Categories: ,

TuffStuff’s Bio-Arc Mid Row (BA-706) is an excellent way to improve your exercise facility’s strength training circuit.  Part of the most innovative commercial strength series available, the Bio-Arc Mid Row is specifically designed and tested to promote optimal biomechanics.  The result is a machine with independent movement of the hands and arms to minimize stress, and a seat that moves along a linear arc to increase Latissimus activation throughout the entire range of motion.

  • Optimal Mechanics for Muscle Activation
  • User’s body moves along a linear arc trajectory to optimize muscle recruitment
  • Trak Swivel handles enable a full range of motion and rotational movements
  • Intuitive with minimal adjustments required
  • Stabilizes and positions user to target lower/mid trapezius and rhomboid muscles
  • Independent handles allow natural arc pattern and movement of joints, limiting stress
  • Custom upholstery and frame colors available

Designed and independently tested with optimal biomechanics in mind, the Bio-Arc Mid Row (BA-706) is part of TuffStuff’s most innovative commercial strength series.  Each machine comes equipped with TrakFitness 360° swivel handles.  The first and only handles to include 3 axis of rotation, allowing the user to move through multiple planes of motion.

The Bio-Arc Mid Row targets and strengthen the (latissimus dorsi) back muscles.  Additionally, it engages other muscles important to back strength and function, including the posterior deltoids at the back of the shoulders and the rhomoboids and trapezius of the upper back.  Strengthening these muscles creates a desirable v-shape that makes your upper body look strong and wide, while giving the appearance of a smaller waist.



TuffStuff Bio-Arc Technology - Independent Machine TestingTuffStuff 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 >
