Us adults need to do more fun stuff from childhood to get in shape- I'm convinced that it's the childhood fun and games that keep you thin!
I've been hula hooping, jump roping, playing volleyball in the water, playing badminton with the kids, bike riding- all the kids fun and games are what makes you laugh, have fun, and meanwhile, you're working out! Be the end for Dodge ball- all that going up and down to get the ball and throwing it at the kids will give you a fun workout. Not to mention, once you catch one of them, dodging the ball will also give you a little workout! I'm still too heavy to play tag, but one of these days I will try it again.
More kids fun stuff during the winter that give you a decent workout- ice skating, cross country skiing, building snowforts, snowball fights, snow angels and sledding. I love to sled! That three seconds coasting down the hill makes it worth the climb uphill with the sled to go again! Cross country skiing is a blast! I use hockey skates to ice skate, because for some reason, I am very unstable on figure skates (even when I was thin years ago, I couldn't figure skate), but the hockey skates, I can move around and have some fun. I'm very slow at it, but let me tell you, I get a dar gone good workout just going around on our lake doing this, and my thighs feel it the next day!
Play some soccer with the kids, or just kick a soccer ball around in the yard. Play some street hockey (with a tennis ball, of course, heh heh). Toss a softball or baseball back and forth with one of the kids or a friend- change arms, to make sure you're working out both of them. Play a game of 21 or Around the World with a basketball.
Horseshoes, croquet, Red Light, Green Light. I'm sure we can come up with a few more things to do to burn those calories.
Having fun is key for me to lose weight, and what better way than to get back to childhood games.
