Short answer: Perform one strict push-up, widen the feet and tap the opposite shoulder with one hand. Replace it, then alternate. Keep hips as level as practical and move slowly.
Correct form
Brace before lifting the hand and shift only enough weight to stay stable. Tap lightly rather than holding a long one-arm plank.
Muscles worked
The press uses chest, triceps and shoulders. During the tap, obliques, glutes and the supporting shoulder resist rotation.
Regressions
Use an incline, tap from the knees or practice high-plank taps without a push-up. Compare the rotational T push-up.
Mistakes
Feet too narrow, rushing, hips twisting and collapsing into the supporting shoulder are common. Widen the base before adding speed.
Tap, reset, keep the battle moving
RepSaga makes the completed push-up the attack while you keep the tap deliberate and controlled.
Frequently asked
Do shoulder taps work abs?
They challenge the trunk to resist rotation, especially when performed slowly.
Should my feet be together?
A wider stance is more stable; narrow them only as control improves.
