Many of us have tried high-intensity interval training (HIIT) at some point, even if it was just a boot-camp class our friend dragged us to. But a new study suggests that we may want to incorporate those workouts — which include short bursts of intense exercise, followed by stretches of more moderate activities — into our regular fitness routines, since they’ve been shown to reverse the aging process.
Published in the journal Cell Metabolism, scientists from the Mayo Clinic recruited an equal number of women and men to participate in the study, and split them up into two groups: young (18–30 years) and older (65–80 years). The researchers then divvied the participants up another time, into three groups partaking in different exercise routines for a 12-week period.
One group participated in HIIT, which involved three days of cycling (high-intensity bursts fused with slower-paced intervals) and two days of treadmill walking each week. Another group focused on resistance training that consisted of two days a week of lower- and upper-body exercises, and the last group did a combination of the two — cycling less strenuously than the first group and lifting fewer weights than the second, for a total of five days of exercise a week.
At the end of the 12-week period, participants in each of the groups had improved overall fitness. However, those participating in high-intensity interval training saw the most benefits. The younger HIIT participants had their mitochondrial capacity — which helps the body create energy — increase by 49 percent, while older volunteers saw a 69 percent increase. The overall HIIT group also saw their insulin sensitivity improve, which means they potentially lowered their diabetes risk, and they had an increase in ribosome activity (which helps build proteins that create muscle cells).

There is no reversing the aging process.
If I HIIT it, will I live forever?
Its proven it can be slowed
you may be able to last longer if you ever get to HIT anything
Interesting article. My genes say I’m likely to live for a while but I’m intrigued with having better quality of life.
Slowed??? The clock doesn’t stop.

Laz is 128 years old and still going strong.
Just thinking about cycling for three days straight makes me tired.
In dog years I think he is close to 900.......
All exercise and low cal whole food diet is good.
Next month I am getting a bicycle to ride to go swimming in the lake.
Get one of these. It can be used for high and low intensity.
I use mine an hour every day. It’s 20 years old and built like a tank.

Which we already knew. And really pretty much any exercise regimen does that. One might be slightly more effective than others, but when you get right down to it the aging process wants to rot those muscles, and the best way to fight that is to use them.
I’m gonna run her in reverse for about 40 years. I’ll pay attention this time cause I’ve always been amazed I survived my twenties.
I row on a Concept 2 everyday also. Best in the world.
Sure there is. I use to be 54 years old, but now after some high intensity workouts I’m almost 8. And by the way: Paul Ryan is a doody face.

I heard that some years back ...
Treadmill and weights for me, along with a low-carb diet, shoveling snow in winter and gardening in spring, summer and fall.
