I've been on Weight Watchers for 10 months, and have lost about 30 lb, with another 20-30 to go. For the first 8 months or so, my only exercise was riding my bike (commuting daily and weekend rides) and the weight loss was slower than I wanted it to be. In June, I joined a gym and started doing water aerobics and lifting weights, and I started running, and my weight loss has sped up considerably.

So for me, mixing up the exercise, along with watching what I eat, seems to be the ticket.

Congratulations on your great loss so far!
