Annoyed at myself for putting some weight back on I had lost . Time to attack with exercise. Which would be better for weight loss for someone who is currently quite unfit - a Fitbit (I tend to walk a lot anyway but thought challenges might help?) or one of those Smart Hoola Hoops that keeps popping up on my Instagram feed? It has links and you clip it around your waist and it has a weighted ball on it. Thanks for any advice!
