This is a 6-day hypertrophy-focused training program specifically designed to maximize glute and quad development while maintaining overall muscle balance. Built with a smart blend of strength-based compound lifts and glute-focused isolation work, it delivers high-volume stimulation across your lower body, with a strategic emphasis on glute activation, mind-muscle connection, and controlled progressive overload. Upper body days are designed to enhance shoulder and back aesthetics, ensuring proportional development while supporting your compound lifts with strong, stable posture and core engagement. Each week includes a dedicated cardio/recovery day to support fat loss, promote active recovery, and improve cardiovascular health without interfering with your muscle-building goals.

Common questions

Yes, Main Split is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 14 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.

Main Split is structured around 6 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 14 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.

Main Split 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.
