So, we've talked about the sick aging phenotype and exercise medicine and the power

We want our exercise medicine to cover as many fitness attributes as possible.

Our exercise prescription must attack the sick aging phenotype.

It must be specific and effective.

And finally, we need our exercise prescription to be efficient

and as simple as possible. But no simpler. What fits the bill? Barbells. Hi, I'm Jonathan Sullivan and welcome back to Graysteel.
