It's almost unfair: Just when we should be enjoying the rewards of a lifetime of hard work, in our 50s and 60s, our bodies start to slow down. Muscles and joints ache, it's harder to lose weight, and fatigue is a constant problem.
This makes it difficult to play with kids and grandkids, do activities with friends, or even just move heavy objects around the house.
But according to the world's most famous trainer, this doesn't have to be the case.
"I feel younger at 61 than I did at 30," said Tony Horton, who trains many of the top celebrities in the world. "It's a method anyone can do that takes about one or two minutes a day. And within a very short period of time, you're going to feel stronger, and probably healthier, than you have in years."
The reason we experience these age-related problems is no mystery: Doctors now say all people lose muscle starting at age 40-50. Joint and bone problems soon follow, as well as packing on extra pounds that become harder and harder to lose.
While that may sound minor, it can add up over years and decades. Weaker bones and muscles contribute to bad falls, hospital stays, and serious long term health problems.
For years, Tony Horton believed the only way to fight these problems was with more exercise... and he is famous for training major stars like Bruce Springsteen, Tom Petty and Stevie Nicks, to name a few of his celebrity clients.
But recently, he's found a better way to combat these common health issues that has nothing to do with exercise. Actually, it starts with one thing: Food.
"We gave these superfoods to older athletes... people in their 50s, 60s, 70s and beyond. They all had the most incredible results of their lives," Horton said.
"Not only were they stronger, they had more energy, they even had better heart health," Horton said. "We thought... why are only athletes doing this? Anyone over 40 would want these results."
"And sure enough, when we gave it to non-athletes, the changes were even better."
Incredibly, studies have proven the results all seem to be traced back to adding 3 "superfoods" to your diet. The technique is simple, you do it from home, and it's now shown to work for people of any age, even people who don't exercise at all.
The changes in users have been so remarkable, Horton is now the subject of a short documentary detailing exactly how his body-strengthening method works. It's online and free for the public to view and share.

The video has since gone viral, first being shared by users on Facebook, then being featured on news sites like ABC and CBS.
So far, the comments and feedback have been outstanding, with thousands of Americans claiming they feel stronger than they have in years.
"I never would have believed I could feel like I did 10 or 20 years ago if I didn't actually try Tony's method," one viewer wrote.
"I'm hiking with my kids for the first time in years, this has literally changed my life," raved another. "This really WORKS!!"
Horton does make a simple request of those people who watch the documentary: "If watching this helps you build more muscle, get your body back and feel stronger, and even get more energy and confidence," Horton says, "Then please share this video with your friends and loved ones. Together, we can help so many people avoid these health issues."
