The Surprising Workout That's Aging You Faster

Dr. Gerald Imber, an American surgeon, has become an online sensation due to his wildly viral videos on social media.

In each video, Dr. Imber promises (and delivers) to unveil truths the world isn't ready to hear—truths that not every doctor would dare to share so openly.

"Half my patients appreciate my honesty, while the other half... well, they definitely hate me for it," Dr. Imber admits.

Imber, a practicing surgeon, argues that long-distance running damages your knees and speeds up the aging of your facial skin. "If you're sticking to short distances, you're fine. But running long distances every day is something I wouldn't recommend at all. It harms your knees, ankles, and back."

But how does he define long and short?

Dr. Imber clarifies he's not talking about a jaunt down a street or two that may take over 20 minutes. "Running for just a few minutes in each workout is okay. Beyond that, it's simply not healthy for your legs or your face. As we age, our bodies produce less collagen and elastin. So, I recommend achieving your fitness goals—whether it's weight loss or maintaining good health—through other exercises aside from long runs. Consider cardio, weightlifting, or even Pilates. Just don't opt for runs lasting more than 20 minutes daily."

As expected, the video blew up online, garnering millions of views, likes, and comments. Here are a few reactions:

"I'm a personal trainer," wrote a woman named Elizabeth Noël Donovan. "I completely agree with you."

"I've always heard walking is better than running, but swimming is the best of all."
