Okay, this is wild: a top biochemist says you can literally turn your heart 20 years younger with a workout that takes less than an hour—and you only need to do it once or twice a week. It’s called the Norwegian 4x4 protocol: four rounds of 4-minute high-intensity intervals (think: bike, rower, treadmill) with 3-minute breaks. The science is legit, and people saw huge heart improvements in just two years. Who knew anti-aging could be this efficient? #Health #BodyHealth #AntiAging
