Add 10 minutes of unbroken long-cycle to your engine in 30 days — without guessing pace or breaking form.
Most people swing for a minute, gas out, and call it cardio. Lock to the beat instead and you stop training random reps — you start training the sport.
The KBX Coach lays a transparent elite lifter over your phone camera. You see the bell path, the lockout and the breath cycle in real time. Match it. The metronome handles your pace. The AI debrief handles your form.

Here's what you actually get
Everything you need to train kettlebell like the sport it is.
Cadence engine with haptic metronome
8–24 RPM lock so every rep lands on the beat, even when your lungs are screaming.
Stop blowing up at minute 3.
KBX Coach technique mirror
An elite coach laid transparently over your camera — match swing path, lockout and float.
No more guessing what 'good form' looks like.
Long-cycle, jerk and snatch progressions
From two-hand swing to 10-minute long-cycle sets at competition cadence.
A clear path from zero to 24kg LC.
AI debrief after every set
Cadence accuracy, missed cues, breath drift — graded in plain English, not jargon.
Like a coach in your pocket.
Pacing tables for 5/10/20-minute sets
Pre-built RPM ladders that match your level so you finish the set, not the floor.
Predictable performance under load.
Built-in deload weeks
Programmed recovery so your shoulders, forearms and grip don't quit before you do.
Train hard for months, not weeks.
This is for you if…
- You can already swing a 16kg bell for 30 seconds
- You want long-cycle, jerk or snatch — not random circuits
- You'll train 3–5 sessions a week at home or in a small gym
Probably not for you if…
- You're rehabbing an acute shoulder or low-back injury
- You want 'kettlebell HIIT' with no structure
- You won't film a single set — the overlay is the point

"But what about…"
I'm a beginner — will the cadence be too fast?
The starter programme caps at 10 RPM with two-hand swings. The metronome scales as your engine grows.
Do I need a competition bell?
No. Any 16–24kg kettlebell works. We'll tell you when to step up weight or RPM.
What if my form is off?
The KBX Coach overlay shows the path live, and the AI debrief flags missed cues so you fix it next set.
