RB Single Arm Triceps Extension

Grab one end of the resistance band with one hand low behind your back.
With the other hand, grab the opposite end behind your head so that your elbow is flexed.

Contract the muscles on the back of your upper arm and extend your elbow until fully extended.

Squeeze and hold the contraction for a second, then get back into the starting position.

Repeat for the recommended number of repetitions, then switch arms.
