The Athletic Development + Performance coaches at Austin Simply Fit take a holistic approach to helping athletes succeed. This means our coaches build each athlete based on their specific needs as a human, first. Building the athlete from the ground-up no matter their skill level, creating a solid foundation and locking in the basic fundamentals of athleticism all athletes need, including: balance, running, skipping, jumping, bounding, work capacity ,endurance, strength and explosive power.

Once those skills have been mastered, the performance coaches work with each athlete to build specific qualities pertaining to general strength, reactive strength, explosive strength, speed strength, strength speed, power, and power endurance training which transfers to the field, and respective sport(s).

As former collegiate athletes and sports enthusiasts themselves, Mark and Sierra live to educate and re-educate athletes on the importance of proper recovery and regeneration methods, for all of our athletes, but especially for the young athletes and the young dual sport athletes. By teaching, educating, and putting those lessons into practice we provide tangible results through performance and recovery monitoring.

In addition to helping athletes when they are in-season, Austin Simply Fit’s Performance Coaches are experts in building off-season training to fit all athletes needs. It is our promise to help all of our athletes succeed, and part of that promise is keeping in communication with the athlete’s coaches because athletic success is a TEAM effort, and ASF is here to support the entire team’s goals through their athletes.
