Plank
Muscles worked: Abs.
How to do it
- Get into a prone position on the floor, supporting your weight on your toes and your forearms.
- Keep your body straight at all times, and hold this position as long as possible.
Coaching cues
The two cues IronPack shows on this exercise's card mid-workout:
- Glutes squeezed, ribs tucked
- Count honest seconds - quality over duration
Logging it
Logged as seconds held, with a built-in timer. Longer honest holds beat sloppy long ones.
