Elbow extension

Also called: Tricep kickback, Dumbbell kickback, Dumbbell triceps kickback, Bent-over triceps extension, Cable triceps kickback, Cable tricep kickback

The short answer

The triceps kickback is a bent-over isolation exercise: with your torso hinged forward and your upper arm pinned at your side, you straighten your elbow to move a dumbbell back until your arm is straight. It trains the triceps on their own and is usually done light, for higher reps, near the end of an arm or upper body session.

How to do it, in one breath

Hinge forward with a flat back, upper arms tucked at your sides and elbows bent. Straighten your arms behind you, squeeze, and return. Only your forearms move.

How to set up

  1. 01

    Pick a light dumbbell. Start lighter than you think. Most people kick back far less than they curl, and form breaks fast when the weight is too heavy.

  2. 02

    Support yourself. For one arm, put the knee and hand of your non-working side on a flat bench, or stand in a staggered stance with your free hand on the bench. For both arms at once, stand with feet hip width and knees soft.

  3. 03

    Hinge forward. Push your hips back and bring your torso close to parallel with the floor, back flat and neck in line with your spine.

  4. 04

    Pin the upper arm. Lift your working upper arm until it is level with your torso and tucked against your side. It stays there for the whole set.

  5. 05

    Start bent. Let your elbow bend to about 90 degrees so the dumbbell hangs straight below your elbow, palm facing in.

Step by step

How to do the triceps kickback

  1. 01

    Brace. Take a breath and tighten your midsection so your torso does not twist or rise as you lift.

  2. 02

    Extend. Straighten your elbow and move the dumbbell back and up in an arc until your arm is straight and in line with your torso.

  3. 03

    Squeeze. Hold the straight arm for about one second and feel the back of your upper arm working hard.

  4. 04

    Lower. Bend your elbow and bring the dumbbell back down under control until your forearm hangs straight down, at the 90 degree start. Do not let it swing forward past your elbow.

  5. 05

    Repeat. Keep the upper arm still on every rep. If you are working one arm at a time, finish all reps on that side before you switch.

Cues to say in your head

  • Elbow pinned to ribs
  • Only the forearm moves
  • Lock out and squeeze
  • Slow on the way down
  • Flat back, long neck

Fix these first

Common mistakes

  • Swinging the weight up

    Use a lighter dumbbell and pause at the top. If you need momentum, the triceps are not doing the work.

  • Upper arm dropping toward the floor

    Keep the upper arm level with your torso. When it hangs down, the range shrinks and the weight tends to swing instead of the triceps doing the work.

  • Elbow drifting as you extend

    Keep the elbow in one spot at your side and let only the forearm move.

  • Stopping short of a straight arm

    Finish each rep with the elbow straight. If you cannot, the weight is too heavy.

  • Rounded back

    Hinge from the hips with your back flat, and on the one arm version lean on the bench so your back stays supported.

  • Bent wrist

    Keep the wrist straight and in line with the forearm. Do not flick the dumbbell up at the end.

Stay safe

Kickbacks use light weights, so the main risks come from a rounded back or forcing the elbow. Use a bench for support if your lower back tires, and lower the dumbbell under control to the start on every rep. If you cannot reach a straight arm with control, simply end the set and set the dumbbell down. Stop if you feel sharp pain in the elbow or shoulder, and get it checked if it keeps coming back.

Put in a recent set. You get working weights for your goal, a warm-up and the plates to load.

Estimated 1RM 216 lb

Endurance sets

108–134lb

2 to 3 sets of 15 to 20 reps, 45 to 90 sec rest. Light sets that work well as a finisher at the end of an arm or upper body day.

Estimates use the Epley formula and work best from sets of 3 to 8 reps. Treat them as a starting point and adjust by how the first working set moves.

Questions

Triceps Kickback questions

What muscles do tricep kickbacks work?

Kickbacks work the triceps, the muscle on the back of your upper arm that straightens your elbow. Your rear delts and upper back hold your arm in place, and your lower back holds the hinge.

How do you do a cable tricep kickback?

Set a single handle on a low pulley, or hold the cable just above the stopper with no handle, and hinge forward facing the machine. Pin your upper arm at your side and straighten your elbow back until your arm is straight, then return under control to 90 degrees.

Are tricep kickbacks worth doing?

Yes, as a light accessory for extra triceps work, especially when you only have dumbbells. They work best done strictly for higher reps after your main pressing or triceps exercise.

How heavy should tricep kickbacks be?

Light enough that your upper arm stays still and you can reach a straight arm with a pause on every rep. That is usually much lighter than your curl weight.

How many sets and reps of tricep kickbacks should I do?

For muscle growth, 2 to 4 sets of 10 to 15 reps, taken close to failure, is a good default. Add reps first, then move up to the next dumbbell.

Should I do kickbacks one arm at a time?

One arm at a time with your free hand on a bench is the easiest way to keep your back flat and your upper arm still. Doing both arms together saves time but takes more effort to hold the hinge.
