How to do it

1. Start in a forearm plank with your elbows under your shoulders and your body in a straight line.
2. Press down through your palms and extend your elbows, lifting your whole body up into a straight-arm plank, then lower yourself back onto your forearms with control - no dropping, no walking the hands.
3. The lever is long and your triceps are the only engine, which is exactly why so few exercises hit them this directly.
