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.
Stronger Than Ever
You're not training to feel 25 again. You're training to get stronger than ever — without old injuries or the wrong kind of load holding you back.
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.
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.
