I work in a job where I sit all day, but I walk 2 miles (up hill) each day, swim once a week(18 laps), and take a Pilates and Yoga class once a week. I've been doing this for half a year now (except for the swimming, started that when summer hit), but I see no change in my legs. It's still flabby and the cellulite areas don't seem to be going anywhere. Any good suggestions of how to lose fat on legs? I can't run because I've got a strained knee. Any suggestions would be greatly appreciated!
