Well you can all rejoice as science has done it again and shown that having sex is a legitimate sex burning workout. High fives all round.
According to research carried out by Antony D. Karelis, a professor of exercise science at the University of Quebec, the average man burns four calories a minute and a woman burns three while they are getting jiggy.
So if you have a sex session that lasts 25 minutes, you can kiss goodbye to about 75 calories - that's just shy of half a Kit Kat (107 calories).
But if you want to really boost it and enjoy the entire Kit Kat (dream big) try these sex positions that will give you a real workout.
3 sex positions that are as good as a workout
1. The baby monkey
Plant your feet on the ground and push yourself up on your hands, so you are in a bridge position. He goes on his knees and enters you from on top, supporting his weight on fully outstretched arms. Wrap your arms around his back and support your weight on your legs and with a strong core. Will tone your abs and thighs (and his guns).
2. The see-saw
He lays with his shoulders on a chair and feet firmly planting on the floor to create a plank. You straddle him, pulling your feet up behind you on his thighs and using his hands for support. Your abs are now in control. Use your core strength and thigh muscles to get you one step closer to that post-sex chocolate bar.
3. The sexy plank
Do a plank like you do in circuit training, but separate your hands and put them palm down on the floor to support you - almost in a low push up. Orgasms and a flat stomach are yours for the taking.
