A coach who paid $60,000 to learn from an NFL trainer breaks down the method: pair opposing muscle groups like bench press with rows, then push each set to failure. This structure reduces fatigue and builds muscle faster.
I paid over $60,000 to learn this from an NFL coach, but luckily for you, you can just copy what I do. In order to get results that actually show, you need to structure your workouts properly. An example of that is supersetting bench with rows so you can limit in-session fatigue and actually push yourself to failure. Another example of that is my next superset where I did chest flies with pull-ups. Again, pairing opposing muscle groups so you can limit in-session fatigue and push yourself to failure. By now you should understand that if you pair opposing muscle groups and you push yourself to failure, that's what will get you the best results.
