Joint load, visible at a glance
Every exercise shows you exactly how much it loads your joints — and offers a gentler alternative with one tap, without losing training stimulus.
Athletic and Vital
A body you can rely on — full of strength and energy, ready for whatever comes.
Bastheon is the strength app for anyone who trains seriously: strength training that thinks with your body, not against it. Most fitness apps are built either for 20-something competitive bodybuilders — or for rehab patients. Bastheon is for you: experienced, driven, and smart enough to know that lasting strength matters more than chasing the next PR at any cost. Both deserve to show.
Your exercises, your joints — at a glance
A load rating for every exercise, a gentler alternative one tap away, and a plan that knows when it is time to back off.
Strength training that thinks with you
Automatic deloads instead of overtraining
Bastheon knows when a deload week is due and adjusts your progression before overload turns into injury.
50 core exercises, shown precisely
Clear, custom-made visuals show you correct form for every key compound and isolation exercise, including joint-friendly variations. No guesswork, no stock photography.
Mobility that undoes your desk day
Short warm-up routines target the hips, neck, and upper back that long sitting wrecks, backed by a knowledge hub on joint health and recovery. No supplement hype, no competition pressure.
Trains with you
Ready-made program or full plan builder: Bastheon adapts to your equipment — free weights, machines, or bodyweight.
Your data stays yours
Runs locally on your device, no forced login. Optional cloud backup if you want it — nothing more.
