Adherence
High-intensity resistance exercise training is the most effective intervention for improving muscle strength and mass in older adults with sarcopenia.
Start resistance training 2-3 times per week. You do not need to do it every day; even once a week helps. Focus on high intensity (challenging weights) to get the best strength gains. It is safe even for very old people and those with other health issues, but you need the motivation to stick with it.
GoodSupportsHIGH confidence
Resistance training remains the most effective intervention for sarcopenia... Improvements in muscle strength can be achieved with as little as one resistance exercise training session per week... doing PRT 2–3 times per week improved physical function... and more importantly had a significant effect on muscle strength especially in the high intensity training groups.
Why this rating
Supported by multiple RCTs and a Cochrane review of 121 trials, though some individual studies show modest results.
