We advocate a 'core lift' while swimming freestyle.  Using our drag pressure meter, Coach Gary measured the difference between a relaxed core and a lifted core.  This core lift is often taught in Yoga where the lower lumbar is flattened to the floor while laying on your back.  Naturally the lower lumbar is lifted in this position and takes work in order to get comfortable with a flat back.  In this video we demonstrate core lift exercises that will allow you to understand and improve this critical movement.  Gary then analyzes Olympic Sprint Freestyler Brad Tandy using a velocity meter analysis.  Find out what the difference between a 'relaxed core' and a 'lifted core' is!
