Mike Mentzer believed in huge one set programs with progressive overload. High intensity workouts a couple hours a week, with long rest periods between gym date. He spoke about increasing strength leads to increased size, and the rest days being as important as the work days. This program is influenced by his technique to increase size in a 10 period to just your arms and chest. Bodybuilding focused with high intensity and small set sizes.

Common questions

Yes, Upper Body Only💪 is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 10 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.

Upper Body Only💪 is structured around 3 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 10 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.

Upper Body Only💪 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.
