Why I do it: This has to be the ultimate bodyweight exercise for arms. I try to focus on doing quality reps with my knees off the ground to really strengthen my arms. Bending the elbows back behind me is a great way to target the triceps.
- Start in a plank position with your arms and legs straight, shoulders above the wrists.
- Keeping your upper arms parallel, bend your elbows lowering your chest until your shoulders are in line with your elbows. The elbows should touch your ribcage.
- Inhale to straighten the arms. This counts as one rep.
