Seated Dumbbell Triceps Extensions 

Starting Position 
Sit holding one dumbbell with both hands behind your neck by grasping the plate and wrapping your thumbs and pointer fingers around the hand grip. 

Action 
EXHALE: Extend arms straight above your head, keeping elbows next to ears.  

INHALE: Lower the weight back down with control to the starting position to complete one rep. 

Special Instructions 
Contract abs to avoid arching your back. Use a bench with a short back (if available) for support. Keep elbows tight near ears throughout movement and try to keep your upper arms still.
