It seems that I'm having some trouble getting out of a rut. I train very regularly and it seems that I have reached a plane in weight and in endurance. I'm having trouble losing that oh so dreaded "last ten pounds" and when it comes to endurance it seems that no matter how hard I try I can't break my mileage goals. I always try to vary my workouts and vary my speeds, I also cross-train with other sports to break repetition in muscle use and my diet is very good. Should I be cutting back ( like a slim-fast diet or something? ) or trying to go more and pushing harder with my workouts and rides? Thank you for any help in this matter.
