Work your upper body while challenging the core with this circuit from @urbnburn! Do each move for 40 seconds and rest for 20. Start with 2 sets and work your way up to 4. 1. Arnold Press: While sitting on the ball, start with your palms facing your chest. As you press up, rotate your palms to face out. 2. Stirring The Pot: In prone plank, support on your elbows and circle the arms as though you are stirring the pot. *Note, this can be done on the knees as well. 3. Chest Flys: Start with your spine on the ball, feet on the floor. Keep the elbows slightly bent as you travel a half circle, bringing your arms out. Bring the arms back to center and repeat. 4: Reverse Chest Flys: Balance on the ball on your belly, feet touching the floor. Squeeze the glutes to stabilize. Keeping the elbows slightly bent, pull those arms apart. Repeat by bringing the arms together. #upperbody #upperbodyworkout #core #corecircuit #stabilityball #workout #workoutroutine #fitness #fitnesstraining #workoutathome...
