another way it seems to be is that a swimmer training in zone two or hit is using very different muscles from a runner or biker so those swimming mussels ar training their mitochondria to built more numbers of mitochondria and more efficient mitochondria . But when you get on a bike those legs muscles are not trained and so they fail far sooner and done reflect teh capability of the body as a whole so is it valid to do a vo2 max on a bike or treadmill for a swimmer?
What are the best strategies for actually building muscle in postmenopausal women? I personally do quite a bit of strength training with Farmers walks, squats and trap bar deadlifts yet my muscle mass seems to stay pretty static. Strength training has improved my bone density via dexa scan but my muscle mass does not seem to increase. My older female patients are also asking about this. Thanks! Great book and great podcast btw
