First 60 sec sprint on the Concept 2 evil rower looked good.Second sprint looked fine.Power at the...
Quick one tonight because the AMA audio series dies at midnight, but you can still hop in https://miket.me/physflex <--full details And before it dies, I need to tell you about the metabolic basement.
