Thoracic Extension over Foam Roller

A supine mid-back opener: the roller sits under the shoulder blades and the upper spine extends over it, hips down.

How to do it

  1. Sit on the floor with knees bent and a foam roller behind you, then lie back so it sits across the mid back.
  2. Cross the arms over the chest, or support the head, and keep both feet flat.
  3. Press the hips into the floor and keep them there for the whole drill.
  4. Slowly let the upper spine extend back over the roller, chest opening.
  5. Return the torso to the starting angle without sitting all the way up.
  6. Repeat, then shift the roller a little up or down the mid back if you need another segment.

Key technique cue

Hips stay down; extend over the roller through the mid-back, not the low back.

Common mistakes

  • Bridging the hips so the low back does the arch instead of the mid back.
  • Dropping the head back with no support, which dumps the work into the neck.
  • Bouncing at end range instead of moving slowly.
  • Turning the drill into a sit-up by curling the whole trunk off the roller.

Benefits

  • Gives the mid back a fulcrum so it can extend without the low back taking over.
  • Fits warm-ups before pressing or overhead work when the T-spine feels stiff.
  • The crossed-arm setup keeps the neck out of the motion.

About the exercise

Thoracic extension over a foam roller is a mid-back mobility drill, not a crunch and not a lumbar bridge. Lie supine, support the head, extend the upper back over the roller, then return. The roller sits across the shoulder blades with the knees bent, the hips staying on the floor and the arms crossed or the hands behind the head.
