okay guys,
I'm 24 years old and my weight is good. few months ago I started to lose my sex drive and the ability to endure hard works I made a lot of searches about this issue, what I found is that I have the same symptoms of low testosterone levels and I'm 99% sure that this is happened because I don't do any kind of sports/exercises, lack of sleep at night (I only sleep 2hr on avg at night) and ~4hrs after I come from my work (yah, my sleeping schedule sucks)

I plan for a big change in my life style
I was looking for the best ways to rise testosterone levels and I found out about so many exercises the problem with'em that they give you very big muscles (ya I know most men like to have really big muscles) but for me I'd really like to stick with my slim body so I was thing of a good exercises that can train your muscles and increase the stamina without having big muscles!
what about jogging?
I really think it can boost testosterone levels (but not as fast as doing heavy exercises) it just take longer time and have many other benefits
do you think I will see good results after some time if I go jogging ~3 times a week with good/healthy food program?
I plan to run ~3 miles each time, with some weights attached to my legs and hands (say 20lbs total weight)

what do you think?
to let you know, I cann't run 1/4 mile but I plan to start slowly and push my self to the limits naturaly.

I just wanna know your opinions about it so I can rise my testosterone levels, so I can have my sex drive back =(
