Exercise Description

The one arm lying dumbbell tricep extension builds serious tricep strength and size by isolating each arm separately. This fixes muscle imbalances and gives you better control.

How To

1. Lie flat on a bench holding one dumbbell in your right hand, arm extended straight up over your chest. 2. Keep your upper arm still and slowly lower the dumbbell by bending only at your elbow until it's near your ear. 3. Feel the stretch in your tricep, then push the weight back up by extending your elbow to the starting position. 4. Complete all reps with your right arm before switching to your left arm for the one arm lying dumbbell tricep extension. 5. Keep your core tight and your back flat against the bench throughout the entire movement.

Form Tips

• Keep your upper arm locked in place - only your forearm should move during the one arm lying dumbbell tricep extension • Lower the weight slowly and control it back up - no bouncing at the bottom • Keep your wrist straight and grip the dumbbell firmly • Don't let your elbow flare out to the side - keep it pointing toward the ceiling

Common Mistakes

• Moving your upper arm instead of keeping it still ruins the one arm lying dumbbell tricep extension effectiveness • Using too much weight leads to poor form and potential injury • Rushing through reps instead of controlling the movement reduces muscle activation during the one arm lying dumbbell tricep extension
