What
exercise accomplishes: Curls shape the entire
biceps area. 21,s are a combination of partial- and full-range movements,
they are a great test of stamina.
Implementation:
Seated or standing, take a
dumbbell in each hand, holding the weights at arm's length down at your
sides. Curl the weights upward but stop halfway, when your forearms are about parallel to the floor, lower them again to the starting
position. Do 7 repetitions of this movement. without pausing, curl
the weights all the way up but stop halfway down and do 7 repetitions of
this partial movement. At this point, even though exhaustion will be
tremendous, finish off the set by doing 7 full-range Dumbbell Curls. This kind
of pain definitely separates the best from the average.
