Steps
- 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.
Tracking it in OneRep
Add the spider crawl to a routine and your previous weight and reps sit beside every set, so the decision to add load is made by what is already on the screen rather than by memory. Exercise history and volume trends are one tap away, and logging works offline for the gyms where signal does not reach.
Because OneRep tracks food on the same timeline, a stall on this lift can be read against what you were actually eating that month — which is the difference between a programming problem and an eating one. More on that in tracking progressive overload without a spreadsheet.
Where the instructions come from
The steps above come from free-exercise-db, a public-domain exercise dataset. They are general guidance, not coaching for your body: if a movement hurts, stop and get someone qualified to look at it.
