1 Thai Plank
Sets: 3 Reps: 5-10 (each side)
Get into pushup position and then bend your elbows so your forearms are fl at on the floor (A). Rotate your body to the right, raising your right arm and right leg off the floor and bringing them together so your elbow and knee touch. Brace your core hard and hold for three seconds (B). Repeat on the opposite side. If that's too difficult, perform the exercise on your knees.
