Stop being a pussy and run. cyclings not bad but it doenst replace it. Ignore the gorilla and tabata crap too. Run, 2 miles at first, build up to 5 or 6 miles. Vary the terrain you run in, run in a park one day, run in the woods the next, run on the street the next time. I personally find nothing more satisfying than a run through the woods though. Then once you get up to runnin 5 miles , add like 2 days of sprints or hill sprints in there.

As far as running distance goes, you will learn to love it cuz you will get the proverbial runners high. Im not joking you will feel like a million bucks after you pull yourself up off the ground. Lifting may increase testosterone but i feel at best afte ra long run. So hope that tells you something.
