Bulletproof your shoulders and unlock pain-free overhead in 21 days — using a single steel mace and your phone.
If you can't lift overhead without pinching, you can't train hard. The mace builds the shoulder you wish you'd had ten years ago — and the KBX Coach shows you exactly how to swing it.
Mace work is all about controlling a long lever behind your body. Get it wrong and you tweak a shoulder. Get it right and your overhead opens up, your spine decompresses, and your conditioning gets a free upgrade. The overlay shows you the arc, joint by joint, in real time.
Free tier included. Pro is £11.99/mo or £99/yr. Cancel anytime.

Here's what you actually get
Everything you need to train mace like the sport it is.
KBX Coach swing arc
See the 10-to-2 path, the 360 deceleration and the squat-press chain laid over your body.
Mirror, not guess.
Breath-led tempo engine
The metronome breathes with you — inhale on the load, exhale on the swing.
Slow it down so you can actually feel it.
Shoulder-safe progressions
From 7kg pendulum to 15kg squat-press chain. Every step earned, none skipped.
Mobility that holds under load.
AI debrief on path & deceleration
Where you lost the arc, where you rushed the catch — graded after every flow.
Fix the rep tomorrow, not in a year.
Flow chains for conditioning
Two-handed combos that drip your heart rate up without slamming joints.
Cardio that doesn't wreck you.
Mobility audits every 14 days
Range-of-motion benchmarks tracked over time so you can prove the progress.
See the shoulder open up.
This is for you if…
- You feel a click, pinch or 'limit' overhead
- You sit at a desk and want shoulders that survive it
- You'll train 3–4 short sessions a week
Probably not for you if…
- You want a one-rep-max PR programme
- You won't mount a phone where you train
- You're in active rehab without clinician clearance

"But what about…"
I've never touched a mace — is this safe?
The starter programme begins with the 10-to-2 pattern at 7kg, breath-paced. We progress only when the AI debrief shows clean reps.
Will this replace my main training?
No — it slots in as a 15–25 minute mobility primer or finisher. Most members run it 3–4×/week.
What if I have a dodgy shoulder?
Get clinician clearance first. The overlay won't fix an injury — it will groove the movement that keeps you out of one.
