This is a great program to follow on our own if we have some training experience. Thanks Boostcamp for providing an easy way to track

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
