Start kneeling on the floor and place the BLACKROLL® crosswise in front of your knees. Keep your torso upright and lace your fingers behind your head.
Slowly raise the right knee off the floor and bring it forward over the BLACKROLL®. Make yure to keep your hips tight, not moving laterally or dropping during the movement. Return the right leg over the roller on the floor and start with the left side. Do 10-15 reps of this exercise.
