This is my secound time on Atkins and this time I am very active. I swim almost every day and I walk maybe twice a day but once for sure. Does any one else do this kind of work out and if so how is it going for you ? I am trying to get out of the running thing because of my knees I have done 9 years in the Infantry and it has taking a tole on the knees. Is swimming a great whay to drop the pounds ? I know it is good for you but I need to lose the weight ?
