There are plenty of ways to improve your cardiovascular health, including jogging, swimming, and cycling, and the benefits extend beyond a healthy heart. Aerobic exercise can help you avoid cramps, improves blood flow, and can even lead to better orgasms. "Strive for a workout intensity that pushes your heart rate to 65 to 85 percent of its maximum capacity," Hays says. "And don't forget the cooldown phase." Try adding 30 to 60 minutes of cardio exercise three to five times a week, and you'll quickly notice a boost in stamina.
