Sorry for leaving this out. My circuit routine consists of using equipment I have at my house Dumbbells, Curl Bar, bench, stairs. I realize that machines are a no no. I have been slowly increasing weigts on the dumbells and curl bar. I also realize that eventually, if I want to keep growing, I will have to get a gym membership. For now, for financial reasons I am working with what I have and doing as many exercises that I can with 2 dumbbells and a curl bar and a lot of weight. I understand where you are coming from and appreciate your comments.
My main concern is: Do you think I am hindering the recovery process by running on my off days or should I be just sitting on my ass? Just a question about recovery.
