How to do the Plank
- 1
Get into a prone position on the floor, supporting your weight on your toes and your forearms. Your arms are bent and directly below the shoulder.
- 2
Keep your body straight at all times, and hold this position as long as possible. To increase difficulty, an arm or leg can be raised.
Log it, see it on your body.
Every Plank set you log feeds Ascend's anatomy heatmap — so your abs volume is visible at a glance — and counts toward your bodyweight-strength tier.
