High-intensity progressive resistance training is the optimal prescription for treating sarcopenia and improving aerobic capacity in older adults, often outperforming moderate-intensity aerobic training in specific metrics.
If you have muscle loss (sarcopenia), you need to lift heavy weights progressively to rebuild strength and even improve your heart health as much as moderate cardio does. Don't be afraid of resistance training; it is essential for fighting muscle loss and can be just as good for your cardiovascular system as moderate walking if done with high intensity.
Sarcopenia (the loss of muscle mass, strength, and function with ageing) requires high-intensity resistance training for optimal adaptation... there is evidence that high-intensity progressive resistance training in older adults also improves aerobic capacity to a similar extent as moderate-intensity aerobic training
