Well I want to be a receiving tight end for football, I'm 15, 5 10" and weigh about 195. My coach says I have great hands but I need to get faster ( I can run a 40 yard dash in about 6.5 seconds) besides losing some weight which will obviously help, what else could I do ( I know it's not football season, that's what he told me last year and I thought I should start training now.) oh and I'll be a sophomore this upcoming season.Well I want to be a receiving tight end for football, I'm 15, 5 10" and weigh about 195.

Cut off your arms. The saved weight will make you a lot faster.

start running 5k or 2 miles a day helps a lot and should take less than and hour FOR SURE. If you do that you should be in good shape, you could also lift weights, snag balls, cross train by playing other sports in the offseason to stay in shape too.

Running is both physical and mental, if you are mentally strong then you'll be able to become faster through the physical part of training yourself. Basically, you should make a goal for yourself, say.. a certain time to travel a certain distance, and from there just build up. When you're tired, that's when you try your hardest :P
