Q&A: Insulin resistance and hypertrophy, stimulant metabolism, and BMR variability
The Stronger By Science Podcast
Podcast episode wrap-up and sponsor mentions
The speakers express their gratitude, announce changes to the podcast lineup, talk about receiving spam messages and offer a giveaway for the first three people who understand a deep-cut reference. Mention of sponsor ads from McDonald's and Angie (formerly Angie's List) is made.
In this Q&A episode of the podcast, Greg and Lyndsey answer questions about how to research a new subject, the effect of diabetes or insulin resistance on hypertrophy, how a pump might affect moment arms in movements, how much is too much isolation work, and more. They also give an update on the future of the podcast and announce that Dr Pak and Dr Milo Wolf are teaming up with Stronger By Science.
