Plank Reach-Through

What it is

From a high plank, you reach one hand under your body toward the opposite side, rotating through the torso, then return and switch. It trains anti-rotation and rotation control on top of the usual plank work. Move slowly and keep the hips from swaying.

Technique tips

• Set a wide stance for balance
• Reach under and across with one hand
• Rotate the upper back, not just the arm
• Return to a square plank before switching

How to track your progress

Log reps, and add the extra load if you wear a belt or a vest. Straddly counts your bodyweight in the estimated max, so added weight and extra reps both show up as progress, and new records are flagged during the session.
