PROGRAM DESCRIPTION
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.

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

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.
