The TuffStuff Bio-Arc Leg Press (BA-709) is part of the most innovative commercial strength equipment line-up available. Whether your clients are novices or experienced with weight machines, the Bio-Arc Leg Press is straight-forward and easy to use. The user’s entire body moves along a linear arc trajectory with the machine to optimize muscle recruitment.
The Bio-Arc Leg Press allows for a full range of motion, and greater muscle contraction during full extension, outperforming traditional fixed position equipment. The large foot pad allows users to position feet in a wider stance to increase adductor recruitment when desired. Includes 400 lbs. weight stack: weight lifted is the approximate combined user’s weight and weight selected (see Weight Guide label).
TUFFSTUFF BIO-ARC RESEARCH AND DEVELOPMENT
TuffStuff is proud to introduce the Bio-Arc strength series, the first resistance machines to incorporate multi-planar movement of each machine’s seat, along a linear arc trajectory. The seat movement allows the user to move along the arc path in conjunction with the machine helping to maintain more optimal muscle length and improving the force of contraction and training stimulus. Three years in the making, from concepts and engineering to prototype, testing and refinements. Each of the Bio-Arc line’s machines were tested, following initial design positioning, by an independent exercise consulting company. Pilot research studies combining joint positioning – using goniometry testing, along with muscle recruitment and activity measurements – through electromyographic (EMG) testing were performed to determine the optimal dimensions of each unit for final production. Every detail and design modifications were executed to exact specifications and re-tested. The end result is our patented Bio-Arc Technology that allows full body linear arc trajectory motion during execution of the exercise.
