I don’t know how you train but the fastest I ever dropped bf was running Meadows Onslaught routine. It was brutal and I know people say we don’t burn a lot of calories working out but I had weight dropping fast on a cut I could very clearly see weekly changes from week1 to week12. I did no cardio, took no fatloss drugs and I wasn’t running crazy gear. It was 400dhb 200test. I’ve done it twice with Meadows programs the other time I did his Gama Bomb program. I was burning through everything I ate.
His programs are great for older guys who love to train hard but need more intelligent programming.
