Strength training is key to staying healthy as people age, with experts recommending working major muscle groups at least two days per week.
Marfred Suazo, a fitness professional known as Fonz the Trainer in New York City, has worked with thousands of older adults to build strength and longevity.
Suazo spoke with Fox News Digital about which muscles are most important for seniors to target.
"Most people train what they see in the mirror — chest, arms, quads and maybe abs if they’re feeling ambitious," Suazo told Fox News Digital. "That’s what I call ‘mirror training.’"
The problem with focusing only on "mirror training," he said, is that you’ll end up out of balance, with rounded shoulders, a tight chest and eventually a sore back or knees.
"If you want to age strong, pain-free and confident, you need to flip the script," Suazo said. "You need non-mirror training — training the muscles you can’t see but feel every single day. These are the muscles that keep you standing tall, moving with power and living without pain."
Suazo learned firsthand about the benefits of this training when he was swimming competitively and training in martial arts.
