According to research from the University of Cambridge, you can not do too much exercise later in life.
The study of 15,000 Britons aged 40 to 79 found that active men and women who increase their fitness levels cut the risk of early death by half.
The study found that people who follow the government's instructions to exercise 150 minutes a week could reduce the risk of dying by almost a quarter compared to sofa potatoes.
This can be achieved by daily training for about 20 minutes or five times a week for 30 minutes.
However, the best results were achieved for those who were already active on average
42 minutes a day – who managed about 20 minutes more.
Such participants reduced the risk of early death by 42 percent, the study found.
Activities included office work and walking and leisure activities such as cycling or sports.
The study, published in The BMJ found that people experienced "significant" benefits – regardless of how much sport they had previously done.
The researchers studied 14,599 men and women aged 40 to 79 who were examined between 1993 and 1997 and followed until 1997 in 2016.
Higher levels of physical activity and an increase in physical activity over time were both associated with it associated with a longer lifespan, the study said.
Individuals who were inactive at the beginning of the study and gradually met the 150 minutes per hour guidelines One week (20 minutes per day) of moderate physical activity over the next five years had a 24 percent lower risk of dying than those that stayed inactive.
Those who trained from 300 minutes to 450 minutes a week saw the biggest increase – with a 42 percent drop in mortality rates.
This could be achieved by daily movement of 64 minutes instead of 42 minutes.
"These findings are encouraging, not least for middle-aged and older adults with existing cardiovascular disease and cancers, who can still achieve significant life-expectancy benefits by becoming more active and having the overall health benefits of physical Continue to support activity. " Researchers said.
"In addition to shifting the population towards compliance with minimum physical activity recommendations, public health efforts should also focus on maintaining physical activity levels, in particular to prevent decreases in middle to late life."
There were 3,148 deaths during the study period, including 950 deaths from cardiovascular disease and 1,091 deaths from cancer.
Huw Edwards of the nonprofit health association Ukactive said: "This study provides further evidence against the obsolete idea that people should do less if they get older or if they have long-term illness. It is time to reflect on how we are going to approach our later years. Daily physical activity is a crucial ingredient in maintaining our health, happiness, independence and social relationships. Only by re-imagining aging can our society reduce the growing burden on our NHS and social care systems.
Louise Ansari of the Center for Aging Better said, "These are significant results. People live longer and if we are more active in their forties and fifties, we will have a healthier life later.
"But many of us do not do the amount of physical activity we need, not just aerobic exercise like running or cycling, and all adults should do activities twice a week to strengthen their strength and balance
"A good mix of exercises can help everyone stay healthy, active, and independent."
