Having sex on a daily basis can cut the risk of heart attack and strokes.
A study has found that brief bursts of intense activity each day - including getting it on in the bedroom or climbing the stairs - could be lifesaving.
Scientists argue that this good news for people - particularly females - who can't stand getting a sweat on.
NHS GP Dr. Hana Patel told The Sun newspaper: "As having sex increases our heart rate, sex counts as exercise - especially given it does not last long (usually!).
"But it would need to be with some gusto to count as vigorous exercise - the same running for the bus, bursts of power walking while doing errands or playing high-energy games with the kids.
"Short bursts of activity burn more calories, increase metabolic rate, and improve endurance and strength - all in less time.
"Simply ramping up your activity for a few minutes, a few times a day can improve health."
