Need warming up exercises

I am about to start the week more tired than I ended the last one, for various reasons. The weekend did very little to me. I cannot wait for the acting class to start on Wednesday. I badly need it, for my sanity's sake. I think I mentioned once the warming up exercises we do at the beginning of every class. I think I should do them every evening, after every day of work, good or bad, as it calms me down and fills me up with energy. I don't do sport or much physicala ctivity apart from walking, but these warming up exercises are something totally out there, they have an almost spiritual effect (and I rarely use that word).
