If you're looking to train both your inner and outer thighs comfortably and effectively—but want to keep it simple—the S2IOT stands out as a smart choice. With its intuitive design and commercial-grade stability, it supports inner and outer thigh training with a straightforward setup.
Two exercises in one seat
Transition between adduction (inner thigh) and abduction (outer thigh) by swiveling the knee pads without changing position.
Seven-position cam adjustment
Provides seven cam positions to support alignment for users of different heights.
Supportive setup
Hand grips and two-position foot supports keep you secure and stable as you work through your range of motion.
Soft, durable padding
Thick DuraFirm cushions provide padding and support during use.
Solid, commercial build
Crafted with 2"×3" heavy-gauge welded steel and a fully shrouded weight stack for durability and to enclose moving parts.
Scalable resistance
Comes standard with a 160 lb stack, with an optional 235 lb upgrade
No screens or complex controls—just intuitive mechanics. You step in, grip the handles, adjust the cam to match your height, and start moving. The motion is guided smoothly by the cam system, with clear labeling for adjustments.
