Nobody is going to blame you if you can't face the thought of going to a gym at the end of a long day, or even at the start of one. You're tired, you have things to do, so you don't necessarily want to make the time to run on a treadmill or lift something heavy, put it down, and then lift it up again (repeat until your arms feel like they're going to fall off). Exercise doesn't have to be so regimented. If you want to become fitter and lose a bit of weight but hate the conventional approach, there are many ways in which you can incorporate physical activity into your life… while still having fun.
Get a Bike
How often do you use your car to make a fairly short trip? Maybe it's to visit nearby friends or family, or simply to pop down to the shops. Get a bike and use it when you might ordinarily use your car on a short trip. Nobody is expecting you to start training for the Tour de France, but these are trips that you would have made anyway. You will save money on petrol, get where you need to go, and become fitter without overdoing it.
Take a walk from time to time. It's really that simple. Whether it's taking a stroll around your neighbourhood, using the stairs instead of the elevator, or simply parking your car at the very edge of the carpark and walking the rest of the way. It's really not that complicated to add some more walking to your day. If you've ever wanted one (and are in a position to look after one), then get a dog. You'll have a delightful walking companion who really needs to be taken out each day.
Dance, Dance, Dance!
This is a dedicated cardio workout, and yet it's still tremendous fun. Join a local dance class, have fun, and work up a sweat. It doesn't even have to be all that intensive if you don't want it to be. Tap classes are something that can be enjoyed by anyone of any age or level of physical fitness. The same can be said about tango. If you really want an intensive workout while having fun, consider signing up for swing classes.
Play Like a Kid
OK, so maybe you might not want to hit the actual playground (but then again, go for it if you want to). But kids run around and play, often without a clear goal of exercising—and yet this is precisely what they're doing. What about an adult version of this basic concept? Get your friends together and have regular paintball or laser tag matches. You are doing little more than messing around and having fun, and yet you are still experiencing some highly-beneficial physical activity.
Exercise doesn't have to be boring. In fact, it doesn't always have to feel like you're exercising at all.
