 We're looking at using calisthenics as a vehicle to improve shoulder robustness and develop the athletic profile. It's not the build and all, it's part of the amazing work you guys are already doing. It's just, can we supplement it in some way to give you some more tools? Effectively. And how that fits into your program is entirely up to you guys. You can use as much as little or not as tall as you want. Calisthenics means beauty and strength. Those two components working together are well performed. Muscle up should look beautifully strong if it's done well. And you guys will know like from a sports perspective, anything which looks effortless from a movement or physiologic perspective requires less effort. And that's what we want our guys to get to from a more athletic position of like, if movement looks effortless, then we know we're in a good place. We've got a good selection of movement options which we can utilise. If we can have better physical literacy, if we want to call it that at the upper body and we've got more integrity of the joint, what opportunities does that create around the park? If we're better in rucks and moors or in the tackle because we're just better prepared up a body, we can move in different ways and we've got confidence to move in different ways, then that potentially allows our players to do things that other players can't, which I think is an interesting opportunity. If we have higher levels of proprioception, then we're better able to transfer forces generated approximately to the distal components of the body. So if we can, if we have better proprioception around the shoulder, we can transfer forces out effectively or we can stabilise forces in better positions. So we're generating a huge amount of force in a hip, it's coming through from the chamber, winding up the force, and if the shoulder is the weak link because we lack the more noise control and dynamic stability, which one's going to go? Shoulder's an easy one because, again, of the architecture of the joint. So what I'm saying here is that we need to improve proprioception and we need to improve our ability to integrate that shoulder into full pattern movements to be able to then amount and manage forces that we're going to get in a rugby match. What we do for an injured shoulder is perfect. What we look at is we get an established range of movement, improve neuromuscular control, integrate it with a ketic chain. Those are our principles from a rehab perspective. As soon as that player then is uninjured and returns into a strength and condition environment, we get all of the stuff that we did from a shoulder perspective to actually make it high performing or to get back to a point. We just go get back in gym and let's get strong, that's what we do. But these principles are well established in the literature and they work from a shoulder perspective. Where the physio bit kind of stops and SNC starts is a gap in the middle of how do we continue to scale robustness and what tools do we have. And I think that's where we lack in the strength and condition environment. We just aren't equipped to scale stability. The other thing that's interesting around, like say we take the hand balancing perspective, hand is on the floor, we're now going to have to move the whole body around the hand and the shoulder. So we're shifting now, that fixing that end position and then I'm going to have to move my hips and my core on my shoulder and if I can get into a handstand and I can hold my body position straight, I've got shoulder stable, I've got all these benefits from a closed ketic chain perspective but I've also integrated that into a ketic chain. You can't do a well controlled handstand unless you can synchronize some of this stuff. Can you create strength at end range? Can you create neuromuscular stability at end range? So the handstand, as we said before, is just a by-product, potentially, of what I actually want, which is stability at end range. It's just a way of getting it. It doesn't have to be about a handstand for us, but for the athletes, that kind of teaches handstand. That sounds cool, a bit different to the shoulder presser. So they buy in and we get engagement and adherence towards it.
