Do you want mass? Because this is how you get mass. Long time 531 classic with periodization Bible as my go to. This is a nice change of pace and an excellent way to challenge yourself. I superset everything I can for the sake of time, and that turns it up some. Good luck.

I had been doing 531 BBB for sometime before finally getting "bored". This program is challenging and requires significantly more focus, energy and time. The results have been great and I certainly gained more muscle mass than I expected. The only modifications I made were for the conditioning portions, I used my rower instead of the AirDyne bike. Otherwise, great program for pushing anybody stuck on a plateau or looking for something challenging.

I would definitely recommend this program to anyone looking to kick their strength gains up notch or two. Be prepared to work past the point you're ready to quit! That's where the gains live.

Great program, challenging but doable. Changed dips to weighted version but came back to bodyweight dips as they arę better for my shoulders and elbows

I love the simplicity, the progressions and the exercise selection of the program. The percentages on the compound lifts are spot on. I have already recommended this program to a friend that is a fan of Jim Wendler’s 5-3-1 program. I have gained roughly 3-5 pounds of muscle and dropped a noticeable amount of body fat. My strength has increased on all the compound lifts, especially my Overhead Press. My plan is to run back through the program again, for another 6 weeks. Love this program!!

Swapped some of the ohp for incline bench, and added some weighted dips. 2 of the 4 weeks I swapped sqats for legpress
