Balance exercise prevents fallsStrong evidence
In a Cochrane review of 108 trials with 23,407 people, average age 76, exercise cut the rate of falls by 23% and the number of people who fell by 15%, with high certainty. Programmes built on balance and functional exercises cut falls by 24%, and those that added strength training probably cut them by 34%.
The World Falls Guidelines recommend balance-challenging, functional exercise 3 or more times a week, tailored to you, made harder over at least 12 weeks and then kept up.

More challenge and more time, bigger effectsEmerging evidence
Programmes that challenged balance and added up to more than 3 hours a week cut falls more: by 39% when both were true. This comes from comparing trials with each other, so it is less certain than the main result.

The Otago home programmeStrong evidence
Otago is a set of leg-strengthening and balance exercises done at home three times a week, with walking, prescribed by trained staff. Across four trials of 1,016 people aged 65 to 97, it cut falls and fall injuries by 35%, and people over 80 gained most in fewer injuries.
Keeping going is the hard part: in a review, only 36.7% of people were still exercising three times a week at 12 months.

Balance and strength built into the dayEmerging evidence
In one trial of 317 people aged 70 and over who had fallen more than once, building balance and strength moves into daily routines, an approach called LiFE, cut falls by 31%.

Strength training keeps you independentStrong evidence
In a Cochrane review of strength training in older adults, strength improved a great deal (73 trials), and so did getting out of a chair. Gains in walking speed and everyday tasks were smaller.
Sarcopenia, the loss of muscle strength and mass with age, is now defined first by low strength, and strength training is its first treatment.

Very old and frail people still gainStrong evidence
Ten frail nursing-home residents aged about 90, up to 96, gained 174% in thigh strength in 8 weeks of heavy strength training, and walked faster. In 100 residents with an average age of 87, 10 weeks of strength training raised strength by 113%, against 3% in those who did not train.
Those trials were small, but a large one points the same way: in 1,635 inactive people aged 70 to 89, 30.1% of those in a walking, strength and flexibility programme lost the ability to walk 400 metres over 2.6 years, against 35.5% in a health education group.

Frailty is a reason to startStrong evidence
International guidelines strongly recommend a programme of mixed activity with strength training as the first treatment for frailty. The UK guidelines say that, for people living with frailty, any increase in light activity and any reduction in sitting is a start.

Strength and balance training is safe for most peopleStrong evidence
Across more than 38,000 trial participants, over 11,000 of them older adults, exercise did not raise the risk of serious adverse events, and serious problems were rare in 121 trials of strength training. In the falls trials, most problems were minor muscle and joint complaints. In the LIFE study, serious adverse events were about as common in the exercise group as in the health education group (49.4% and 45.7%).

Chair exercise: some strength, not balanceEmerging evidence
In a review of 14 small trials, seated exercise improved thinking skills and, a little, strength and mood, but not balance or mobility, and it did no better than exercise on your feet. Experts agree it should be used to work towards standing exercise where possible.

Tai chiEmerging evidence
Tai chi may cut the rate of falls by 19% (low certainty) and cut the number of people who fall by 20% (high certainty), and the World Falls Guidelines recommend it. It is a class rather than a single move, so it has no demo here.

Walking and stretching: good, but not falls preventionMixed evidence
In people aged 60 and over, more daily steps were linked to lower mortality up to about 6,000 to 8,000 steps a day; this comes from observational studies. But walking programmes have not been shown to prevent falls, and no falls trial has compared stretching with no exercise, so neither counts as falls prevention.
