How to do the Sit-Up
- 1
Lie down on the floor placing your feet either under something that will not move or by having a partner hold them. Your legs should be bent at the knees.
- 2
Place your hands behind your head and lock them together by clasping your fingers. This is the starting position.
- 3
Elevate your upper body so that it creates an imaginary V-shape with your thighs. Breathe out when performing this part of the exercise.
- 4
Once you feel the contraction for a second, lower your upper body back down to the starting position while inhaling.
- 5
Repeat for the recommended amount of repetitions.
Log it, see it on your body.
Every Sit-Up set you log feeds Ascend's anatomy heatmap — so your abs volume is visible at a glance — and counts toward your bodyweight-strength tier.
