FAQs

How do I adjust for extensions vs. curls?
Use the ROM selector and pad adjustments to flip from extension to curl positions in seconds.

What muscles are targeted?
Leg extensions bias the quadriceps; leg curls target the hamstrings with glutes as stabilizers.

Is the stack heavy enough?
Yes—our selectorized stack is tuned for progressive overload; heavier stack upgrades are available.
