* Set up the cable pulley so it’s just above head height and attach a straight bar or rope attachment – this should hang around chest height.
* Adopt a hip-width stance and grip the attachment.
* Slightly bend the knees, engage the core, and pin your shoulder blades back.
* Keeping your elbows and upper arms close to your sides throughout, squeeze your triceps as you push the load downwards until your arms are extended.
* To complete the rep slowly, allow the weight to return to the starting position.
