One-Arm Push-Up
Feet wide, one hand behind the back: lower on a single arm while the trunk resists twisting.

How to do it
Setup
Feet WIDE, working hand under the chest's center, other hand behind the back.
Steps
- Lower on the single arm, trunk fighting the twist.
- Chest toward the floor, hips level.
- Press back up without rolling.
Common mistakes
Hips rotating open: the anti-twist IS half the exercise; wider feet help. Tiny range sold as reps: depth grows with strength; be honest. Elbow flaring: it tracks back.
Breathing
Inhale down, exhale pressing.
