Everybody knows that going to the gym can have an effect. We've all seen the Body Builder and the such or the Aerobics Instructor. Yet many people go to the gym for years and experience no major changes.
On the one hand people say "I don't want to be a workout fanatic, I want balance in my life". On the other hand people cling to various excuses, like bad genetics, and others.
Resistance training with body weight isn't different than the gym in this regard. If you are not willing to make the lifestyle changes to support the practice, giving all that you got, don't be surprised if the years go by, and you spend countless hours in the gym watching other people tone up and getting stronger while you stay the same.
It isn't a matter of fanaticism, or even of balance in life. It is a matter of the scientific effort it takes to get results. If you are not willing to make a change, extend a real effort, make a sacrifice, then don't be surprised and don't look for excuses when you get 10% of the results possible from your form of training.
It does take sound nutrition to succeed, since love by itself is not sufficient in providing all the building blocks of a healthy body for most people.
If you are willing to spend hours training, be willing to make some dietary and lifestyle changes to support it.
It is a very important path, taking care of this body you were given tends to change peoples perspective and appreciation for other things and improve the probability of a satisfying lifetime.
People now days want to do less for themselves and get more. Nothing wrong with being efficient, but how about doing that and doing more.
Find a path that makes sense to you, and follow it with all that you got, holding back on it, is holding back from yourself. Give it your whole for a few months, then look back and ask yourself if it was worth it. Most likely you will just dive back in harder.
