The triceps are much more crucial than the biceps for bigger arms since two-thirds of your upper arm is composed of triceps, which consist of three sections: 1) Long, located on the back of the arm; 2) Lateral, which gives you the “horseshoe” effect; and 3) Medial, located on the lower part of the arm. This tricep workout will incorporate exercises that hit all three.
Warm up:
Arm circles: 30 seconds to warm-up the shoulders
Light cable pushdowns: two sets of 20, using very little weight to focus on squeezing your elbows together at the bottom of the pushdown to hydrate your elbow tendon
Overhead reach: 30 seconds, to stretch your lats and triceps.
