First time doing a program of this style (full body) and it’s worked wonders for practicing the main lifts and has blew up my quads and back compared to any other program I’ve done.

I used this as an experienced weight-lifter to recover from surgery, and it did a great job. Gradually bringing me back from 30% of pre op weights to about 60%. And growing!

Currently on Day 3 Week 12, this actually added +50kg to my lower lifts and +30kg on my upper lifts. Progression is good, it is satisfying to see the numbers go up every week, the protocols are good and easy to follow, i followed what the app said but on my next run I'll switch things up, that's why this is good because it is also flexible on your goals. Overall good program 👍

Great program for linear gains. Worked it until I stalled repeatedly and now am moving to a more intermediate program. I'm happy with my gains. Only had to modify a couple exercises due to having a garage gym which was easy to do.

This is such an intelligent program, especially for the novice level that still benefits from linear progression.

This is the best program I’ve found for flexibility- as someone who doesn’t always use the same gym and with varying equipment available - also if something goes in the way one day it’s easy to pick up again the next day an doesn’t throw off the entire week of training

I am almost done with first cycle, and will be breaking previous prs for all 4 major barbell lifts.

I’d recommend this to get back into weightlifting. This takes the perfect amount of time to do and allows for progression to happen!
