What you'll gain

• Isolates the triceps with strict single-joint loading.

• Builds the back of the arm without pressing assistance.

• Improves elbow lockout strength for compound presses.

Step-by-Step Instructions

1. 1

   Stand with a dumbbell in one hand and a slight bend in your knees.

2. 2

   Hinge forward at the hips until your torso is at about 45 degrees and your back is flat.

3. 3

   Pin your working upper arm against your side with the elbow bent at 90 degrees.

4. 4

   Extend the elbow to swing the dumbbell straight back behind you until the arm is fully locked out.

5. 5

   Squeeze the triceps hard at the top with the dumbbell behind you and the upper arm still pinned.

6. 6

   Lower the dumbbell back down to the bent-elbow start, then repeat for reps before switching arms.

Common Mistakes

• Letting the upper arm drop or swing during the lift, which turns the kickback into a row.

• Going too heavy and using momentum, which makes the triceps work disappear from the lift.

• Cutting the lockout short and not fully extending the elbow, where the triceps fully shorten.

• Rounding the lower back instead of hinging with a flat back, which puts the spine at risk.

About This Exercise

The dumbbell tricep kickback is one of the cleanest isolation lifts for the back of the arm. Hinging forward with the upper arm pinned against the side of the body and extending the dumbbell straight back forces the triceps to do all the work without any pressing assistance from the chest or shoulders. For fitness app and coaching platform builders, the kickback is a near-essential inclusion in any arm-day block or hypertrophy track. It works especially well as an arm-day finisher with light weights and high reps, where the goal is metabolic stress and a strong squeeze rather than maximum load. Pair it in your library with skullcrushers and overhead extensions for a complete triceps assortment.
