Great combo of strength and hypertrophy. I like the fact that they have exercise options which I used to work around injuries.

First time trying a powerlifting program. My goal was to rebuild some of the strength & muscle I lost after undergoing cancer treatment last year, and I more than surpassed my wildest expectations. For reference, female, 47, 5 ft 2 in, 120 lbs, home gym. Bench 5rm 75 to 90 lb, ohp 5rm 40 to 60 lb, squat & deadlift maxed at 115 lb because I need to buy more plates! Stopped after 9 weeks because of another surgery, will absolutely run the program again in the future.

I’m on my 5th week of this program and I’m loving it. I like the full body concept 4x a week gives me time to focus on cardio/core on off days. I add biceps,leg curls,leg extensions at the end of the workouts. My legs have blown up from this program highly recommended.

Great program for novices and especially for those returning to lifting after becoming detrained.

Perfect program for me as a complete beginner. I had an experienced friend show me the 4 main lifts, and then I built upon that. Just finished week 10, I've seen huge improvements especially in deadlift (205lbs from barely 90 at the start) and overhead press (105lbs from barely 45). I love how easy it is to use I added some biceps/triceps/calves/abs throughout the workoutd as they are really not that targeted in this program. I go every other day, but with the progression I've done, I have to do only 2 set of the leg or squat exercice every other training to get proper recovery

I would recommend this program. I liked the program a lot. I made gains each of the twelve weeks. About 8 weeks in I went to every other day instead of 4 days a week. At about the same time I cut the work outs to 60 minutes by only completing tiers 1&2.
