Tri 1: Arm and Leg Reach

Work your core, emphasizing the deepest abdominal muscle, the transverse.

Get down on your hands and knees, wrists directly under shoulders. Keep your belly pulled in, your head up and shoulders down. Inhale, then exhale as you lift your right arm and left leg to shoulder height. Release and repeat with left arm and right leg. Do 5 reps on each side.
