Train yourself. Backed by a real coach.
Every time you open J90, your workout is already built — around the equipment you have, the muscles that are recovered, and the weights you lifted last time. And when you have a question, a real person answers.
$25/month
No contract. Cancel any time.
A fresh workout every time you open the app
No fixed calendar to fall behind on. Open it, and today’s session is already built.
Built around your equipment
Home setup, full gym, dumbbells only, or just bands — you only see lifts you can actually do.
Knows what you trained yesterday
Sore muscles get a rest; fresh ones get the work. Weights are suggested from your own history.
A real coach, not just an app
One check-in from Jay every month, plus 3 questions you can ask any time. Ask Jay answers everything else instantly.
