I just started working out at the beginning of this year, I never wrestled or did any martial arts before. I am 31 years old 6'4" and I started out at a weight of 262 pounds. I am 5 months into working out and I am 232 pounds, I started running and by the way I have allways hated running and have not run before now since I was a sophmore in high school. I am currently running about 3 miles when I run about 3-4 times a week, my other workout consists of boxing, kickboxing, and BJJ. My question is how many miles do you or should you run a week. I am working out to lose weight and a little rehab other than that for fun. I could never fight other than maybe a boxing match because I have a steel plate in my left humorous and I have had a cervical fusion in my neck C6-C7 with a steel plate there. My other question is, is ok to run slow if you are going for long distance then do a sprint for the last 1/4 mile or so. I also would like input on trail and hill running. Any help would be great. If this is a continuing thread I am sorry I am pretty new and this is the first thread I have ever started.
