One of the things I found with HT was that as well as tending to do less exercise due to premature fatigue, what exercise I did was less vigorus than before I started HT and my waist size inevitably increased. This has continued to be a problem over the years, despite my only eating about half of the amount of food I used to consume. However, I used to play a lot of short tennis and table tennis and golf to a reasonable standard but am not now up to it, (back and legs), so it's now just slow walks. I really ought to do some gym work I guess!
