I dislike most forms of exercise but recently started volunteering to walk homeless dogs at the local Animal Shelter. And I love it!
The dogs are sooo grateful to be out of their cages and I am so happy seeing them so happy that I barely notice I am exercising! Lots of fresh air, feel so healthy and happy, and I HAVE LOST NEARLY A STONE !
Give it a go. The Shelters(and dogs) are desperate for walkers. It's a win win!
