Hi.
Recently I've spent some time watching YouTube interviews with Dr. Stuart McGill on back pain.
At one point in an interview with Chris Williamson he answered a very interesting question. Chris asked if its theoretically possible for an individual to train to be both an advanced Yogi who has highly stretched out flexible muscles and to also be a master power lifter who can lift very larger weights.
To my surprise, McGill answered that this is a physical impossibility. He explained that to be able to lift a heavy load, or to perform any major physical movement in a sport (pitching in baseball, punching in boxing, jumping in basketball, etc.) the relevant muscles must be very stiff in order to act as springs so the athlete can perform such a powerful physical move at high velocities.
He explained that stretching out these muscles as far as a yogi would as part of his practice must necessarily come at the expense of athletic performance. This came as a major surprise to me because I had just always assumed that more stretching is better and that more stretching always make you stronger, all things held equal.
But McGill also said that most people aren't extreme athletes and don't need this kind of performance. For them who just want to live healthy lives, that they just need some sweet spot in the middle. I figure kettlebells are good for that.
For this who are interested, I used ChatGPT to transcribe the relevant conversation from YouTube audio into text and I copy it here. I strategically inserted commas into the text because this is long form conversation.

Chris: So we've touched one of the things that you come up with a lot is the relationship between stiffness and flexibility in the spine, would it be possible to have a yogi who's also a powerlifter
Stu: No, you asked me could they be a power lift or a yogi, let me say why I said that and very emphatically, have you built a world-champion power lifter
Chris: No
Stu: Do you know one with loose hamstrings
Chris: yeah they don't exist
Stu: So yeah I mean the the strongest power lifter has to have tight hamstrings it's non-negotiable, so there you have it, now a power lifter needs to fight their mobility to get down into a proper deadlift pull, there has to be elastic tension in their body to assist the muscles in the pole if you're gonna win the worlds, so they wear elastic suits to add even more stiffness to allow even more elastic recoil, so I mean but we're going to for the extreme here, is that healthy or is that a great athlete, or is that what you want, I mean that's debatable but let's go to the other end, I've had Yogi's who are on the TV teaching yoga yoga as patients, I can't really think of too many who are strong, in fact they can do wonderful squats, their bottom can go right down and touch the ground but they have difficulty doing the bodyweight squat to stand back up again
Chris: Is that so?
Stu: Oh yeah, now somewhere people want to be in the middle, you know Yogi's aren't out there on the rugby field, nor is the power lifter, so that rugby player somewhere in the middle, or the crossfitter has to be somewhere in the middle, and that's the expertise of first of all the dumb luck of choosing your parents, and then being as clever as you possibly can in creating the right adaptation, I mean I'll ask you some other questions, the NBA championships are on right now, you see a lot of people dunking basketballs, do you think they have loose hamstrings?
Chris: No
Stu: I'm one I'm one of the few who've measured them, no they're tight, they bounce off like Springs, so you know you you went to this dark place of saying oh well they're stretching programs to create more mobility, be careful now, go through the great athletes you've measured and tell me who has unlimited mobility, they don't, they're elastic athletes, they're wound up Springs, so you know you can go through the spectrum from the throwers to the golfers to the tennis players through to the Olympic weightlifters, I'm talking about elastic athletes here, what a mistake it is to stretch away that elastic athleticism
Chris: It's that the way it works, are the two counter to each other, you've got stretching and then you've got progressive overload, and you've got loading, and those two are they about as antagonistic as you can get?
Stu: Yeah you're talking extremes, um maybe in some people, but again my world is elite athletes, I have to tune the Machine, I'm tuning elasticity, I'm tuning fascial trains, I'm tuning muscle pulses, I would be very judicious in whether or not we would stretch them away with the static stretch, so we might do a static stretch say for a rower, who now has a lot of posterior annular disc stress, they've just done a rowing session in a boat or on owner ERG, and I would say good lay on your tummy and just breathe now, there that is a static stretch for a rower, now I might do a thoracic extension stretch to give them more elasticity so they're sliding up the slide on the seat on the boat they go into compression and the catch and then the hips and knees start to extend and then their spine as they sit tall gets a little bit of a whip as their hips explode and really whomp you can hear that elastic storage and recovery in the fastest boats, so you know look at the people who throw a baseball 110 miles an hour, are they heavily mobile, well they are asymmetrically mobile on one side, but they have a hell of an elastic, you know the first elastic across their hips, the second one across the front of their chest, and the third one in their in their wrists, you put those three elastics together and you can throw on it 110 miles an hour, if you don't and then all you have is mobility, you won't throw a ball very fall, do you know Yogi's who can throw a ball 110 miles an hour, do you know a power lifter who can throw 110 miles an hour, have you measured the great golfers
Chris: How strong are they I'm not sure have you tried?
Stu: Well I've measured them, how much effort, have you ever tried to hit a golf ball a long way?
Chris: Yes
StuL Okay you noticed it didn't go very far
Chris: No
Stu: It foes further when you don't try, so when you have a muscle pulse of about 40 to 50 to 60%, that is the sweet spot for speed, because when a muscle contracts it creates force it also creates stiffness, if I maximally contract my bicep I can't punch you, I've got to really boom I got to let it go, when I measure the guys who hit the hardest in the MMA like the UFC for example, do you think it's the guys with a great big muscle, no they pushed their punches, it's the guy who can snap BAM that hits the hardest, so it's a neural priming of a spring that is then released, now we've got a lot to talk about in terms of optimal athleticism so let's be a little bit careful now when we talk about static stretching to enhance injury resilience and athletic performance because in the great athletes and I'm not talking about duffers here, I'm talking world-class people, be very careful with stretching
