I am done both of my baseball seasons and I was looking to start gaining some muscle. The only problem is that I can't get to a gym until school starts, and even then I don't have weight training as a class until January. I have very little weight lifting equipment-2 lb dumbells, 3 lb dumbells and two sets of adjustable dumbells one up to 20 lbs and the other up to 40 lbs for each. Anyone have suggestions of what I could do with these weights, or body weights. Also does anyone know how much a barbell costs and where I could get one.
