Prof. Keith Baar: The goal is to fail: the secret of resistance exercise & rhythmic exercise for health

 Professor Keith Baar

 increasing muscle protein - to increase volume of heart

muscle weakness causes illness...

 "For those who worry about mTOR activation and longevity, they are correct. Many animal studies show that drugs and diets that decrease mTORC1 activity throughout the body increase longevity. That is also what exercise does. When I increase mTORC1 activity in muscle by doing resistance exercise, the activity of the kinase goes down in the liver, other tissues of the viscera, and in immune cells. So, even when we increase mTORC1 activity in muscle, activity decreases in most of the other tissues of the body"

 Muscle is the most costly tissue and so heavy resistance exercise needs animal protein and dairy so that mTOR senses the ability to grow bigger muscles...

Alcohol blocks mTOR sensing the increase in protein to grow more muscle.

 "As to the strength comment, the listener is correct that to maximally increase strength it is important to lift a heavy weight. However, I disagree about the part where they say “accelerate the weight as fast as possible”. That is power (force x velocity). Power has nothing to do with the development of strength. Doing one heavy top set and stopping when bar speed begins to slow down is how we would train athletes to maximize strength. However, you and I were talking about longevity. Since his approach would increase risk of injury (because it would introduce a lot of jerk), it is not how we would train for longevity."
