From our happy customers

It’s helped us improve the efficiency and effectiveness of our athletes training by knowing exactly how fast the bar is moving so we know we’re training not only the quality we want for the session but when an athlete is heavy enough for a strength session while almost never missing a rep. It’s also been a great addition for in-season training to guide weight selection.”
