1) Start seated with knees bent and feet flat on the floor. Keeping core engaged, lean torso back to a 45-degree angle from floor and extend right leg 2 inches off floor.
2) Explosively pull torso back to upright position while pulling right knee toward chest and shooting left arm forward. The motion looks somewhat like you’re sprinting. Repeat for desired number of reps and switch arm and leg.
Targets: core, back
