Diagonal Plank

Muscles worked: Abs & Core, Legs · Also: Legs & Glutes, Glutes & Hips, Back

Diagonal Plank is a plank variation that adds a diagonal reach: from a plank, you extend one arm and the opposite leg, hold briefly, then switch sides.

The plank itself comes first — hips level, core braced — and the reach is secondary. Only extend as far as you can without your hips twisting or dropping, and return to a solid plank between reaches.

How to do it

1. Set a plank with your hips level and your core braced — the plank itself comes first.
2. Extend one arm and the opposite leg, holding briefly.
3. Return to a solid plank, then switch sides.
4. Only extend as far as you can without your hips twisting or dropping.
5. The reach is secondary — return to a solid plank between reaches.
