Stand facing a cable machine with an SZ-bar attached to a high pulley. Grasp the bar with an overhand grip about shoulder-width apart. Keeping your elbows tucked to your sides and upper arms stationary, push the bar downward by extending your elbows until your arms are nearly straight. Slowly return to the start position with control, maintaining tension on the triceps throughout the movement.
Log your cable triceps pushdown (sz bar) sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
