SETUP: Set your bench to a 45 degree incline and lean into it (stand on your tip toes). Pull your elbows tight to your sides like a T-Rex. This is your start point.
REP: Keep your chest up and shoulders back as you try to push the dumbbells back behind your body by straightening each arm. This will light your triceps on fire, and if you’re doing a high rep set you might even feel it across your upper back.
TIP: For extra difficulty, add a momentary pause to the peak contraction of each rep and squeeze your triceps hard.
