Smarter. Faster. Stronger.
it's you vs old you

Understand your baseline for each exercise and work smarter to hit your goals. Take advantage of those days that feel like the weight's moving easier, and play it safer on the days that it doesn't.

"Setting the right goals is good, but achieving them is more important."

athletes simultaneously is difficult.

You need to preplan the entire workout, be
lazer-focused during, and log the events post workout. The more athletes the harder it gets to focus on each athlete individually.

Calibrex 1.0 will automatically measure and analyze all your athletes performance, allowing you to focus on what really matters. Individual athlete progress.
