I have been using this model for the past 4-5 weeks and i find it really really great. I started with conservative weights and every week I add 2.5 kg and i am astonished everytime that i am able to lift heavier. I am really thankful to the developers of this program and this amazing app where you have so many options even with the free version ❤️

Nice program for strengthening main lifts, did not see much muscle growth, but did see muscle toning from the to-failure exercises. Be conservative on your starting weights, you will see progress.

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.
