I need more exercise. Unfortunately I'm too skint for the gym or classes, but I do have 3 free mornings a week when DD is at nursery and a large park nearby.
What's the bare minimum I need? I figure running shoes, sports bra and top with zip-up pockets so I don't lose my phone and keys. Where's a good place to buy these?
Also, any general tips? I don't think I'm horribly out of shape; I walk 2-4 miles most days and I walk fast, but haven't done any proper running since I was on the cross country team at school and I'm 38 now 
TIA!
