Hold a rope handle in front of you with a high cable attachment with the elbows flexed and palms facing each other. Keeping the trunk braced tightly, and the elbows close to the sides, extend the elbows maximally, then return to the top under control. The rope can be spread to the sides and the hands pronated partially as you extend, or you can maintain the same neutral grip throughout.
 
Purpose
The rope tricep pushdown is an effective way to isolate the triceps for strengthening elbow extension and general elbow stability. The rope handle increases grip work and the neutral grip shifts somewhat more emphasis to the lateral head of the tricep than a pronated grip.
 
Programming
Generally sets of 6-15 reps are appropriate.
