In episode 21 of the RBI Performance Podcast, Steven and Blair continue exploring the Summer Strength Series by taking a closer look at core training. What exactly is the core? Why has it been so cool and trendy for so long? Is it possible to do a core exercise without a bouncy physioball or half-ball device? Short answer - YES! Within this episode, you'll hear what exercises the guys prefer, when they prefer to do them, and you'll also see them both get on their soapboxes and give some hot takes. Enjoy!
