Even the idea of working out can send a feeling of dread straight to the pit of your stomach. Running mindlessly on treadmills, trying to keep your balance on the cross-trainer, squating – they’re all just torture methods in disguise.

It doesn’t have to be that way though. Here are three fun things you did as a kid that can give you a great cardio workout and tone those abs.

Hula Hooping:
It’s a cardio workout that strengthens your core, can prevent lower back pain, improves your coordination and burns calories. Basically, it’s amazing. A kid’s hoop will do, but do consider investing in a special exercise version that’s weighted for a more efficient workout.

Skipping:
Whether you use a skipping rope or your broken clothes line, skipping is one of the best cardio workouts around. Mix up your routine with a few different techniques, while keeping a decent pace and you could burn an average of 12 calories per minute. Just take care to wear good shoes and avoid very hard surfaces in order to protect your knees.

Trampolining:Bounce your way to a healthier body. By staying on the trampoline for at least 15 minutes at a time, you can give yourself a great workout. Add some star jumps and even a couple of tumbles if you’re brave (or coordinated!) enough and you’ll be in great shape.
