Alternating Lateral Lunge with Press Out-  We love the comfort and convenience of these duel handle medicine balls, but a single dumbbell or plate works great too.  Begin with feet together and weight held by both hands at your chest.  Step out wide to the left, keeping both feet facing straight ahead and sitting back into a lateral lunge.  Simultaneously brace your core and press the weight away from your body by extending your arms.  Exhale with the exertion.  Return to your starting position.  Now repeat the lateral lunge and press on the right.  Continue like this for a total of 20.

Tall Plank with Pull Through- Set up in a tall plank position with your shoulders directly over your hands and your legs about hip with apart.  Place the weight just to the left of you at chest level.  Maintaining the integrity of your plank, shift your weigh into your left hand and reach for the weight with your right hand.  Keep your core braced and your hips square as your pull the weight under and across you.  Leave it to rest at your right side.  Place your right hand back down to the ground, making corrections to your plank as needed.  Reach under with your left hand to return the weight to your starting position on the other side.  Continue for a total of 20 reps.
