Mass JYM Study Program Overview

The training program you'll follow during the Mass JYM Study is designed to promote lean muscle mass gains – gains in muscle size accompanied with fat loss. This program and the Mass JYM Study diet both need to be performed as written.

The training program is a split-body routine where each major muscle group is trained once a week over the course of four days (4-day training split).

The Mass JYM Study is a 6-week experiment, so you'll follow the program for six weeks – 24 total workouts.

The training program is basic by design; this is not a time to experiment with new training styles, as the purpose of the study was to test the Mass JYM formulation.

Feel free to use comparable variations of the exercises listed below. Just make sure the exercises you select are the same basic movement as that listed. The important thing is that you follow the same training volume for each muscle group that's listed below (total number of sets) and stay as close to the prescribed rep ranges as possible. You should be reaching failure on a given set in the rep range listed.

What days you perform the workouts can also vary. The below split shows training days as Monday, Tuesday, Thursday, and Friday. You do not have to train on those exact four days every week. Choose whatever four days work best for your schedule and allow for the best possible workouts.

You'll perform three sets of each exercise (listed below) and take 2-3 minutes of "active rest" between all sets.

The "active rest" refers to cardioacceleration – the form of cardio you'll do during the Mass JYM Study training program. Cardioacceleration involves doing 60 seconds of any type of intense cardio activity in between sets of resistance training exercises – for example, running in place, jumping jacks, burpees, etc. (To learn more about cardioacceleration, read this article .) Between all sets, do the cardio activity for 60 seconds and rest the remaining 1-2 minutes.
