Segmental Press Up

Open floor or yoga mat

Lie face down on the floor and place your hands just outside of your shoulders
Start the movement by tilting your head back and looking up. Imagine that you are moving one segment of your spine at a time
Continue extending your spine one vertebrae at a time
As your chest lifts off the ground begin pushing with your hands to help support your weight
Go slowly and focus on each segment as it moves into extension
Continue until your elbows are fully extended
Complete the prescribed repetitions

Many people go too fast, missing the chance to mobilize every segment along the way. Go slow and focus.

If this is too challenging:

Perform partial reps until you feel like you can move through your restriction
If you have a friend that can help have them place the side of their hand on top of individual vertebrae to give you feedback and a block to try and bend around.
