## Physiology
- Lumbar Anti-Extension (Rectus Abdominus, Transverse Abdominis, Obliques)
## Technique
- Push up position, elbows beneath shoulders
- Full body in straight line
- Cue: pull elbows back toward your body
- 3 sets of 20-40 second holds
## Overload
- Overload: extend the lever arm (move elbows forward), posterior pelvic tilt (squeeze glutes)
- Further overload: bring the elbows in closer together, cue to pull elbows to toes and toes to elbows
- Ab Wheel Rollout to complement
## Errors
- Hips rising up or too low
