Enjoy! WEIGHT PROGRESSION- aim to add 5-10lbs every week on main compound movements (deadies, squats, OHP, bench) For isolation movements, try to add 5lbs. Once you stall, focus on form and rep quality. For movements with rep ranges, go up in weight once you can hit the upper range of reps for first two sets. Example: 3x8-12 1st set: 12 reps 2nd set: 12 reps 3rd set: 8 reps. REST- Take at least one day off between full body days and do arm day the day after day 3.

Common questions

Yes, 3 Day full body + 1 day arms is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 12 weeks are fully unlocked.

This program is built around a garage 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.

3 Day full body + 1 day arms is structured around 4 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 12 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.

3 Day full body + 1 day arms 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.
