Tomorrow i have a full day of nothingness, so i want to exercise (i love exercise). It's supposed to rain, so i can't go for a run or cycling. I don't want to go to the gym, because i'm going on monday and the swimming pool is only open until 12pm. I don't want to do just sit ups, push ups etc. i want to go cycling, but not if it's raining. I don't have any equipment at home and there aren't any fitness classes on tomorrow. Any ideas? List as many as you can think of please.
