Greater range of motion

Proper positioning
Use the squat-calf raise platform and get the support you need to properly position knees and legs when doing calf and squat-raise exercises.

Steel shrouds 
These enclosures shroud the nucleus of the cable network and extend around the weight stack to conceal moving parts.
Impressive weight stack

Optional heavier weight stack
Larger 258-pound weight stacks allow users of all fitness levels to enjoy the same results.
Greater range of motion 
Increase your range of motion, vital for achieving strength-training results, with nine different starting positions for chest and shoulder exercises.
More variety
Target any upper-body area and vary your workout with the S3.21 selector cam that lets you use the same apparatus for exercises that involve pushing and pulling.
