Coming to the App StoreMaintenance for your hardware.
Jiu-jitsu is fun, addictive and great exercise, and it beats people up. The fitWrench Suite is everything that keeps you on the mats that isn't technique: fuel it, maintain it, measure it, and train the mind running it. About 15 minutes a day, from a black belt who's barely missed a day.
Hardware belts
You're a black belt on the mats. What belt are you at taking care of your body?
Every pillar has its own belt, earned by showing up: days logged, sessions done, recovery respected. Your hardware belt is your lowest one, so the weakest link shows.
Earned slowly, over months, like the real thing. Consistency, not intensity.

Example

Engine
Mind
Hardware belt: white, 3 stripes. The engine is the weak link.
Four pillars. One subscription.
Each app does one job, and they make each other smarter. Recovered today? Your session goes harder. Logged a hard roll? Recovery and refuel come up next.

Why listen to me
Black belt. Almost no injuries. Barely missed a day of training.
Most people don't survive jiu-jitsu. They get hurt, take a month off, then another, then stop. I made it to black belt with almost no time off the mats, because looking after the hardware was priority number one, not number 24.
The suite is the system I use, turned into apps.
