According to the ACE (American Council on Exercise), a normal heart rate during sexual intercourse can average between 90 to 145 beats per minute, or around the same cardiac output as a 6.5 mph pace on the treadmill, and an hour of strenuous sex can equal roughly the same caloric expenditure as running 5 miles.
Unfortunately, for all those of you who despise cardio in any form (myself included), there is no way to escape this inevitable conclusion: you must workout your heart. And though hours spent on the treadmill, elliptical machine, or stepper quickly spring to mind, this doesn’t have to be the case. Alternatives such as boxing, jumping rope, and even weight-training exercises, between the range of 15 to 20 reps, are all excellent ways to increase your cardiovascular fitness.
The focus here is endurance, so try to increase the intensity and length of your workout each week by at least 5-10% for sustained progress—and watch your stamina skyrocket in the bedroom.
