In this video you state that golfers should be "using core muscles" of their body to move the mop. Back in my university days (35 years ago), voluntary muscles were classified as either "postural" or "phasic". Postural muscles were also termed "anti-gravity muscles" in that they kept us upright or in specific postures while our phasic or "moving" muscles produced desired motions to do work. I believe that "core" muscles in current jargon refer to the old "postural" muscles. Maybe I'm wrong. However, if core muscles do refer to muscles that ideally are used for stability and balance, then we shouldn't favor them to play golf well. Humans should use their arms and/or legs to best move objects or themselves around in space. I think confusion arises when the mucles that move our pelvic and thoracic girdles are considered core muscles. I don't think they are. These girdles are part of the skeleton's appendicular system which can be defined as our limbs. From walking or sprinting to pitching, kicking, or punting, or from jumping or lifting to bowling, boxing,or golfing, the phasic muscles of our arms and legs do a much better job than postural muscles in creating the speed, strength, and accuracy to be really good at most sports. I hear Chamblee, Kostis, Doyle, and now you, et al, telling golfers to use their core muscles to hit the ball better.

Are core muscles our postural, antigravity muscles or are they our phasic muscles? If there were an age old question as to whether the torso should move the arms and legs around or whether the arms and legs should move the torso around, the arms and legs moving the torso would trump the day, every day, all day. But what do you call these arm and leg muscles?
