I'm so unfit. I tried to do some sit ups earlier and felt like throwing up. I think I managed 3.
I can't run. I'm 5'7 and 12 stone so a bit overweight but not massively so. I just don't exercise. I try to walk when I can but with kids and work it's not very often. Im pushing 40 and feel like if I don't try and improve things now it will just get harder and harder.
So where do I begin? Help!
