Without getting subjective, you can’t improve what you don’t measure. This is why at Athletic Lab we make a point of testing and cataloging performances in areas that are most relevant to an athlete’s sport performance. We stand by our ability to QUANTITATIVELY improve an athlete’s strength, speed, stamina, jumping ability, or any other capacity important in that athlete’s sport. Be wary of trainers or training facilities that promise improvement but don’t measure progress or don’t use tests that are relevant to your activity.
