1 Arm DB Extensions

Lie face up on a Swiss Ball, with your thighs horizontal to the floor, having your back on the ball, holding a suitably weighted dumbbell in your right hand, with your arm straight, the weight above your shoulder.

START

focus on keeping your upper arm vertical

FINISH

avoid hitting your head as you lower the weight down

Support the position of your arm by wrapping your left hand around the outer side of your upper arm, keeping your thumb away from the inside of your elbow joint.

Focus on keeping your upper arm vertical, as you smoothly lower the weight down to the side of your head, taking care not to hit your head with the weight.

Exhale as you lift the weight back up to your starting position, prior to repeating for desired reps, then changing arms.
