This is Gonna Hurt. Thoracic mobility for Cheap

This is just two tennis balls taped together with athletic tape. Quite sloppily I might add. This simple DIY mobility tool is a great way improve mobility of your thoracic spine which can improve your torso and back angle in the bottom positions of squats and deadlifts as well normal standing and sitting over time. To use it simply place the "peanut" under your erector muscles on each side of your spine. The ball should be somewhere above your navel. Bend the knees as if to do a sit up and lie back over the ball. (Let the discomfort begin). From this position crunch up 3-5 times keeping your back pressed against the ball and returning all the way to the floor each rep. After each set simply move your butt down so the "peanut" moves up your back and repeat the crunches. It is very helpful to give yourself a hug during these crunches to create space for the peanut. Do this until you can no longer roll the ball up your back without moving onto your neck. This little exercise will have you cursing, but it does wonders for improving thoracic mobility. Enjoy!
