Aerobic exercise can't make your penis bigger. A number of studies and reviews have concluded that aerobic exercise can help improve ED by boosting blood flow. When working out, your heart is pumping faster. This "clears out" your veins from buildup and blockages caused by obesity, diabetes, high cholesterol, and heart disease (which all contribute to ED).
Aerobic exercise of moderate intensity for 5 to 7 sessions per week for 12 weeks increased nitric oxide levels by 32%. Remember that nitric oxide is what pushes blood flow into the penis for an erection and relaxes the penile muscles to allow for stiffness.
A 1990 study reported that aerobic exercise overall
— Increases levels of sexual intimacy
— Improves sexual function
— Creates more satisfying orgasms
— Boosts energy levels
— Lowers blood pressure
— Improves muscle tone
— Reduces body fat
— Improves self-image
— Better sleep
What kind of aerobic exercise should you be doing? Anything that gets your heart rate up! This could be running, using the elliptical, rowing, swimming, or dancing. Even good, old-fashioned walking has significant health benefits. Walking for 30 minutes every day reduced the risk of erectile dysfunction by 41%.
Whatever aerobic exercise you choose, get sweaty and get your heart rate up!
