These are a valuable exercise for targeting and strengthening the triceps, the muscles at the back of your upper arms. It is typically performed using a cable machine found in most gyms. It's an effective exercise to strengthen and tone the triceps while offering the benefit of constant tension on the muscle throughout the entire range of motion.
First, place the cable pulley as low as possible, then grab the handle in one hand and position yourself facing away from the pulley. Move slightly forwards, then have your elbow pointing up and your hand pointing down.
This is the starting position.
From here extend your hand up and above your head, by extending at the elbow until the arm is fully extended or as far as you can. After this, slowly return the arm down to the starting position. This is one repetition, now repeat this for the desired amount. Once you’ve done all the reps on one arm, if required in the program and you are able to do so, repeat the exercise and the repetitions with the other arm.
If you have limited gripping ability try using the Active Hands Gripping aids or D-Ring Aids clipped straight into the carabiner to make this exercise as safe as possible.
