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.
