I certainly believe it.
I’ve actually come down 15lbs since March.
(I was already in decent shape)
I’ve been doing a lot of hill sprints and walking miles everyday.
I haven’t been eating out, and I got tired of being alone in my apartment all the time.
I get weeks off in winter so I know how dagerous time around the house is to the waistline. I started out being carefully and have dropped 5 but have been working half or three quarters of the time.
