You're showing up. You're trying. But without a clear program, expert coaching and the right data behind you, progress stalls. And eventually, so does motivation.
Most gyms throw you straight into a session and hope for the best. RTB is different. The 21 Day Strength Reset is built around you before you even pick up a weight.
We calculate exactly how much weight you lift, so you never have to think. Never so heavy you get hurt. Always hard enough to get results.
Squat, deadlift, bench and press, taught by professional coaches so you lift safely and avoid injuries.
Every session is full body and already planned. Turn up, follow the plan, and you're doing it right.
Regular testing recalculates your weights, so you always lift the right amount and always progress.
Coached strength sessions, a program written for you, and zero cardio. This is what that looks like.
Your first 21 days are designed to kick start your strength and fitness. Every member starts here.
Come as often as you like for 21 days. Use and abuse it.
Written to your numbers. The app shows the exact kilos for every set.
Classes are capped at 12, and every 21 Day member gets extra help from the coach.
Every lift logged in the app, so day 21 shows you exactly how far you've come.
