The only difference in this movement versus a 2-hand lat stretch with the stability ball is you do one arm at a time. In this variation, it is more important to maintain stability and roll the ball in a straight path.
Place the stability ball firmly on the floor and kneel down in front of it, both your knees should be side by side and one hand on top of the ball, the other hand straight down on the ground in front of you.
How to Do:
1. To begin the stretch, slowly roll the ball away from you with one hand hand firmly placed on top of it, until you feel pressure in your Latissimus Dorsi..
2. Once a stretch is felt, hold that position for 20-30 seconds and repeat 2-3 times before switching arms.
