The Bio-Arc Leg Curl (BA-708) is part of TuffStuff’s most innovative commercial strength series. Over a period of three years, TuffStuff tested and modified nearly every component on the machine. Each design was independently tested – using goniometry testing, along with muscle recruitment and activity measurements through electromyographic (EMG) – and then adjusted and refined for optimal biomechanics. The end result is the Bio-Arc Leg Curl, which maintains hip angle/pelvic tilt to optimize muscle length throughout the entire range of motion.
Optimal Mechanics for Muscle Activation
User’s body moves along a linear arc trajectory to optimize muscle recruitment
Greater range of motion and muscle contraction at full curl
Maintains hip angle / pelvic tilt to optimize muscle length
Free flow leg roll automatically adjusts to different leg lengths
Leg, back and seat pads designed to maintain neutral positions
