Death: It’s hard to talk about, and sadly, even harder to avoid. That’s why everyone wants to know how long they will live and there are many indicators that can show whether someone is thriving or on the decline. But scientists have yet to develop a magic formula to determine exactly how long someone should expect to live. Which, let’s be real, is probably a good thing. Knowing exactly how much time you have left to enjoy your life could cause a lot of anxiety, to say the very least. NBC News medical contributor Dr. Natalie Azar appeared on the TODAY show on March 8, 2023, to demonstrate a surprisingly simple test that may predict how long someone aged 51 to 80 has to live. The test is called the sit to stand test, also known as the sit-rising test or SRT, and it takes less than a minute to perform. How to take the sit to stand test The test is pretty simple. Go from standing to sitting cross-legged, and then go back to standing without using any parts of your body besides your legs and core to help you get up and down. The test measures multiple longevity factors, including heart health, balance, agility, core and leg strength and flexibility. You begin the test with a score of 10 and subtract points on your way up and down for doing the following: Hand used for support: -1 point Knee used for support: -1 point Forearm used for support: -1 point One hand on knee or thigh: -1 point Side of leg used for support: -1 point Two studies, 13 years apart, came to the same conclusion A 2012 study published by the European Society of Cardiology found a correlation between the SRT score and how long people live. A follow-up study published in 2025 in the European Journal of Preventive Cardiology further confirmed the SRT as a strong predictor of both natural and cardiovascular causes of death, reinforcing the original findings. The study was conducted on 2002 people, 68% of whom were men, who performed the SRT test and were followed by researchers in the coming years. The study found that “Musculoskeletal fitness, as assessed by SRT, was a significant predictor of mortality in 51–80-year-old subjects.” Those who scored in the lowest range, 0 to 3, had up to a 6 times greater chance of dying than those in the highest scores (8 to 10). About 40% of those in the 0 to 3 range died within 11 years of the study. What does your score actually mean? Azar distilled the study on TODAY saying: “The study found that the lower the score, you were seven times more likely to die in the next six years.” “Eight points or higher is what you want,” Azar said. “As we get older, we spend time talking cardiovascular health and aerobic fitness, but balance, flexibility and agility are also really important,” she stressed. A score of eight or nine means you’re allowed to roll forward onto your knees and then rise, which a lot of people will find more comfortable. If you can rise that way, you’re still in a pretty good spot health wise. One should note that the people who scored lowest on the test were the oldest, giving them a naturally elevated risk of death. Dr. Greg Hartley, Board Certified Geriatric Clinical Specialist and associate professor at the University of Miami, told the Atlanta Journal-Constitution that we should take the study with a grain of salt. “Frailty, strength, muscle mass, physical performance: those things are all correlated to mortality, but I would caution everybody that correlation doesn’t mean causation,” he said. And of course, the test doesn’t take into account injuries or disabilities that may make doing the test impossible. But one of the study’s authors says that the study is a call to take our mobility seriously. “The more active we are the better we can accommodate stressors, the more likely we are to handle something bad that happens down the road,” Dr. Claudio Gil Araujo, told USA Today. Even low-impact exercise like yoga can increase your mobility and flexibility and, thus, your SRT score.

It’s never too late to improve your overall health, fitness, and strength, so regular exercise is a great thing to incorporate if you’re not already doing it. A couple of specific skills that will help are boosting your ankle flexibility, hip mobility, and core strength. Trainers recommend incorporating squats, lunges, and planks into your regular routine. Just using your own bodyweight is plenty to get started, though if you’re up for incorporating any added loads, the strength training will do wonders for your bone density, as well. But remember that the SRT is just a measure of strength and mobility, which could correlate to an older person’s likelihood of suffering from a fatal fall. It doesn’t do anything to measure your cardiovascular health (vitally important especially in older people), for example. And it may not even be the most reliable longevity test out there. It has been criticized for its extremely unnatural range of motion. For starters, rising by pushing up on the sides of our ankles with our knees pointed outward is certainly not representative of a real-life situation. Some doctors insist that your comfortable walking speed is a better indicator of health and longevity, while others say grip strength is the key measurement. Remember, it is never too late to start healthy routines for a better quality of life. This article originally appeared three years ago. It has been updated.
