Perfect form is the most important thing to have a perfect body, it's impossible to make a painting with a big brush
Eat a lot and train hard, I am sure that you will succeed.
To be a good bodybuilder you must be a good observer.
I do for one full hour non-stop of 2,000 sit ups and then 6 sets of leg rise.
Yes it is better to keep training even if your muscle is still sore.
Bodybuilding is not only a sport but first an ART.
