The fact that exercise is important is not exactly news, but a recent study has show just how significant - and long-lasting - the effects can be.
The study's findings were such that researchers concluded resistance training should be prescribed for older people by their GPs.
The research was carried out by Dr John Travers and colleagues in Trinity College Dublin and was recently published in the British Journal of General Practice. The team analysed 46 studies, involving over 15,000 people, and focused on preventing fragility in older people.
The team found that 71 per cent of the studies reported an improvement in frailty following interventions - and a combination of strength training and a boost in protein was most effective. The results prompted the team to recommend 20 to 25 minutes of exercise four times a week, for older people, to strengthen arms and legs and improve balance and co-ordination. People are living longer so keeping the body fit and strong is essential, and it seems it's never too late to start.
Not quite in your sixties or seventies just yet? Good news: staying fit in your younger years could have a huge impact later in life. Earlier this year, a study from Ball State University in America, which was published in the Journal of Applied Physiology, yielded some dramatic results.
It found that the muscles of older men and women who have exercised for decades are identical in many ways to those of healthy 25-year-olds. They were essentially about 30 years younger biologically than their chronological ages.
Now if that’s not motivation to get a bit more fitness into your life right now, we don’t know what is!
