Lower the bar down to the knees, as if you were doing a Romanian deadlift.
Explode into a vertical jump while holding the bar. Do not pull the bar. The arms stay straight.
Don't lower the bar too slowly. Just keep it under control. Be sure to finish the hip extension; make yourself "tall." Don't be surprised if you jump backward a bit when you get it right.
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.
