Good program stick it out and use the notes reminding you what to do when you hit your target. Very nice program. Got stronger quicker than I’ve done before.

Easy as long as you take the time to learn the program. It seems intimidating at first, but you will learn fast

Great program to get back into lifting. Can knock it out in 40 mins. Switched squat and deadlift for hack and trap bar.

Good programme. I think I'll do another 12 weeks before trying something different. My main issue was the length the session takes, particularly as you get later in the cycle and lifting heavier, so I had to cut out nearly all T3s from weeks 10-12. That's just a personal thing, nice programme though and I made some great strength gains.
