In addition to bicycling/diet (WW) to lose weight I've been walking also. I've done both, but primarily cycling, for the entire year since my wife and I started WW and I like walking very much. Anybody else use walking in addition to bicycling? I go out for an hour of aerobic walking two or three times a week in addition to 4 or 5 days a week of cycling. I really don't know if it helps with weight loss when added to bicycling, though I assume it does.
