A belt that measures jump height, takeoff direction and bar velocity — and records your games on its own. No subscription.
Plain numbers from a belt on the waist or the sensor strapped to the bar. Jump height comes from flight time, checked against slow-motion camera. Nothing is estimated from a formula you cannot see.
Charge it over USB-C. 20+ hours of use on one charge.
Explosive Athlete is free on the App Store and Google Play. No subscription; an account only if you want cloud sync.
The belt on the waist for jumps, or the sensor strapped to the bar for lifts.
Switch it on and it appears in the app over Bluetooth. No hub, no Wi-Fi.
Stand still, then jump or lift. The number is on the screen as you land. In a match, leave the phone in the bag — the belt records on its own.
Any phone charger. 20+ hours of use on one charge.
It blinks while it waits, holds steady once the app is connected, and blinks twice when there are jumps stored on the belt.
One slide, on. One slide, off.
26 mm, one on each side. The elastic belt threads through for jumps; the same slots take the strap on a barbell.
34 × 46 × 14 mm · 26 mm strap slots · USB-C · Bluetooth · 20+ h usage time
Free on the App Store and Google Play, no subscription. It works with the belt, and it works as a training record without it.
Height, flight time and takeoff velocity from every jump, validated against slow-motion camera. Each jump also gets a takeoff direction — standing, lateral or approach — and its horizontal speed, so a spike approach and a standing CMJ are never mixed up.
Strap the sensor to the bar and every rep gets its velocity. Each rep is compared with your last session at the same exercise and load, so you see on the spot whether today is faster or slower.
For cleans and snatches a rep is the dip and the pull, ending at the catch. What happens after the catch is ignored until the bar resets, so the rep count matches what the coach sees.
Wear the belt in practice or a match with no phone nearby. It records every jump on its own; afterwards you connect and import them with one tap.
A coach account links to athlete accounts. The coach sees the whole roster and pushes programs; the athlete sees their own program and results. Everything syncs between the two phones.
Every test and every set lands in History, grouped by session, filtered by date, athlete or exercise. Open a session to see the jumps or reps inside it.

Strength and conditioning for volleyball and basketball athletes — every program starts with a real test of your jump, speed and power. Built in professional sport. Delivered online worldwide.
We identify your key performance indicators — the measurable physical abilities that directly impact your match performance. Numbers, not guesses.
We compare your data against position-specific benchmarks. This tells us exactly which physical qualities are limiting your on-court performance.
Your program is built around your weakest numbers. Every exercise has a purpose. Every session moves the number. The scoreboard notices.
I'm a strength and conditioning coach with experience across professional clubs and senior national teams at European and World Championship level — volleyball and basketball, from CSKA Sofia to Champions League qualifying with Azerrail Baku and the Azerbaijan Men's National Team. My background is unusual for a coach: an MSc in High-Performance Sport and a BSc in Statistics & Social Research. Data isn't a buzzword in my training — it's my first degree.
The method was born from professional necessity: when results are measured in wins and losses, training must be measurable too.
Every program is built on your own test data — never a template.
8-week structured training plan targeting the qualities that decide explosiveness in your sport. Designed for team sport athletes. Fully guided, fully online.
Submit your test videos. I analyze your results against professional benchmarks and deliver a full written report with clear training priorities.
A full assessment followed by a custom 8-week training program built specifically around your identified weaknesses. The complete method.
My vertical went from 58cm to 67cm in one 12-week block. For the first time I actually understood why every exercise was in the program.
The assessment opened my eyes. I thought I was fast. The data told a different story — and the program fixed it.
Training finally made sense. Every session had a purpose tied to a number I could measure. My RSI improved 18% in 8 weeks.
