2 Thai Crucifix
Sets: 3 Reps: 5-10 (each side)
Get into pushup position and then rotate to your right side, raising your right hand straight overhead (A). From there, raise your right knee and move your arm so that your knee and elbow touch while you're bracing (B). Hold for three seconds and then repeat on the opposite side. If that's too diffi cult, perform the exercise on your knees.
