Gaining weight and internal martial arts
I'm 6'4" and 166 pounds. I'd like to gain about 15 pounds and be around 180, so I've been researching weight gain. It seems like a high protein, low fat diet with an increased caloric intake will do the job, but all plans include weight lifting and reduced cardiovascular activity. It seems like this is contradictory to the practice of internal martial arts, since increased muscle mass might inhibit flexibility. Has anyone lifted weights while practicing internal martial arts? any recommendations or advice? I know this has been on here before but the threads are gone now with the new setup.
Thanks
