thanks man..its stuff like this i like to hear..peoples real experiences...some things sound good in theory but dont work so well in real life
I've trained bodyparts twice a week for nearly 15 years. It's worked well for me.
The reason bodybuilders use splits is simple. As you become stronger, it takes more stimulus to increase your strength and size. If you try to train your entire body, more often than not, there'll be one bodypart that you'll train with more effort. Once you're spent, you'll go through the motions with the rest of the bodyparts. For too many guys, it's the legs, that get the minimal effort.
I made my split simple: Upper body (Monday & Thursday); Legs (Tuesday and Friday). Furthermore, I don't train to failure, which allows me to train with more volume. As long as you can recover from your training, you'll make progress.
