This Life Fitness Pro 1 workout machine works on the biceps brachial muscle. The user is in a seated position, usually with the back of the forearm resting on a cushion, grasping the grips, lifting the load weight by bending the elbow and pulling the handles towards the body.
Features
Arm pad
Configured to align elbows off pad in order to reduce joint compression and extend pad life
Frame
Constructed primarily of U.S. manufactured 2" (5 cm) sq 11-gauge wall thickness steel tubing
Each part is sandblasted prior to finish to prepare the surface for maximum adhesion
Epoxy powder coat finish
Weight Stack
Solid steel weight plates
Top weight plate is fitted with self-lubricating and self-cleaning bushings
Low-friction bushings contained in each plate eliminate metal-to-metal contact between plates and guide rods
7/16" (1 cm) diameter weight selector pin magnetically locks in place and is connected to stack to prevent loss
Shock-absorbing durable rubber bumpers under each stack reduce vibration
Weight stack is guarded on back to prevent inadvertent contact during use
Seat And Lever - Arm Adjustment
Most units use a Quick ClickTM ratcheting seat adjust system which adjusts in 1/2" (1 cm) increments
Some back pad adjustments are spring-loaded, adjusting from the exercise position
No metal-to-metal contact reduces friction for easier adjustment and increased life
Lever-arm adjusters use a patent pending four-bar linkage mechanism and adjust in three positions
