Really helped me kick start my weight loss. With this regimen and minor calorie restriction, I managed to lose 15 kilos in just over two months

Started this program after a long hiatus due to injury. I love the meat and potatoes approach with optional accessories. The progression is easy enough as well. If you're looking for a simple and effective program no matter your experience l, this is a great choice.

Excellent program. Made significant gains on lifts. Enjoyed that it was 3-4 days a week, fit into my schedule perfectly. Will most likely run this program again. Highly recommend it!

The optional sets likely make a big difference. Usually was doing more weight or more sets than prescribed on the recommended lifts but saw average/modest strength/endurance gains.

Great program for beginners who are looking to increase strength & muscle without too much knowledge. You learn all the basic exercises and target most muscle groups. Made no modifications and got great results. Will keep repeating it in 12-week increments. Would recommend.
