I think this is the key. No matter your age, recovery is AS important as training. If you can find a way to get it all in and still get enough recovery time, then go for it.
I would *like* to weight train year round, but frankly, I don't have time. For me, it's not about my body not being able to handle it (I don't think)...it's just that during the summer, there is just too much to do!
