Got my goal of Benchpressing 40kg again! and for 3 reps! overall great program but the 10 reps for squats and deadlifts feels like cardio ngl

Loved this program. I did the 4 day version and consistently improved my strength PR's and have the most defined muscle I've ever had in my life. I did however start to get bored around week 10/11 but that was near the end and I could've done more T3 variations but I was crunched for time.

A simple program to follow with great results even with going only 3 days a week. After about a year of consistent gym going this felt like my first proper lifting program. The progress keeps me really motivated and I have noticed huge improvements in my strength. At the stage where I hit a new PR every session, I'm hooked.

Great program. Really good balance of strength and hypertrophy that works for me. Swapped the T2 exercises for variations just because I wanted more variety. Went with SSB Squat, Close Grip Bench, Romanian Deadlift and Incline Bench Press. Swapped T3 chest exercises for bicep curls as I had enough chest focus in my T1 and T2 and felt my arms were lacking. Other T3s are Upright Row, Bulgarian Split Squats and Hip Thrusts.
