Isaiah Rivera, pro dunker, and John Evans discuss anything related to maximizing athletic performance, and in particular, jump training. Strength and conditioning, jumping technique, weight room practices, and general fitness and health tips and advice are shared on this podcast.
Jump technique is the fastest way to add interest to your vertical. Me and John have preached, like, focusing on good jump technique for years, and there have been people who say technique isn't that important. Other people are on the other side of the extreme. I have evidence that we are right, and it is looking at Dak's world record vertical jump 53 inches. And we're gonna look at his technique when he first jumped 50 versus his technique jumping 53.
Speaker 1:And I think this is pretty fascinating stuff. So having said that, first, John, do you wanna look at the you wanna see the bad jump or the good jump first?
Speaker 2:I wanna see the bad one. Show me the bad one. Alright.
Speaker 1:So I'm gonna play full speed first. This first off,
Speaker 2:this isn't bad. This is, a 40 to 50 inch jump. But
Speaker 1:Yeah.
Speaker 2:It's worse than 53. Oh, wow. Play it again.
Speaker 1:Oh, gosh. I actually want to play the good one right
Speaker 2:next to this one. Play the yeah.
Speaker 1:So just just burn this into your mind.
Speaker 2:I'm trying.
Speaker 1:I'm gonna play it one more time.
Speaker 2:Yeah.
Speaker 1:And now let's look at
Speaker 2:Just visually, you can just see the difference, but it's, like, hard to it's gonna be hard to explain. Yeah. It just looks way better timed. The timing is really where you see it. Yeah.
Speaker 1:To me, it's Like, the Supplies the timing. Three steps. Like, he starts building speed from the first step, and then he just accelerates the whole way.
Speaker 2:Go go to
Speaker 1:And then this position? Man, I wish I
Speaker 2:could stop, like, pause at each frame. Go to toe off. Oh, yeah.
Speaker 1:Look at that. That's crazy. Let's compare let's compare both the positions, actually.
Speaker 2:So just wanna you're do a screenshot that, or you're just gonna oh, you got two frames? Yeah. Oh, Zoinks. Yeah. That's way different.
Speaker 2:That's a that's like a one foot jump. Yeah. Looks like he's about to do a one foot jump. Yeah. That's way better.
Speaker 2:So go go back to the other one. Click back and forth one more time. Yeah. So you can definitely tell he's got that foot tucked, and he's not kicking a soccer ball. He's driving the knee.
Speaker 2:Think that's a
Speaker 1:big one. And that's that is the biggest difference, this
Speaker 2:front leg. That's really where you see, but his posture is also different. Like, he's kind of leaning back in 2022. And in 2026, he's got, like, a little bit more of, like his whole posture is not in that kind of lean back position. He's like you know, it kind of looks almost like a bound.
Speaker 2:Like, he's bounding into it, which is kind of what we say. You gotta jump off that stride. But I think he's it looks yeah. This one looks like he's, like, kicking a soccer ball. And his postural position go back to the other one.
Speaker 2:It's like his his, like, pelvis position is different. Like, that looks, like, good. Like, you can tell. He's got, like, a nice forward lean. He's got good spinal, you know, head neck shoulder upper back lower back pelvis.
Speaker 2:That posture is like solid. Like, he looks like what I would expect with like an upright sprinter or someone like pushing in really hard. You know what I mean? Yeah. The knee is driving forward really aggressively.
Speaker 2:He's not kicking that foot out in front of him. He's getting a good extension out of the back leg. You can tell he's, like, accelerating well off of it and go to the other one. He's got a pretty long split too. Yeah.
Speaker 2:This one, he's, kind of picking his his, like his posture just looks completely different. I don't it's it could just be the angle, but it do you see what I'm kinda saying? Look. It almost looks like his pelvis is rotated forward and upward. Yeah.
Speaker 2:And I think it's because his femur, he's, like, literally kicking his plant leg
Speaker 1:upwards? He's, like, he's
Speaker 2:reaching. Yeah.
Speaker 1:Yeah. Instead of pushing.
Speaker 2:Instead of, like, pushing and driving his knee. Yeah. That is exactly what I was trying to say, but could not explain.
Speaker 1:And he's reaching while and then the angle he's reaching at is, like, like, he's he's he's, like, almost, like, looking up.
Speaker 2:Yeah. He's, like, leaning
Speaker 1:up and, Like, like Yeah. His chest is more is pointed more this way.
