One of the key things I work on these days is having lean muscle mass. Back when I played baseball, I had a lot more muscle (and looked damn good in my uniform I might add

) The problem is that it takes a lot more work to maintain.
So, now I run a mile every other day and stay away from sugar as much as possible. For my upper body I stay away from weights, opting instead to doing incline push-ups. The advantage of incline push-ups is that they also benefit the abs. I also do other ab exercises, but try to make sure that I change things up to "shock" the muscle.
As far as my diet, I have eggs in the morning (great energy and metabolism boost), lots of chicken during the week and red meats during the weekend(my reward), and my favorite thing of all- cabernet on a near daily basis. As some of you probably know, wine is full of antioxidants and is great for your heart. Just don't overdo it!
