Really good program that's flexible, it's nice every week to get a PR in either weight or reps

I joined the gym for few months and I was changing my workouts alot and trying different exercises so often because of the lack of knowledge and that made me stuck in progression. And then I decided to start this program, at first I was afraid of the T1 exercises with the heavy volumes and the exercises especially the Squat and the deadlift because of what I hear about how dangerous they are. Since I am not training for competitions I tried to change some exercises, so I changed the conventional deadlift for the trap bar deadlift, and also changed the dumbbell row for a chest supported tbar row, also because in our gym the smallest weight that you can add is 2.5 kg plates, it made it hard to progress as mentioned in the the bench press and ohp so sometimes I try to add more reps in the AMRAP sets while keeping last session weight. I liked this program because of it is simplicity but also effectiveness, you have rules that will make knows when and how to progress and also the amount of confidence that it gives you when you see you are progressing in both the strengh and the muscles even thought I am not in a strict diet and trying to be in a caloric deficit.

Gained 5kg in 3 months. Some muscle groups are not trained enough but it's okay. (Neck, abs and lower back)

I started at the gym just doing my own exercises and that helped me get used to things but I ended up reaching a plateau in terms of strength gains. But switching to this program really helped! This program has been great for consistly building strength.

Stick with the program. It works. Figure out best days to add bi’s, tri’s. Extra delt work and calves. Doesn’t extend session to much. Follow the plan and you will see results rather quickly

I haven't really lifted weights heavily since high school. I'm 38 now. Naturally strong and bulky but I've been feeling myself getting weaker and weaker over the years. Decided to try this program to help me have a target each day in the gym rather than winging it. It helps keep me motivated because I don't have to think too hard. My goal is to hit the 1000 club in 6 months. I'll tell you, this program has me getting my strength back so fast. If you are like me, I recommend starting lower weights than you think you need and focusing on form and slow calculated movements. Before you know it you'll be getting PR's every week! Good stuff. All I changed was that I added a calf workout on half the days and an ab workout on the other half.
