This is a 4 day hypertrophy program based on a modified upper lower split. The upper lower split typically divides your body up into upper body day and lower body day.

Upper lower works particularly well in a 4 day set-up because it’s so flexible. This modified split features biceps and some side delt work moved onto leg days to solve some of the issues inherent to the standard upper lower split, such as difficulty prioritizing the upper body and reduced performance for bicep training after back training.

Magnificent

Brandon Goff

Actually loving this program. Volume is a little high for my personal time availability, but it has good diversity and plenty of barbell which is what I enjoy.

Big work outs but great sharing on muscle group training evry week

Dante Di Lena

My honest opinion is a lot of compound lifts in the same session, if you’re pushing yourself by progressive overloading it can very taxing on the muscles. It’s pretty self-explanatory rest is everything and fuelling your body with creatine, while taking cocaine is a good way to attack this workout.

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. If you're missing something, the Boostcamp app includes substitution suggestions inside each workout.

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. As you get familiar with the program, sessions tend to move faster.

4 Day Upper Lower Program is structured around 4 training days per week, with rest days built in to allow for recovery. Consistent rest is as important as the training itself. Skipping rest days can stall your progress. The app lets you reschedule sessions if your week doesn't go to plan.

The program runs for 7 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go. Many athletes choose to repeat the program after finishing, either at a higher starting weight or with a different variation.
