This program is designed for maximum muscle hypertrophy while remaining joint- and lower-back friendly, especially for lifters with a history of lower back issues. The focus is on: - Mechanical tension as the primary driver of hypertrophy - Smart exercise selection (machines, chest-supported movements, controlled ROM) - Moderate to higher rep ranges to reduce axial loading and fatigue - RPE-based progression instead of mandatory training to failure The program intentionally avoids excessive axial loading (e.g. heavy squats and deadlifts), while still training the entire posterior chain effectively through safer alternatives. Your favorite core exercises can be added to e. g. day 4. Structure 4 training days per week Day 1: Push Day 2: Lower (Back-Safe) Day 3: Pull Day 4: Posterior + Delts 6-week training block Weeks 1–5: Progressive overload (double progression, typical target RPE 7–9) Week 6: Deload (reduced volume and intensity) Auto-Regulation & Flexibility Lifters may start lighter (e.g. RPE 6–7) if needed, especially during the first week or on low-energy days On days with good recovery and joint comfort, sets may be pushed slightly harder (up to RPE 9), while maintaining proper technique. Load and effort should always be adjusted based on day-to-day readiness. Key Principles - No mandatory training to failure - No maximal strength testing - Controlled range of motion where appropriate - Progress only if technique and joint comfort are maintained This program is ideal for lifters who want to build muscle consistently, stay pain-free, and train in a sustainable, long-term manner.

Common questions

Yes, Berry's Backsafe Bodybuilding is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 6 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.

Berry's Backsafe Bodybuilding 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 6 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.

Berry's Backsafe Bodybuilding 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.
