How to do a dumbbell lying triceps extension

Setup:

1. Position: Lie flat on a bench with your feet firmly on the floor.
2. Grip: Hold a dumbbell in each hand and press them up so they are directly above your chest. Your palms should be facing each other (neutral grip).

The Movement:

1. Lowering: Keeping your upper arms stationary, bend at the elbows to slowly lower the dumbbells towards the sides of your head.
2. Stretch: Lower the weights until your forearms are just past parallel to the floor, feeling a stretch in your triceps.
3. Extension: Exhale and press the dumbbells back to the starting position by extending your elbows. Squeeze your triceps at the top.

Tips:

• This exercise is often called a "skull crusher," so control is crucial. Don't let the weights drop.
• Keep your elbows from flaring out too much to maximize triceps engagement.
• Only your forearms should be moving; your shoulders and upper arms should remain still.