Speaker 2:It looks like he's getting ready to set up a one foot jump. It looks like he's getting ready to set up a one foot jump.
Speaker 1:Oh, yeah. Yeah. Yeah.
Speaker 2:It looks like he's gonna keep leaning back, and that he's gonna you know, his hips are gonna come forward. Like, hips are that's what it is. His hips are coming forward. Like, they're coming forward like a one foot jump, you would expect to see. But in this one, go to the other one.
Speaker 1:Versus this, you could not loaded up. One foot jump.
Speaker 2:Yeah. You cannot one foot. You would die. Like, you can tell he's gonna have more flight time in that position to reposition. Like, he's gonna get flight time out of that.
Speaker 2:Yeah. Reposition. It's right there. Even, like, this frame. Elastic is shit.
Speaker 2:That's crazy. You're going mid flight?
Speaker 1:Yeah.
Speaker 2:Oh, that looks like a one foot jump. Look how late like, that looks like he's gonna one foot jump, and then he starts to reposition.
Speaker 1:Yeah. Still gets knee to knee.
Speaker 2:Yeah. Go go back, though, to mid flight. Go back. No. Go back.
Speaker 2:Go back. Back. Back. Go forward. Forward.
Speaker 2:Back one more. K. Go to each of the frames. Let me see.
Speaker 1:The other jump?
Speaker 2:Yeah. Go to the other one. Back and forth.
Speaker 1:Okay. Okay.
Speaker 2:Yeah. That's much more truncated. It just looks more truncated. Like, he's not pushing as hard. He's not driving his knee.
Speaker 2:He's kinda swinging the foot out
Speaker 1:in front of him. Short
Speaker 2:and choppy. Looks like short and choppy. One of the things I've always seen with the highest jumpers, fastest sprinters I've ever seen, best long jumpers, is they can do really big positions very, very fast. They can hit big positions insanely aggressively with violently. It is a violent activity over big ranges of motion.
Speaker 2:That's like what you see. And in this one, it just looks it's still open, but it looks more truncated. It looks more short and choppy kind of and like Yeah. Jabby almost, which you don't really wanna see. You know, high jump is maybe kind of not even really the exception.
Speaker 2:There's like a certain position that happens in speed jumpers with the the free leg coming back behind them and repositioning. But like in this in two foot jumps, you could just tell like that foot is right underneath his hip on the penultimate step, and you just he just pushes violently off that step. I don't know where he's planting here. Yeah. It's like a stutter.
Speaker 1:Yeah.
Speaker 2:It's like he's setting it down and, like, stepping as opposed to, like
Speaker 1:These So in collision. These positions are pretty similar.
Speaker 2:When you when in a still frame, yes. But if you look at the velocities, I think they're very different and the timing.
Speaker 1:Where you see the biggest difference in my opinion is when you go to the good jump, it's just the first Like the rhythm. Two strides. Like, one, two. So when he takes left and right, and then that
Speaker 2:an ultimate step is ends up being that's what I'm saying, like, the timing velocities, the way he's contacting the ground. In a still frame, it looks very similar, but it it's the timing and the velocities that he has while he's hitting those positions is way different. Like
Speaker 1:And look at the arms. How how much more aggressive do they momentum. Oh, yeah. Look at the arms right here. Yep.
Speaker 1:Right? So, like, right before the foot hits the ground. Let me see. Something that's interesting actually that I didn't realize Has he
Speaker 2:switched to a circular arm swing?
Speaker 1:No. Look. So his arms peak at their like, the shoulders are most extended right here, like, at touchdown.
Speaker 2:That's what I do too. I get That's crazy to say.
Speaker 1:But I'm the most extended, like, here. Really? Yeah. And then as the block foot's repositioning like, look. His block foot and arm swing aren't timed until the very end.
Speaker 2:Yeah. But I think that's when
Speaker 1:it hit
Speaker 2:the most.
Speaker 1:Dang. It that's weird. They end up timing.
Speaker 2:That's what I'm saying.
Speaker 1:Yeah. The block is they end up timing.
Speaker 2:So I do something similar. I pause, and then I swing through as my block foot hits the ground. Like, I kinda do what he does a little bit.
Speaker 1:Yeah. No. Mine's like I'm like at max extension like back here. Like, my arms are already Yeah.
Speaker 2:Do you hold that position until your block foot starts to come through?
Speaker 1:I think so. Yeah. Because I mean, I'm in flight for a while on the Penultra.
