If you want to work your abs, try cowgirl: In this position, you can flex and tense your abs while ‘riding’ your partner. The action of swivelling your hips utilises your core and pelvic muscles.

If you want to work your core, try missionary: The thrusting action strengthens your abs. Amp up your workout by focusing on pelvic lifting (so, not just using your lower back). The key is, if your partner is on top, you should thrust back with equal force to really get calories burning.

If you want to work your butt, try arch: Like bridge, except your shoulders stay on the ground (well, bed) hold your glutes as high as possible and squeeze and contract them with each thrust. Since the rest of your body is relaxed, the workout is focused entirely on your lower half which means its extra effective.

If you want to work your butt, try standing suspension: Wrap your legs and arms around your partner with your back against the wall. The action of squeezing your glutes to stay holding onto him is an awesome workout.

If you want to work your abs, try doggy-style: When you’re on all fours, you use your core to stabilise yourself and brace for impact (which sounds like just about the unsexiest thing ever). This position activates your stomach muscles, toning and strengthening – plus it’ll work your arms too!

If you want to work your arms, try wheelbarrow: The weight of your body is supported by your arms when you’re facing downward in the wheelbarrow position. It also works your shoulders, like suspension training at the gym. Just more fun.
If you want to work your legs, try squat: Balancing on your partner's lap, lift your butt up and down - your quads and calves quickly begin burning fat due to the strenuous nature of the position. Have your partner hold under your bum for extra support - and don’t expect to be able to hold this position for long, unless you’re a certified gym junkie!
