the arm overhead.
Is the crab walk good for beginners?
ਹਾਂ। ਇਸ ਸਾਈਟ ਉੱਤੇ ਤਕਨੀਕੀ ਔਖਿਆਈ ਵਿੱਚ ਇਸਨੂੰ 5 ਵਿੱਚੋਂ 2 ਦਰਜਾ ਮਿਲਿਆ ਹੈ — ਇੱਕ ਜਾਂ ਦੋ ਸੈਸ਼ਨਾਂ ਵਿੱਚ ਸਿੱਖਣਯੋਗ; ਗ਼ਲਤ ਹੋ ਜਾਵੇ ਤਾਂ ਸੱਟ ਦਾ ਖ਼ਤਰਾ ਘੱਟ। ਸਭ ਤੋਂ ਹਲਕੇ ਸਮਝਦਾਰ ਭਾਰ ਅਤੇ 8–10 ਦੇ ਦੋ ਜਾਂ ਤਿੰਨ ਸੈੱਟਾਂ ਨਾਲ ਸ਼ੁਰੂ ਕਰੋ।
What can I do instead of the crab walk at home?
Nothing is needed — the crab walk already requires no equipment at all, which is why it belongs in any home programme.
How many sets and reps of the crab walk should I do?
For muscle size, 3–4 sets of 6–12 with 90–180 sec rest. For strength, 3–5 sets of 3–6 with 3–5 min rest. In your first month, 2–3 sets of 8–10, stopping well short of failure. Total weekly hard sets per muscle group matters more than the exact rep number in any of these ranges.
Does the crab walk burn fat from the triceps?
No. No exercise removes fat from the area it trains — spot reduction has been tested repeatedly and does not happen. Training the triceps builds the muscle underneath; where body fat is lost from is decided by an overall calorie deficit and by your genetics, not by which exercise you chose.
Muscle roles follow standard kinesiology references and are described by joint action rather than by gym convention — see how this site is built. Energy figures are derived from the 2024 Adult Compendium of Physical Activities. Every reference is named and dated on the sources page. General information only — not medical or coaching advice. Load, form and progression should be adjusted to your own experience and any injury history. When in doubt, get coached in person.
