PowerSource Performance Fitness & Barbell Club

When Sydney came to PowerSource, she found something different from a typical gym — an environment built entirely around getting better, with no room for distraction.

Since then, her training has been driven by data. Her strength, speed, and explosiveness are measured, trained, and retested — not guessed at. The result is real, measurable progress she's carrying straight into competition.

Sydney is one of our PowerLab athletes, and the same custom testing and program design behind her progress is available for every sport and every age. Wrestling, Football, soccer, volleyball, softball, track, or anything in between — we build the plan around what your athlete's numbers actually say they need.

Kneeling sprint starts = first-step power.

In softball, the first 2–3 steps decide everything:

exploding out of the box

getting a better jump on a steal

winning the first move to the ball on defense

Starting from the knees takes away momentum and forces true power + projection from zero—so every rep is about intent, force, and getting to top speed faster in short distances.

The same is true for any sport that lives in those first few explosive steps—football, soccer, basketball, hockey, lacrosse, and more
