Many of us spend hours in salons and spas and hundreds of dollars at the cosmetic counter trying to look and feel younger. But the real answer may be in the gym.
One exercise, specifically weight lifting, has not only been shown to help you feel younger, but also live longer.
Duke and Jean Grossman have been lifting weights together for almost 15 years.
"I think it helps you in the long run," Jean said.
The couple started exercising after Duke had a stent placed in his heart.
"We're no different than anybody else. You want to keep on going, don't you," Duke said.
A recent study showed seniors who lift weights twice a week gain muscle mass while improving strength and power. It also helps with balance.
"Physiologically, it is the fountain of youth. It plays into brain, muscle and neurological. It is the fountain of youth," Sanford Senior Exercise Specialist Steve Bliss said.
Bliss says it's important to exercise safely, so you don't get hurt.
"I always start someone with two sets of ten. The American College of Sports Medicine recommends that. Then you won't get as much soreness," Bliss said.
After two to three weeks, Bliss recommends working up to three sets of ten repetitions with free weights.
"Do it slow and controlled and breathe. You will see a lot of people hold their breath. As you exert, you breathe out. As you come back, inhale," Bliss said.
Another thing to keep in mind is that free weights actually give you a better workout than machines.
"If you can do dumb bells and free weights, you'll get more production out of it," Bliss said.
Bliss also points out that more isn't necessarily better with weight lifting. You should not lift weights every day.
"What I do with adults is I recommend going twice a week for about 30 minutes," Bliss said.
That way your muscles have time to grow, repair and strengthen, something that's more important as you get older.
Duke and Jean have plenty of reasons to stay strong, active and healthy.
"We have two sons, four grandsons, two great-grandsons and two great-granddaughters," Duke said.
Another benefit of weight lifting is it’s been shown to reduce your risk of falling as you get older.
