I went through 4 sets of ankle weights, and they all broke so I decided to get the vest. $129.99 at amazon. The best thing about the vest is that it is a shortened vest. So I have full abdominal use and can do sit-ups and crunches with the vest on. All the reviews for the vest are 4 and 5 star reviews. They also sell a full vest that is like 89 lbs I think. That is a bit to heavy for me to run with tho. Maybe for hiking/road marching.
