This is a great chest exercise for hypertrophy if you have good motor control. Start with the incline bench set at about 45 degrees, higher than you would normally use for incline bench presses or flyes.
With a slight bend in the elbows, initiate the movement by contracting your pecs. Really try to "open up" the chest.
Don't bring the dumbbells straight down; that will just hit your shoulders. Notice the natural arcing motion of the arms. The dumbbells start at the sides and should stop above the upper chest.
It's been three weeks since I issued The BIGGER-ARMS Challenge to T-Nation members. More than 100 of you signed up to do 4 workouts – which consisted of unique biceps and triceps cycles – from May 8th to May 21st.
