Bryan Johnson explains why sled training is ideal for older adults. A sled can hold a thousand pounds without moving, making it nearly impossible to injure yourself while still building muscle and joint strength. He uses his own parents in their 60s as an example of who can benefit.
Good job. How hard can you work? How hard can you work? Awesome. So my parents are in their 60s, but it was them who made me realize this is actually for everybody. I'm going to show something. Take the belt off. We're going to look at how this relates really specifically to aging, which is that there could be a thousand pounds on this sled. It just wouldn't budge. So there's a fundamental difference between weight bearing down on you, which is totally fine weight training, but this is an underlying fundamental to weight training. There could be a thousand pounds. It just wouldn't move. See, it's almost impossible to hurt yourself on a sled and allows you to get all those rehab benefits. I don't know any of anything that actually compares to the sled. If you go into a gym, you see $5,000 treadmills lining the place. So this is actually a much cheaper method of exercise.
