Is this machine plate loaded or selectorized?

This machine is plate loaded. You can use your own Olympic plates for smooth resistance and progressive overload.

Will this leg extension & curl machine fit in a home gym?

Yes. With a compact 45” × 45” × 45” footprint and transport wheels, it’s built to fit residential spaces like garages, basements, or dedicated training rooms.

What muscles does this machine train?

Leg extensions isolate the quadriceps, while seated leg curls target the hamstrings. Together they provide a complete lower-body workout.

How do you use the dual function design?

For leg extensions, place ankles under the rollers and extend to train the quads. For seated leg curls, adjust the pads and curl the roller back to hit hamstrings. Switching exercises takes just seconds.

What is the maximum load capacity?

The 10” Olympic sleeve holds up to four 45 lb plates for a total of about 180 lbs of resistance.
