TuffStuff Fitness BIO-ARC Series Plate Loaded Leg Curl

The Bio-Arc Plate Loaded Leg Curl 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
  • Quick release allows for easy adjustments
  • Custom upholstery and frame colors available
  • Full Commercial Warranty

The Bio-Arc Leg Curl is part of TuffStuff’s most innovative commercial strength series.  With each repetition, the user’s entire body moves along a linear arc trajectory to optimize muscle recruitment.  As a result, the Bio-Arc Leg Curl allows for a full range of motion and greater muscle contraction at full curl (outperforming traditional fixed position equipment).

Additionally, the Bio-Arc Leg Curl maintains hip angle/pelvic tilt to optimize full contraction of the hamstring muscles, while limiting joint stress.  Please note:includes 200 lbs. weight stack, the weight lifted is the approximate combined user’s weight and weight selected.
