TuffStuff Fitness BIO-ARC Series Plate Loaded Leg Extension

TuffStuff Bio-Arc Plate Loaded  Leg Extension is a great way to improve your exercise facility’s leg training circuit.  Part of TuffStuff’s most innovative commercial strength series, the Bio-Arc Leg Extension is specifically designed and tested for optimal biomechanics.  The result is a machine that maintains hip angle/pelvic tilt to optimise 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
  • Maintains hip angle / pelvic tilt to optimize muscle length
  • Greater muscle contraction during full extension
  • Free flow leg roll automatically adjusts to different leg lengths
  • Quick release allows for easy adjustments
  • Custom upholstery and frame colors available
  • Full Commercial Warranty

The Bio-Arc Leg Extension is one of the most popular machines in the Bio-Arc line-up.  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 Extension allows for a full range of motion and greater muscle contraction during full extension (outperforming traditional fixed position equipment).

Additionally, the Bio-Arc Leg Extension maintains hip angle/pelvic tilt to optimize muscle length throughout the entire leg extension motion.  Please note: the Bio-Arc Leg Extension comes equipped with a 200 lbs. weight stack; the weight lifted is the approximate combined user’s weight and weight selected.
