Standing Bar Curl
It is important to use the supplied length of chain on this exercise.
Otherwise, the weight stack can easily "top out" and damage a
pulley. Attach the chain to the low pulley station (on some mod-
els, this may be at the front of the leg extension lever), and then
attach the Straight Bar to the end of the chain. Stand in front of the
low pulley with the straight bar at arms' length. Try to keep your
elbows and upper arm stationary while you curl the bar upward, us-
ing your biceps muscles. Lower slowly. NOTE: You can use either
the stationary low pulley, or the Functional Training Arm pulley.
The weight ratio for the stationary low pulley is 1:1 (10 pound
increments to 200 pounds). The weight ratio for the Functional
Training Arms pulley is .5:1 (5 pound increments to 100 pounds).
Variations: Use an overhand grip.
Primary muscles worked: Biceps (front of arm), Brachioradials
(forearms).
