I’ve never been a big fan of “training aides” but I saw that tour striker was having a pretty good sale on their smart ball. This thing is a small inflatable ball with a lanyard attached and it helps you focus on staying connected. The thing I’m that it taught me was to feel the elbows squeezing together throughout your entire swing! This has been a game changer, I’m striking the ball pure so much more and I’ve actually gained distance too! If you are looking for a training aid to try I highly recommend this one!
