Spiderman Plank

Instructions

1. Set up in a forearm plank with elbows under shoulders, body in a straight line from head to heels, and core braced.
2. Drive one knee up toward the same-side elbow, keeping your hips level and your torso stable.
3. Pause briefly as you squeeze the obliques, then return the leg to the plank position under control.
4. Repeat on the opposite side, alternating legs while keeping your back flat and hips from sagging.
