Bio-Arc Strength Equipment

The revolutionary Bio-Arc strength series includes the first resistance machines to incorporate multiplanar 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.

BIO-ARC SEATED CHEST PRESS

TuffStuff’s Bio-Arc Seated Chest Press (BA-701) 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 Chest Press provides a seamless spotter-free chest press experience.  Simply sit in the seat, grab the handles and press.  No seat adjustments required.  As the user extends the independent swivel handles, their entire body moves along a linear arc trajectory with the machine to optimize muscle recruitment.

BIO-ARC LAT PULLDOWN

The TuffStuff Bio-Arc Lat Pulldown (BA-705) is a phenomenal way to improve your exercise facility’s strength training circuit.  Designed and independently tested to ensure proper biomechanics, the Bio-Arc Lat Pulldown keeps the user’s entire body moving along a linear arc trajectory to optimize muscle recruitment.  With TrakFitness 360° swivel handles, users may perform unilateral or bi-lateral movements.  And the independent movement of the hands and arms minimizes stress, while also increasing Latissimus activation through the entire range of motion.

BIO-ARC SHOULDER PRESS

TuffStuff’s Bio-Arc Shoulder Press (BA-702) is part of the most innovative commercial strength equipment line-up available.  Bio-Arc Shoulder Press provides a seamless workout experience, simply sit in the seat, grab the handles and press.  No seat adjustments required.  As the user extends the independent swivel handles, their entire body moves along a linear arc trajectory with the machine to optimize muscle recruitment.

BIO-ARC BICEPS CURL

TuffStuff’s Bio-Arc Biceps Curl (BA-703) is an excellent choice to improve your exercise facility’s strength training circuit. Whether your clients are novices or experienced with weight machines, the Bio-Arc Biceps Curl provides a seamless experience.  Simply sit in the seat, grab the handles and curl.  No frustrating adjustments required.  As the user pulls the independent swivel handles, their entire body moves along a linear arc trajectory with the machine to optimize muscle recruitment.

BIO-ARC TRICEPS DIP

The TuffStuff Bio-Arc Triceps Dip (BA-704) 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 Triceps Dip provides a seamless experience.  Simply sit in the seat, grab the handles and press down.  No seat adjustments required.  As the user extends the independent swivel handles, their entire body moves along a linear arc trajectory with the machine to optimize muscle recruitment.

BIO-ARC MID ROW

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.

BIO-ARC LEG PRESS

TuffStuff’s Bio-Arc Leg Press (BA-709) is a phenomenal way to improve your exercise facility’s leg training circuit.  Part of TuffStuff’s most innovative commercial strength series, the Bio-Arc Leg Press is specifically designed and tested for optimal biomechanics.  The result is a machine with head, back, and seat pads that promote neutral positions.  And a dynamic seat that moves along a linear arc with the user to increase Quadricep and assisting muscle activation throughout the entire range of motion.

BIO-ARC LEG CURL

The Bio-Arc Leg Curl (BA-708) 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.

BIO-ARC LEG EXTENSION

TuffStuff Bio-Arc Leg Extension (BA-707) 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 optimize muscle length throughout the entire range of motion.
