Caregivers in Hong Kong most often see three scenes: an older person at the park “pulling the rope machine and the pulleys”, at the elderly centre “riding the stationary bike or pedal exerciser”, or at home “pulling a resistance band”. The question is: are these exercises really effective for an older person’s muscles, and can they be used to reverse sarcopenia? The answer is not a simple yes or no. These exercises are not necessarily a waste of effort, but it must first be clear whether the goal is “building muscle” or “preventing falls”. This article assesses each against the standard of progressive loading, and separates the two goals that are so often mixed together.
Improving sarcopenia needs progressive resistance
The one core ingredient for reversing sarcopenia is enough, progressively increasing mechanical load (mechanical overload). The parent section already sets out clear training targets: about 60 to 80% of the one-repetition maximum (1RM), 2 to 3 sessions a week, and progressive overload (adding load step by step) according to ability. The specific prescription and evidence are in the parent section on resistance training, the one core treatment with evidence. Measuring the exercises commonly done by older adults against this standard makes one thing clear: whether the resistance is heavy enough, and whether it can be increased step by step, decides whether an exercise can build muscle. Preventing falls is a different matter and is achieved through balance training.
Building muscle and preventing falls are two different goals. Building muscle needs progressive weight-bearing training, whereas preventing falls needs balance training. The same exercise can help with falls prevention and heart and lung fitness while doing little to build muscle, because different exercises target different bodily functions.
What park rope pulleys and pulley machines do
The rope pulleys and pulley machines commonly found in parks generally offer light resistance. They mainly work on range of movement (ROM) and are hard to make heavier as the person progresses. A mixed-methods pooled analysis of outdoor fitness parks (Ng 2021, 9 studies) found that for fitness measures such as the 30-second chair stand and single-leg stance, this equipment did not reach statistical significance, and there was no evidence that it raised overall physical activity.
What exercise bikes and pedal exercisers do
The benefit of the stationary bike (cycle ergometer) for older adults lies mainly in cardiorespiratory function and metabolism and not in building muscle. A literature review of adults over 70 (Bouaziz 2015, 25 studies) found that cycling training has positive effects on preventing cardiovascular disease and improving metabolism, with systolic blood pressure down by about 8 to 16%, and that it improves cardiorespiratory endurance. However, the muscle growth that cycling drives is slower than with resistance training, takes longer, and needs a high enough intensity. In other words, building muscle is not the strength of the exercise bike.
A controlled study covering 38 RCTs (1,682 people in all) (2024) compared the effects of the two kinds of exercise clearly. Aerobic exercise is better at raising maximal oxygen uptake and six-minute walk distance, whereas resistance training is better at increasing lean mass, which means increasing muscle. An exercise bike therefore cannot replace strength training, but it is a good addition for training the heart and lungs. Doing both together works best, but to increase muscle, an exercise bike alone is not enough.
What resistance bands do and the conditions that apply
Of the three, the resistance band is the only tool with the potential to be “upgraded” into real resistance training, provided it is used correctly. A pooled analysis (Meng 2025, 25 RCTs, 1,318 people) found that resistance band training improves older adults’ lower limb strength and balance, with a positive overall trend. The study also stressed that for strength to increase, the training period needs to be at least 8 weeks, with the best effect beyond 12 weeks, and a programme that increases resistance progressively. Another pooled analysis (Lopes 2019) found that the strength gains from resistance bands and from conventional gym equipment are in fact similar (the difference in effect was not statistically significant for either the upper or the lower limbs).
- Choose a resistance heavy enough (hard work but the movement can be completed)
- Increase step by step: when it can be done easily, change to a stronger band
- Continue for 8 weeks or more on a progressive programme, with strength similar to conventional equipment (Lopes 2019)
- The resistance is too light and never increased, so no adaptation is triggered
- Training stops after a few sessions, before reaching the 8-week threshold
- Treated as a loosening-up warm-up and not as a muscle-building prescription
Whether pulling a band works depends not on whether a band is used but on whether the resistance is heavy enough and whether it is increased as the person progresses. In the study by Meng 2025, the range of data for some test measures was wide and results differed between studies, so the finding should be read as “generally helpful”, and a single figure should not be taken as an absolute conclusion and exaggerated in promotion. How to use a band correctly, how to choose the resistance, how to add load step by step and how to perform the standard movements are best learned under the guidance of a physiotherapist.
Building muscle and preventing falls need different training
This is the idea in the whole article that most needs correcting. Many exercises for older adults seem effective because they really can reduce falls, but preventing falls depends on balance and not on muscle strength. A Cochrane pooled analysis (Sherrington 2019, 59 studies, 12,981 people) showed that exercise overall can reduce the rate of falls by 23%, with balance and functional training reducing it by about 24% and multi-component training that combines balance and resistance reducing it by about 34%. Tai chi is a representative form of balance training. A pooled analysis (Huang 2017, 18 trials, 3,824 people) showed that practising tai chi significantly lowers the risk of falling (RR 0.80) and the rate of falls (IRR 0.69).
Activities with lighter resistance (such as park fitness equipment, cycling and tai chi) do benefit heart and lung function, joint movement and balance, but they cannot provide the progressive resistance needed to improve sarcopenia. Tai chi and balance training are well worth doing, but their aim is to prevent falls and not to build muscle. For the specific help tai chi gives to older adults, see tai chi and falls prevention. For specific advice on falls prevention and balance training, see balance training to prevent falls in older adults.
Common approaches that do not build muscle
None of the following common approaches can be used alone to build muscle. Knowing this avoids wasted effort:
Practical advice for arranging exercise for older adults (clinical consensus)
The key points above can be put into a practical order of steps. What follows is practical consensus and not the conclusion of a single RCT. The actual training intensity and arrangement must be set through a home exercise therapy assessment, tailored to the individual abilities of the older person.
- 1Assess firstBefore starting, a physiotherapist measures the older person’s grip strength, walking speed and balance and reviews the past medical history, and then sets the starting exercise intensity and rehabilitation goals from the results.
- 2Build muscle with progressive resistanceUse gym equipment or a resistance band with enough resistance, train for 8 weeks or more, and add resistance slowly as the person progresses. If the resistance is too light, the muscle-building effect is not reached.
- 3Train balance separately for fallsArrange tai chi, balance practice and functional movements specifically to prevent falls, planned separately from muscle-building training.
- 4Use low-load activity as a supplementPark rope pulleys and an exercise bike at home can be used for warming up, training the heart and lungs and keeping up social activity, but should not be treated as the main training to build muscle.
- 5Frail older adults: graded supervision by a physiotherapistThe starting intensity, the speed of adding load and the movement posture all involve safety. Someone must be on hand during training, and the therapist sets a suitable level of difficulty according to the older person’s ability. This is the main role of home physiotherapy.
