Need to get A NEW shape.....

I already have a shape so I don't need to get in shape, I just need to change shapes. d:{)>
I was out playing basketball in the driveway with No.'s 1 & 3 sons. and got beat 10 - 11. That's not the important part here. No. 3 son is 7 years old and was a LOT less winded than I was. I'm only 35 and you'd think I would be in decent shape. I didn't do alot of sports in school back in the day but I did exercise. Since I've been playing softball with the church and some basketball with the son I think I've realized I need to get back into exercising and finally get that MANLY figure I've always been wanting. d:{D>
Anyway, my goal is to play to 11 with my son and not fall over from lack of oxygen. Also I'd like to make it around the softball bases the same way. Maybe I could even make it to second base on my hit by being able to run faster... I don't know. Just wishful thinking probably.
