This program is about building strength, confidence, and discipline side by side — not chasing perfection, but showing up consistently. We train together to learn, to support each other, and to stay accountable, while still respecting our individual goals and limits. Every session logged is proof of effort, not comparison. The goal isn’t just how we look at the end — it’s becoming stronger, more capable, and more disciplined people through the process.

Who it's for

Beginners new to structured strength training
Athletes focused on building muscle size
Athletes who can train 5 days per week
Athletes with access to a full gym (barbells, dumbbells, cables, and machines)

Common questions

Yes, The Great Lock-In is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 18 weeks are fully unlocked.

This program is built around a full gym. Make sure you have consistent access before starting, since the progression model assumes you can perform the same movements week over week.

Each session typically takes around 60 minutes to complete. That estimate covers your working sets but doesn't account for warm-up or rest between sets, so budget a little extra time when you're first learning the movements.

The Great Lock-In is structured around 5 training days per week, with rest days built in to allow for recovery. The Boostcamp app lets you reschedule sessions if your week doesn't go to plan.

The program runs for 18 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.

The Great Lock-In is available inside the Boostcamp app, free on iOS and Android. Once you download the app, you can search for the program by name. The app tracks all your sets and weights automatically, so you always know exactly what to do next session.
