OUR STORY
SportStrength began when Mark realized the huge need for athletic development in grade school athletes. Athletes were 1) not performing at peak levels in high school and 2) were not adequately prepared to step into collegiate and professional sports. Many schools lack the funding to hire a full-time Performance Coach, leaving the burden to (already overworked) coaches. So, Mark figured – why not remove the responsibility from the coach while offering the athlete training that would develop the team, increase grade-school performance, and prepare the athlete for their next level of competition? That’s when Mark ran into Kyle, the tech guru. It took one (very long) lunch meeting for them to realize what they could create… and the rest is history.
OUR PHILOSOPHY
SportStrength believes that athletes should begin participating in Sports-Performance training at a young age. This is because every kid, regardless of whether they continue in sports, needs to learn how to move properly. If they can learn this while they’re young, then they’ll have the opportunity to increase their sports performance and reduce their likelihood of sport-related injury.
At SportStrength, we do not overlook mobility training.
Do we have our athletes lift heavy? Yes. Do we have our athletes train hard? Yes. But strength and power is only beneficial if the athlete can use that power through the full range of motion. That’s why our programming consists of many supersets (pairings) of strength exercises and mobility routines. Training in this way will foster the athlete’s longevity and ensure maximal performance.
Our objective at SportStrength is to provide the athlete with the latest training methods that allow them to excel in the present while preparing them for the future.
