2A Ball Bridge
Sets: 2-3 Reps: 5 (each side) Tempo: 232 Rest: 60 Seconds
Lie back on a Swiss ball with your arms straight out to your sides and knees bent 90 degrees . Keeping your hips elevated (in line with your body), step to one side and roll your torso in that direction until that side's shoulder is in line with your knee . Hold for three seconds, and then return to the starting position. Now lower your hips to just an inch above the floor , and then extend them to return to the starting position again. Repeat on the opposite side. That's one rep.
