Hi, Over the last year I've been trying to get back into exercise after putting on some weight and having long weekends. I took up QiGong from DVDs and practice a few times a week. I'm currently trying to make it a 5 days a week habit. My question is, should I practice CardioVascular exercise as well as QiGong to get the best benefit? I'm not entirely unfit but doing running etc feels quite strenuous to me at the moment.
