Good morning all, My sambumnim wants me to work on my Stamina. I have been shown a few things in class to work on it but I do not feel it is enough/I can do more. I have searched the forum for information on this and read many answers. What do you guys and gals suggest that I focus on outside the dojang to send my stamina through the roof? I take a bunch of supplements, I am 510 about 164 LBS. I want to really be able to work through it and not peter out, so quickly. I look forward to the suggestions! Thanks!
