Exercise Advice: Grab a dumbbell with your
right hand and position your left knee and hand onto a flat bench.
Keep your arm tucked into your side at a 90 degree angle. Slowly
extend your arm out and keep your elbow in. At full extension of
the movement, make sure to keep a little bend in your arm and all
the tension on your tricep muscle. Slowly lower the dumbbell back
to the starting position. Repeat with your opposite arm.
