Why you should never be sore after training

Firas has trained some of the best fighters in the world, including Georges Saint-Pierre, former UFC welterweight champion, welterweight contender, Rory MacDonald, and many others. Some of the best mixed martial artists from all around the world come to learn from him. He is known to have a very philosophical approach to training.

To me, the sign of a really excellent routine is one which places great demands on the athlete, yet produces progressive long-term improvement without soreness, injury or the athlete ever feeling thoroughly depleted
