Unfortunately, many novice trainers in Martial arts consider bodybuilding the same as Athletic Strength Training. As a result, bodybuilding routines are being designed for athletes by incompetant coaches. 

 Bodybuilding is not what a competitive fighter needs, functional training is far more useful. Make function a priority over muscle size. Larger muscles are useless unless they can perform in your chosen field. 

If an increase in strength is your goal, it does not have to be attained via a body building program. 

Strength is very important but do not let your training compromise any of the other essential aspect of your performance. 

Your body needs to be versatile, powerful, fast and very enduring, not just bulky.

 Each element of your training needs to have a specific purpose. Training as a bodybuilder is not going to help reach your very best as a competitive fighter in Jiu-Jitsu or any other fighting art.
