Dumbbell Tricep Extension Exercise
1. Begin by sitting or standing. Place your feet shoulder width apart and flat on the floor. Keep your torso straight and head up. Grip one dumbbell and position both of your hands underneath one end of the dumbbell. Straighten your arms above your head and hold the weight vertically with your elbows pointing straight forward.
2. Slowly lower the weight down behind your head by hinging at your elbows until you arms are bent to 90 degrees. Keep your elbows pointing forward and close to your head. Be careful not to hit your head with the weight. Pause at the bottom for one second. Press the weight up using your triceps until your arms are straight overhead. Pause at the top for one second. Repeat.
3. Inhale as you lower the weight down; exhale as you press the weight up.
