1. Sexercise - More Fun than Sit-ups and Burns More Calories than Pilates!

    KarmaSheetra Kama Sutra Positions Bed SheetThe NHS Direct website is promoting sex as a form of exercise, especially for those with limited time for a fitness regime!

    The health benefits of sex are numerous - it gets the heart and lungs working hard, uses every muscle group and burns around 300 calories an hour. Compared to Pilates, which on average only burns 210 calories an hour, you're really doing your body a favour!

    Not only that, orgasms can trigger the release of chemicals called endorphins which instantly calm us and banish stress. With a more relaxed mind and a tired body, you are sure to get a great night's sleep!

    And that's not all! The website explains:
    "Sex can actually help you live longer. The endorphins released during orgasm stimulate immune system cells, which helps combat illnesses.

    Orgasms also boost your circulation, helping the body rid itself of harmful toxins. Regular sex can even keep your heart healthy and lower your risk of heart attack.

    So, you can have a healthier heart, healthier body and calmer mind - all thanks to the healing powers of sex. And you can have lots of fun in the process too!"

    In order to make the most of your sexual workout, Lovehoney suggests investing in some KarmaSheetra Bed Sheets. Simply, place your duvet inside the covers and climb on top! Using the blue and pink symbols, place hands, feet, knees and bottoms in the correctly numbered positions and have fun working up a sweat!
