Overhead Dumbbell Tricep Extension
A tricep isolation move performed with a single dumbbell held overhead in both hands to build the back of the upper arm.
Equipment: Dumbbells
How to do it
- 1Stand or sit tall, holding one dumbbell with both hands cupped under the top end, and press it overhead until your arms are fully extended.
- 2Keeping your upper arms close to your head and stationary, bend your elbows to lower the dumbbell behind your head.
- 3Once you feel a stretch in your triceps, extend your elbows to bring the dumbbell back overhead.
Common mistakes
- Letting the elbows flare outward, which shifts stress onto the shoulders and reduces tricep isolation.
- Arching the lower back to help move the weight instead of keeping the core braced.
