Are you the average gym-rat ? Are you stuck on a plateu? Do you feel intimidated by the looming presence of this language-crazy night bird? Are fed-up how he is buffer than you? Say no more, brother. You need to change something ASAP! A 4-day split created for the intermediate gym-rat to MOGG him off of this planet. Training is focused on getting humongous treetrunks. Massive legs = massive testosterone. The upper body also gets attention and a lot of isolation work. The core, forearms and neck also gets some elevated volume to drive growth. Read the instructions on the training days. They give you clues how much effort you need to push each set. So give this program a go and get huge, brother.

Common questions

Yes, BUFFER than Duo is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 16 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.

BUFFER than Duo 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 16 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.

BUFFER than Duo 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.
