Exercise
How much exercise do you need? The WHO guidelines
150 to 300 minutes a week and strength training twice. The World Health Organization's guidelines for adults and older adults, made simple.
Older age
Many people think weakness and tiredness are just part of getting older. Frailty can get better, though, and it is never too late to start.

World Physiotherapy describes frailty as a long-term condition that can get better or worse, not an inevitable part of ageing. Signs include exhaustion, weakness, slow movement, balance problems and losing weight without trying.
About 12% of people over 50 worldwide are diagnosed with frailty and about 46% are pre-frail. The WHO lists frailty and falls among the main health problems of older age.
Over the years we lose muscle mass and strength. This is called sarcopenia and it affects balance and independence. World Physiotherapy stresses that older adults respond to strength training much like younger people: stronger muscles mean better balance and fewer falls.
More active people are up to 41% less likely to develop frailty.
In its ICOPE programme for the care of older people, the WHO recommends mixed exercise, with progressive strength training plus balance, flexibility and aerobic work, for people whose physical ability is declining and for people at risk of falls.
A physiotherapist checks your strength, balance and walking and builds a programme that slowly increases resistance and intensity. It can start simply, with standing up from a chair and resistance bands, and move on to weights.
If you have a heart condition or another long-term illness, talk to your doctor first. Most people can exercise safely with the right programme.
