Thanks for the theory about each athletes cos I too have been thinking about how they train to get their physics. I was training the usual one body part a day for the last 3 years. Got stronger and bored of the same routine. So I now do full upper body a day and lower other days. Friends at gym started questioning me about it in doubts. But now I have a real theory to answer back. I always want biceps like a gymnast?. Just to try something different do you recommend doing one body part for one week then another the following week and so on?..
