Upper Body and Core Metabolism-Boosting Exercises
Starting position: Stand up in split-stance position, with your right leg forward, holding a dumbbell in your left hand. Place your right hand on your right thigh and slowly lean forward to 45 degrees while keeping your head in line with your spine. Keeping your left arm close to your body, bend your left elbow so that your forearm is vertical to the floor. Keep your abs engaged.
Kickback: Extend and straighten your elbow while keeping your upper arm close to your torso. Slowly bend to bring back to starting and repeat.
Modification: For more advanced kickbacks, keep your feet together, use a weight in each hand, and lean over so that your torso is parallel to the floor. Or for more support, use a weight bench and place your opposite knee on the bench.
