Really good program and more importantly you can complete it with minimal equipment. It never felt too boring because of the two optional exercises in each session.

It's a good program as it allows you to progress different sets and rep schemes for the same exercise, so you can track weight independently. The rules are hard to follow, especially it is not defined what a fail means and how to continue properly. I'm going to run it again, but I basically split each session in two days, first I do the T1 and T2 exercises, the next day the rest, that works evst for my body.

Great straightforward progressive program. I enjoyed the tiers and the dropping through sets to resets. I'm 50 yrs old, so only modification was that I only went down to 6 sets of 2 with no issues. Will be adding this prog to my rotations.

I've started working out on and off past 9 years numerous times. Never stuck to it cause I lack that discipline and life got in the way too. Somewhere along the line I picked up like 90 pounds of weight and a herniated l5 s1 disk. However back hasn't given me problems past couple of years and I had already began training under a different program (Dorian yate's routine) so I decided to attempt powerlifting training again. Has been going great so far. Strength stacking up from workout to workout. Some marginal modifications were swapping rows and pulldowns cause rows on deadlifting days scares me cause of my back. Other than that I've added couple of sets in t3 for some "bodybuilding" muscles such as side/back delts, biceps etc.

I like this program for its flexibility and its built in progression for failure as well as its two pronged approach to strength gain. Strongly recommended to any beginner.
