At least 75% of people age > 65 years do not exercise at recommended levels despite the known health benefits of exercise:
Improved quality of life (eg, endurance, strength, mood, sleep, flexibility, insulin sensitivity, possibly cognitive function, bone density [with weight-bearing exercise])
Furthermore, many older people are not aware of how hard to exercise and also do not appreciate how much exercise they are capable of.
Exercise is one of the safest ways to improve health. Because of the decline in physical capability due to aging and age-related disorders, older people may benefit from exercise more than younger people. Exercise has proven benefits even when begun in later years. Basic, modest strength training helps older patients carry out activities of daily living. Many older patients need guidance regarding a safe and appropriate regular exercise regimen.
The largest health benefits occur, particularly with aerobic exercise, when sedentary patients begin exercising.
Strength decreases with age, and decreased strength can compromise function. For example, almost half of women > 65 and more than half of women > 75 cannot lift 4.5 kg. Strength training can increase muscle mass by 25 to 100% or more, meaningfully improving the ability to carry out daily activities. The same degree of muscle work demands less cardiovascular exertion; increasing leg muscle strength improves walking speed and stair climbing. Also, institutionalized older people with more muscle mass have better nitrogen balance, less deconditioning, and a better prognosis during critical illness.

Most patients with relative contraindications can exercise in some form, although typically at lower levels of intensity and in more structured circumstances than other patients (see Cardiovascular Rehabilitation Cardiovascular Rehabilitation Rehabilitation may benefit some patients who have coronary artery disease or heart failure or who have had a recent myocardial infarction or coronary artery bypass surgery, particularly those... read more ). At times, shorter bursts of higher intensity (and sometimes even low or moderate intensity) exercise with rests between attempts can be more accommodating than sustained moderate-intensity exercise. Intensity and duration can be modified over time as appropriate. The exercise program may be modified for patients with other disorders (eg, arthritic disorders, particularly those involving major weight-bearing joints, such as the knees, ankles, and hips).
Patients should be clearly told to stop exercising and seek medical attention if they develop chest pain, light-headedness, or palpitations.
Before beginning an exercise program, older people should undergo clinical evaluation aimed at detecting cardiac disorders and physical limitations to exercise. Routine ECG is not required unless history and physical examination indicate otherwise. Exercise stress testing is usually unnecessary for older people who plan to begin exercising slowly and increase intensity only gradually. For sedentary people who plan to begin intense exercise, stress testing should be considered if they have any of the following (1 General reference At least 75% of people age > 65 years do not exercise at recommended levels despite the known health benefits of exercise: Longer survival Improved quality of life (eg, endurance, strength... read more ):

Lung disease, known or suspected
For people recovering from an injury, the clinical evaluation before the start of an exercise program should assess whether they are apprehensive about the exercise program. The evaluation should also measure the range of motion and strength of an injured area, particularly as compared to the other side (eg, an injured knee versus the opposite, uninjured knee). Other considerations include the ability to climb stairs, walk with a proper gait, and complete basic activities of daily living (BADLs), such as eating, dressing, bathing, grooming, toileting, and transferring (ie, moving between surfaces such as the bed, chair, and bathtub or shower). Athletes recovering from an injury should be able to do simple sporting movements before trying aggressive and more complex sporting movements.

A comprehensive exercise program should include
Flexibility and balance training
Variation (regular change in exercise to avoid overadaptation to the same stimulus, but also to avoid minor injuries due to repetitive actions)
Often a single program can be designed to achieve all exercise goals. Strength training improves muscular mass, muscular endurance, and strength. If strength training is done through a full range of motion, many exercises improve flexibility, and the enhanced muscle strength improves joint stability and, consequently, balance. Moreover, if rests between sets are minimal, cardiovascular function also improves.
Duration of aerobic activity for older people is similar to that for younger adults, but exercise should be less intense. Usually during exercise, the person should be able to comfortably converse, and intensity should be ≤ 6/10 on a perceived scale of exertion. Older people who have no contraindications can gradually increase their target heart rate (HRmax) to the one calculated by use of age-based formulas Aerobic exercise .
Some deconditioned older people need to improve their functional abilities (eg, by strength training) before they will be capable of aerobic exercise.
Strength training is done according to the same principles and techniques as in adolescents and young adults. Lighter forces (loads/resistance) should be used initially (eg, using bands or weights as light as 1 kg or arising from a chair) and increased as tolerated. More aggressive training (the use of higher resistance initially) should be under the supervision of a qualified fitness professional.
To help increase flexibility, major muscle groups can be stretched daily, although stretching ≥ 3 times/week yields some improvements. Ideally, major muscle groups should be stretched after exercise when muscles are most compliant.
Balance training traditionally involves challenging the center of gravity by undertaking exercises in unstable environments, such as standing on one leg or using balance or wobble boards. Balance training can help some people with impaired proprioception and is often used in an attempt to prevent falls in older people. However, it is often ineffective because any balance activity is skill specific (eg, good balance while standing on a balance board does not improve balance in dissimilar activities). For most older people, flexibility and strength training exercises prevent falls more effectively; they also mitigate the impact of falls Falls in Older People A fall is defined as a person coming to rest on the ground or another lower level; sometimes a body part strikes against an object that breaks the fall. Typically, events caused by acute disorders... read more . Such a program develops strength around the joints and helps people hold body positions more effectively while standing and walking. In people who have difficulty standing and walking because of poor balance, more challenging balance tasks (eg, standing on a wobble board) are simply likely to facilitate injury and are contraindicated.
