What are the stupidest ways you can work out and still burn calories? Find out below with our suggestions for the top ten most ridiculous exercises.
- Stool parkour<p> If you're more at home sitting down then racing around, perhaps stool parkour might be up your street. Known as Sporthocker, this new trend from Germany involves bouncing off concrete while sitting on a stool. The most important part of the sport seems to be the ability to look nonchalant while sitting on your rear end in the middle of the street.</p>

- Nude workouts<p> The sheer horror of having to work out without any clothes on - imagine how much worse that gym trip would be if that sweaty man on the treadmill was in the buff - could put you off fitness for life. However intrepid Dutch gym goers started the first session of Nudifit in 2007, where they hit the exercise machines without clothes. Hope they wiped them down the exercise bike afterwards.</p>

- Space hoppers<p> Reclaim your inner child and bounce about on a space hopper for the silliest workout around. You can burn over 100 calories in 10 minutes with some serious hopping - think hill climbing on a space hopper and you've got the right idea.</p>

- Anti-gravity yoga<p> If you're bored of Bikram and had enough of Hatha, maybe anti-gravity yoga could get your prana flowing again. This type of yoga is practised with the use of a hammock suspended from a ceiling, enabling flexible yoga bunnies to defy gravity and achieve advanced postures.</p>

- Stiletto workout<p> Not a trainer fan? If you'd rather look sexy in your highest heels, try the stiletto workout. Originating in Crunch gyms in the U.S., the 45-minute workout involves lunges, squats and jumps, all performed in high heels. One word: ouch.</p>

- Laughter yoga<p> When you're down in the dumps, the last thing you want is to be surrounded by a lot of po-faced, grunting gym-goers. Try a session of laughter yoga (Hasyayoga), where the aim is to combine 'unconditional laughter with yogic breathing (Pranayama)'.</p>

- Cycle karaoke<p> If you feel like you're on the road to nowhere spinning away on the exercise bike at the gym, how about giving cycle karaoke a go? If you're belting out 'Girls Just Want To Have Fun' at the top of your lungs, you may just forget that you're burning serious calories too.</p>

- Drum workout<p> When the charms of your Mp3 player have worn a bit thin, cast off your headphones, grab a drum and start dancing. Group drum workouts get you moving constantly for an hour, enabling an impressive calorie burn of 600 calories or more.</p>

- Table tennis<p> Whether you know it as table tennis or ping pong, this childhood favourite may look a bit silly but is actually an Olympic sport. You can burn off a Starbucks Grande Latte (272 calories) with an hour of bat and ball action at the ping pong table.</p>

- Circus workout<p> The wonderful thing about the circus workout is that if you're scared of clowns, you'll probably burn even more calories through the sheer, terrified adrenaline rush. You can try tumbling, trapeze, balancing, juggling and, for the brave, unicycling to get that acrobatic physique. Clown mask optional, of course.</p>
