For correct tricep pulldown form, stand with your feet shoulder width apart with your knees slightly bent. Grab the bar with an underhand grip, lock your elbows by your side and then pull down on the bar until your arms reach lockout position. Slowly resist the cable upwards, then repeat.

To maintain proper form during tricep pull downs, start by standing upright with elbows tucked in and feet hip-width apart. Grab the bar and pull it down until it touches your thighs. Squeeze your triceps at the bottom of the move.
