EXPLOSIVE ATHLETE

Force-plate insights · Belt-sized

A belt-worn sensor and an iPhone app that measure what actually matters — how high you jump and how fast you move the bar — live at 500 samples per second, validated against slow-motion camera. Built by coaches, proven on real athletes.

Test day

CMJ, squat jump, Abalakov, approach — full explosive profile in minutes, athlete after athlete. Hold still, GO, jump — it commits automatically.

Game & practice

Wear the belt and just play — every jump counted and measured. Jump load and heights for the whole session, no buttons pressed.

🏋

Weight room

Bar velocity on every set: training zones, velocity-loss auto-stop, bar path — and explosive metrics almost nobody else measures.
