The TuffStuff Bio-Arc Triceps Dip (BA-704) primarily engages the triceps, but also works the anterior deltoid, the pectoralis muscles, and the rhomboid muscles of the back.  Each Bio-Arc machine safely places users of all sizes and physical abilities in the optimal position to perform each exercise with minimal adjustments necessary.  The Bio-Arc Triceps Dip is designed with head, back and seat pads positioned to maintain neutral positions.  And it comes equipped with TrakFitness cable handles.  The first and only handles to include 3 axis of rotation, which allows users to move through multiple planes of motion.  With each repetition, the user’s entire body moves along a linear arc trajectory to optimize muscle recruitment.

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 prototypes, to testing and countless refinements.  Each Bio-Arc machine was tested 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.  Each machine was tested to determine the optimal dimensions for final production.  Every detail was measured, 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 exercise. Learn more >
