Rotating from a plank into a side support, top arm reaching toward the ceiling, strings the two hardest static holds together with a controlled transition between them. The turn itself, when all your weight passes over one arm, is where most reps fall apart, so earn it slowly rather than swinging the arm for momentum.
How to do the Plank Rotation
- Start in a high plank position with your hands directly under your shoulders and your body in a straight line from head to toe.
- Engage your core and glutes to maintain a stable position.
- Rotate your torso to the right, lifting your right arm and extending it towards the ceiling.
- Keep your hips and legs stable as you twist.
- Hold for a moment, then return to the starting position.
- Repeat the twist on the left side.
- Continue alternating sides for the desired number of repetitions.
Tip: Pull the elbows toward the toes and the toes toward the elbows without moving either to fire the whole core.
Muscles worked
Primary
Abs · Core
The abs resist the hips from sagging and should feel like they are tightening more with every exhale.
Secondary
- Obliques — On side planks and rotations the obliques on the bottom side hold the hips up and should burn along the side of the waist.
- Delts — The shoulders hold the upper body up and get more work on shoulder tap variations.
Common mistakes
- Hips sagging — squeeze the glutes and tuck the pelvis slightly so the lower back stays flat; a plank with an arched back trains nothing useful.
- Hips too high — the body should be a straight line from head to heels, so check in a mirror or have someone lay a bar along your back.
- Time over tension — a two minute plank with a loose core is worse than 30 seconds with everything braced; shorten the hold and squeeze harder.
- Holding the breath — breathe normally through the hold and keep the abs braced through each exhale.
Where it fits in a workout
Planks go at the end of a session or in the warm-up to switch the core on before squats and deadlifts. Superset a front plank with a side plank each way.
