Okay, by now you're months, and months, and months, maybe years, into building your perfect golf swing, depending on how much time you could put into it. We're finally ready to add the final part of the swing, and the final part is this trailing arm. The right arm is what's going to help passively, primarily, transfer energy from your rotating trunk into the golf club. Just by the sheer fact that the right hand is on the club, and you're turning your body, it's transferring energy to the club. You don't have to try and actively throw your hand.
Now, as you get very skilled at putting all of these pieces together, and your body is very lead, or very core driven, and weight-shift driven, and lead-arm driven, you can start to add some right arm extension and some rotation to help speed the club up. That's when everything is really clicking and you need to get an extra 20 yards out of a drive. You can start putting a little more right arm in there. That's where the throw-the-ball drill is. If you're really lead-side dominant, it's perfectly fine to start adding some right arm in there, but you have to do so with some control because, all of a sudden, when you start pushing from the right side, it's very powerful, but it also has to be used with exercising some caution here, because it can start, all of a sudden, leading you back into the old problems that you have.
By now, you've done so many reps with your lead side and your core, that shouldn't be a problem for you, right? If you've been doing the drills, adding the right arm is going to be a natural extension. You're going to feel like it's really not even there. Ideally, the right arm is going to feel very passive. It's still going to work way more than you realize, but I want you to feel that it's very passive. As you've gone through a lot of these drills, you've been able to let the right hand come off. That should still feel like the case because that's going to allow the club to accelerate independent of your body and allow it to move faster.
As you go through these drills, everything, again, is still core-centric, weight-shift driven. That's still where your mindset is, but the right arm, we're starting to train it to get into the right positions that it needs to and how it can help you add power in your golf swing.
