02 / THE PLAN

It remembers. You lift.

Your plan knows what you lifted last week. Each session picks up where the last one ended. Just get your weights ready.

Fixed rules. No guesswork.

When it suits you.

Three times this week, when it suits you. No fixed days. Missed a session? No need to catch up. Just carry on.

No catch-up sessions. No guilt.

YOUR NEXT SET IS READY.

Not your plan.

No choosing exercises. No remembering weights. Open your workout. Get your dumbbells ready. Start.
