Christos is a practicing physical therapist who published a paper titled 'Running economy: A comprehensive review for passive force generation'. On The Run Smarter Podcast today, we break down the concept on running economy and how you can apply this into your running to become a more efficient runner. We remove the scientific jargon so any runner can understand and finish with some practical take-aways. Some topics we discuss are: What is running economy & why is it so important? Why is lower-limb stiffness a good thing? How can we test our leg stiffness & running economy? What can we implement to help running economy including strike pattern, footwear and strength training If you have any questions for Christos you can e-mail him here If you would like to support the podcast and participate in future Q&As sign up for $5US per month at https://www.patreon.com/therunsmarterpodcast Check out our new website!! https://www.runsmarter.online  To follow the podcast joint the facebook group Becoming a smarter runner click on the link:  https://www.facebook.com/groups/833137020455347/?ref=group_header To find Brodie on instagram head to: https://www.instagram.com/brodie.sharpe/
