But if I start running three times a week for 30 to 45 minutes and I do this pretty consistently on the days I don't weight train, I find that I start to crave it. It's almost as if my body needs that in order to, I always say, clear out the cobwebs, but it's like my mind doesn't function as well, clearly now I understand why and why exercise helps, but also physically I almost feel like my body needs to engage in that movement.
