I tried to hit a couple new PRs every week for upper and lower body, and twice a week I added 10 mins of Pilates at the start. This is the second time I’ve done the program and I’ve increased my max rep weight by 40ish lb. Will be doing this program again for sure.

Good all around program to help remain consistent (consistency is key). Only thing I don’t like sometimes is doing a little too many lifts with just 2 sets (personally prefer more than 2 as switching exercises gets annoying).

Would definitely keep coming back to this program just as long as you bring the effort. Gained strength and some size.

Si lo siguen al pie de la letra y se trabaja en los rangos sugeridos de 1RM y en la RPE al 8-9. Se tendrán buenos resultados.

He probably spend 30 minutes making the program. A third of exercises are unnecessary and make you look like a idiot.

Great program for breaking my strength plateau as lifter who’s focused more on hypertrophy. The explosive lifts are the key for me. Saw strength gains every week which is rare having lifted consistently for almost 5 years. Only modification I added was some ab work after upper days.
