Forge a body made of iron from this heavy duty, high intensity, moderate to low volume hypertrophy program. This is a classic upper-lower, rest-rest, upper-lower, rest split designed to grantee gradual gains over time. The emphasis of this program is placed on the entire body, requiring high intensity training taken to failure or 1 RIR every set. Each muscle is trained multiple times a week with an emphasis on shoulders, arms, upper back (traps and lats) and quads. Alternative exercises are given for each exercise, you have complete freedom with them (you can alternate every week, alternate when bored or in the case of plateaus, or alternate never if you please). Due to the lower volume, I emphasize the importance of intense training for ideal results with this program, however volume may be increased if recovery allows (for more advanced lifters). LET'S FORGE SOME IRON!!!

Common questions

Yes, Forge is completely free to follow on Boostcamp. Download the app on iOS or Android, find the program, and start your first workout immediately. All 18 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 80 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.

Forge 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 18 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.

Forge 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.
