BioFitness Systems was originally incorporated by Steven Zeigman in South Carolina in 1984 with the purpose to be an innovator in Strength is Health efficacy through Managed Strength Care


BioFitness Systems maintains Professional Healthcare safety standards by using a Physical Activity Readiness Questionnaire (PAR- Q) to screen for health conditions recommending a Medical Provider prescription, to participate in a “controlled adaptation” Managed Strength CareTM exercise program.
See White Papers: Physicians & Strength for reducing risk-factors
BioFitness reduces Patient risk factors by pre-planning Strength Prescriptions designed to fit and deliver efficacious strength gain on expected timetables, enabling the high-risk unfit Patient to know, in advance, exactly how many weeks it will take for them to become muscle strength healthy, using 3 weekly sessions of 15 minute or less…followed by elective continuance or maintenance.

The difference between BioFitness PRISM A.I.™ and other resistance systems is that the BioFitness PRISM A.I.™ predicts the absolute optimized strength gain, for the client/patient, ahead of time, with a dated on-time delivery. The BioFitness PRISM AI designs the personalized strength health prescription to fit the client/patient capacity, by planning the exact number of Sets, Reps, and Weight(s) to do day-by-day, for a predetermined scheduled dependable safe success.

The High Pull is a large % of the major muscles of the body. The "triple extension" of the ankle, knee and hip joints involve the calf plantar flexor muscles (gastroc and soleus), knee extensors (quadriceps), and hip extensors (hamstrings and gluts). The torso is stabilized by the quadratus lumborum and spinal erectors. The traps control the final "shrug" with the deltoids and elbow flexors assisting.
You also have muscles active isometrically to maintain the grip on the bar. Most of the above are muscle groups, so if you count them individually you have dozens of muscles throughout the body involved in the high pull. Thus, I call it a total body exercise.
