Thoracic extension, upper back strength, posture correction

Minimum Effective Dose
1 min
The shortest time that still creates real, measurable change. Hit the dose and the benefit starts. Everything after is bonus.

Why it works

Prone thoracic extension targets the upper back extensors, which are weakened by desk posture. Strengthening these muscles counteracts the forward-rounded position and restores the ability to extend through the upper back.

How to do it

Hands behind head. Lift the chest.
Face down, fingers laced behind head. Lift your upper back only. Lower back stays quiet. Hold 3 seconds, lower. Feeling it in the neck means the chin needs to tuck slightly.
