Single Arm Tricep Curl

START

CLOSE UP THUMB

FINISH

Lie face up on a flat bench, holding a suitably weighted dumbbell in your right hand, with your arm straight, the weight above your shoulder.

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.
