TRICEPS
Single Arm Dumbbell Tricep Extension
A one-armed overhead extension that zeroes in on a single triceps at a time. Working each side on its own forces the weaker arm to pull its own weight and adds a stability demand you don't get with two hands.
How to do it
- 1
Sit tall on a bench with your core tight.
- 2
Hold a dumbbell in one hand and press it straight up over that shoulder, palm facing forward.
- 3
Keep your upper arm pointing at the ceiling as you bend the elbow to drop the weight behind your head.
- 4
Lower until your forearm nearly touches your bicep, keeping the dumbbell close to your head.
- 5
Press back up to the top, then finish your reps and switch arms.
