I've been trying to lighten my horses load too. I've been walking. I wear a pedometer and my goal is 10000 steps. The other day I was doing mostly desk work. I don't know if I wasn't moving much or if it wasn't counting but I only had about 400 steps recorded. I forgot to take it off before riding. I noticed whem I got off I had almost 5000 steps:')
Heh... I don't think those steps count ;~D
