The verdict
Spider Crawl has 3-step instructions, documented with fewer steps than most of the 93 abdominals exercises PlainExercise catalogues.

Source Free Exercise DB · 2026-07-10
Spider Crawl is documented from the Free Exercise DB (CC0) extract, last ingested July 2026. Classification, muscle roles and instruction text are source facts; the placement and cohort measures on this page are computed by PlainExercise and are not a rating of the movement.
What the Spider Crawl Data Reveals · DOC · PULL/COMPOUND
Spider Crawl stands out on force direction, the first filter on this record.
A short step list is a thin upstream record, so taxonomy badges carry most of the page identity.
Context matters: taxonomy (level, mechanic, force, musculature, equipment) does not account for individual biomechanics, joint history, or recovery. Common-mistake framing below is derived from classification fields, not case-specific coaching. Not medical or personal-training advice. Consult a physician or certified trainer before starting, especially with injuries, cardiovascular conditions, recent surgery, or pregnancy.
Spider Crawl catalog footprint
Among 93 exercises whose primary muscle is abdominals, Spider Crawl ranks #12 by catalogued variation count. The upstream file attaches 2 images to this slug. See the step-count ranking for abdominals for peer documentation depth.
Muscles worked
The Free Exercise DB classifies each muscle as primary or secondary. It does not measure activation, so we show involvement, not percentages.
Source: Free Exercise DB primary/secondary muscle classification. Actual recruitment varies by load and form.
Intensity context
For reference, here is where common activities sit on the MET intensity scale. Spider Crawl does not have a measured MET in the source data, its intensity depends on the load and effort you use. Estimate calories for any activity with the calorie calculator.
MET values from the Compendium of Physical Activities (Ainsworth et al., 2011). A general reference scale, not a rating of this specific movement.
How to do it
- Begin in a prone position on the floor. Support your weight on your hands and toes, with your feet together and your body straight. Your arms should be bent to 90 degrees. This will be your starting position.
- Initiate the movement by raising one foot off of the ground. Externally rotate the leg and bring the knee toward your elbow, as far forward as possible.
- Return this leg to the starting position and repeat on the opposite side.
Common mistakes
- Rushing through reps before the pattern is grooved - at this stage, a slow, controlled tempo (2-3s down, 1-2s up) on Spider Crawl teaches the nervous system the movement far faster than speed does.
- Cutting the range of motion short - moving the abdominals through its full safe range on Spider Crawl is what most reliably separates effective reps from wasted ones.
- Treating a compound lift like an isolation movement - Spider Crawl recruits multiple joints; bracing the core and engaging stabilizers matters as much as the prime movers.
- Shrugging the shoulders up toward the ears on pull movements, keep shoulder blades down and back to load the correct muscles.
- Breathing out of sync with the lift on Spider Crawl - brace and inhale during the lowering phase, exhale on the exertion, especially important with just bodyweight where control matters most.
Who this is for
- People new to resistance training who want to build a foundation in the movement pattern
- People who want to train the Abdominals and secondarily chest, shoulders
- People training at home without equipment
Who this is NOT for
- People hunting equipment swaps, this record has none to offer; browse the peer abdominals exercises for alternate patterns instead.
- Anyone with acute pain in the joints or muscles involved, pain is a stop signal, not a soreness signal
- People with unresolved injuries in the loaded joints, seek clearance from a physical therapist first
- Anyone with a recent surgery, cardiovascular limitation, or pregnancy complication without physician clearance
Progression path
Once Spider Crawl feels comfortable with your current load, progress by (a) adding reps until you can complete 12+ per set, (b) increasing resistance by 2.5-5%, (c) moving to harder variations such as single-limb or longer lever versions, and eventually (d) stepping up to intermediate-level movements that train the same muscle.
See the Progression guide for a full framework on when to advance, and the Compound vs Isolation guide to decide when to prioritize this movement in your program.
Safety notes · BODY-ONLY · PULL/COMPOUND · FLOOR
- On PULL/COMPOUND abdominals work, warm up 5–10 minutes before loading Spider Crawl; keep first sets light until the path feels automatic.
- Sharp or joint pain is a stop signal. Muscle soreness during sets is normal; pain is not.
- Beginners on BODY-ONLY gear: cut volume before cutting form, drop a set rather than rush reps.
- General information only. Consult a physician or certified trainer before starting any new exercise program.

Using the spider crawl
Three ways to put it to work.
- Train the abdominals 2–3 times a week with 48+ hours between hard sets; pair this with other abdominals movements for balanced development. All abdominals exercises
- Match the load and rep range to your goal, strength, size, or endurance each call for a different scheme. Strength vs hypertrophy
- As a compound lift, this trains several muscles at once, anchor your session around it before isolation work. Compound vs isolation
Form before load. If a movement causes sharp or joint pain, stop and substitute a safer alternative, this is general information, not medical or training advice.
