Ok folks Ive decided to share some a tip with you guys,
I learned this after training to become a pro wrestler, I trained at Killer Kowalskis gym, but what he'd have us do is run 2 minutes walk for 3 and continue doing this for 45 minutes, its improved my stamina alot.

You're doing too much. Look up HIIT and then apply that. You will see even greater results.
