Adherence
Resistance exercise is the only intervention capable of consistently restoring muscle function and strength in sarcopenia, partially overcoming age-related anabolic resistance.
You must lift weights to regain strength and function. Aim for 2-3 sessions per week at a moderate-to-vigorous intensity (70-85% of your max). This mechanical load is the key signal your body needs to rebuild muscle function, which nutrition alone cannot provide.

Exercise remains the cornerstone of sarcopenia management, serving as the only intervention capable of consistently restoring function.

More from this paper
- Nutritional interventions (protein, leucine, HMB, creatine) preserve or modestly increase lean mass in sarcopenia but fail to consistently restore muscle strength or physical function when applied in isolation.Good
- Sarcopenia is driven by anabolic resistance, mitochondrial dysfunction, and chronic inflammation, which decouple muscle mass from muscle function.Good
