The words biomechanical science, physics, thermodynamics and engineering principles may never be heard during the typical water cooler conversation after a hearty physical workout at the gym. But that doesn’t mean they shouldn’t be part of a discussion between fitness trainers and clients in matters concerning the design of fitness routines and movement makeovers intended to keep knees, hips and joints vibrant and healthy.

Experience as a fitness trainer, a Bachelor of Science degree in Exercise and a master’s degree in exercise with a focus on exercise physiology form the foundation of Jay Weitzner’s business, Symmetry Precision Fitness, where he designs effective and safe fitness routines using the mechanics and physics of exercise.

“Everyone talks about all the positive aspects of physical fitness, but few consider that there can be negative side effects, because our knees, hips and other joints wear out from years of use and repetitive movements. Think of the articular cartilage in your load-bearing joints, such as your knees and hips, as you would the enamel on your teeth. When the enamel wears off, it’s gone, and when the cartilage wears out, it’s bone-to-bone—or joint replacement time,” explains Weitzner, who designs personalized fitness routines after closely observing and analyzing the biomechanics of a client’s natural body movements from a skeletal and muscular perspective.

“Our joints are capable of a certain number of repetitions, based on load, resistance and direction of movement, which is basically about math, where’s there no room for opinion,” quips Weitzner, whose company slogan is, “No fads, all fitness.”

He notes that starting the latest fitness fad without consulting a personal trainer may lead to injuries. Knowing where muscles attach to bones, what each muscle does and what it can do depending upon its position, is essential for determining the type of exercises and number of repetitions the body can safely handle. “This is the best strategy for preventing injuries and strengthening muscles surrounding joints, which is a great anti-aging approach to keeping weight off joints and giving them more good years of life and flexibility,” says Weitzner, who often works with individuals with sports injuries that require rehabilitative exercises.
