Our go_exxentric #kBox3 was lonely so we got her a friend. We're very excited to welcome our new #kBox4 as the latest addition to the #AthleticLab #exxentricfam today. The updated version of the #kBox has some fantastic upgrades that'll make it even more useful as a training tool. We use the kBox for training and testing. There's no better device on the market for achieving an #eccentric overload safely and effectively than the kBox. It uses #flywheel technology coupled with real time feedback via the kMeter that allows athletes to train in an unlimited number of movements with an eccentric overload that would be nearly impossible to achieve safely through traditional mass-based (free weight) loading. #strength #squats #weightlifting #power #sport
