Does anyone else on here use a fitness ball or just undertake regular exercises without weights, like pull-ups, push-ups, crunch's etc.?
As a student I just couldn't bring myself to spend the kind of money the gym's wanted so I just do basic stretching every morning and every evening before going to bed. 3-4 days a week I do about 1 hours worth of work on the fitness ball. I also walk to school (45 mins. with books

each way) every day I have class and run on days I don't walk to school.
That combined with a pretty well balanced diet (I do enjoy my ice cream on these hot summer nights) seems to work really well for me. The stretching also helps to relieve any stress that has built up while sleeping or during the day so I'm usually pretty loose and relaxed.