Speaker 2:So your flight times might be a little bit different because he's got stiffer tendons, so he's gonna have a more elastic collision with the ground. I think that's why he gets so much out of that jump compared to this jump. Like, his his RFD is you have to have both. You have to have crazy stiff tendons and crazy RFD, and he does. So, like, that jump, I think, is less elastic like this one.
Speaker 2:Yeah. But if you go back to the other one, it's like he's colliding with the ground, bro.
Speaker 1:You know what I haven't done?
Speaker 2:It's like everything is hard on time. Oh, he's really long in this one, isn't he? Wasn't he crazy long in that one?
Speaker 1:It like it was like three five.
Speaker 2:I would assume that I would assume he's gonna be less than 300 in the ladder jump.
Speaker 1:Alright. I'm about to I'm about to do it. Do you wanna pause it?
Speaker 2:I can I wish I could kind of scroll through it? I can I can talk while you while you do it?
Speaker 1:It'll be quick, like, some things off the top
Speaker 2:my head. But I do wanna I do wanna mention this about, like, positions. If you guys are ever watching, like, a still frame of a position, that's not necessarily the the end all be all or tell all. Like, you really need to look at it full speed. And sometimes, damn what Pathway actually says, watch it backwards at full speed.
Speaker 2:And don't just watch things in slow motion. Watch them at, you know, 1.2 times speed. Watch them in 1.2 times speed backwards because what happens is we create a bias of what we expect to see. But then when you watch it backwards, Dan would say, like, you remove that bias. And I do think there's some truth to that.
Speaker 2:Like, if you're only watching one type of one one you know, you're only looking at one frame if it's always a still or something like that, it can be very misleading. And I found that in speed jumping a lot of times. My rhythm is not the same. My timing is not the same. So you have to have a good coaching eye and create a framework of what it should look like timing wise and then try to assess what you're seeing with your eye compared to what a good jump looks like in your head.
Speaker 1:So his r his RSI you wanna know his RSI or flight or contact
Speaker 2:time first? Tell me his contact time first, then I'll notice
Speaker 1:Point312.
Speaker 2:Point 312. What was it the first time? 35? Yeah. But his RSI is what?
Speaker 2:Probably, like, 4? 3Point26. What's your RSI?
Speaker 1:Like, 3435.
Speaker 2:Oh, that's interesting. That's because he's he's gotta be so much lower. Like, he's gotta be low as shit in these jumps. Not really. Go go back, dude.
Speaker 2:I I bet you he is. I bet you he's deforming. If I had to guess, not that one. Go to the go to the other one. This one.
Speaker 2:He's he gets low, dude. Yeah. Look at look at his knee flexion.
Speaker 1:That is crazy. That's not wildly different.
Speaker 2:Go back one more. Go back one more. Go back. You know what it is? Keep going back.
Speaker 2:It's how much translation forward his pelvis comes and how far his knees rotate forward. So he contacts there, but, like, look how how many frames his knees are just moving forward and downward.
Speaker 1:Yeah.
Speaker 2:Like, think about doing a jump where you're, like, actively, like, pushing your knees downward and forward. Yeah. Like, he's not, like he's, like, building tension, like, lot of tension right there. That go back one more. One more.
Speaker 2:Back. Back. Back. From there, go forward. Forward.
Speaker 2:Those three frames back and forth, you can really start to see how much yeah. See how much it's like his knees are rolling downward and forward and he's really, like, loading the hell out of his quads there? Yeah. I would assume that's probably, like, him trying to max out impulse. Like, he's just trying like, tension's still building in the muscle and the tendon, you know Yeah.
Speaker 2:At that point. And he probably can't do that super like, to jump that high, you need so much impulse. So it's like during the concentric side that he's trying to get as low as possible to have, like, as much pretension and as much impulse time to push upwards as possible. Like, you gotta be insanely strong in that position. Mhmm.
Speaker 2:How much is his block foot coming off? Go back one like, frames. Look at his block. Look at his foot. Yeah.
Speaker 2:His left foot. It's like flat.
Speaker 1:It's almost Looks like a pancake. Through it. Yeah. It looks like he just squishes. Yeah.
Speaker 1:He squishes it.
Speaker 2:So, yeah, I think, jeez, it's such a crazy jump. You know what is crazier is how long he comes down. Like, that frame is insane to me where he slaps it, and he's, like, just falling for, like, four frames afterwards. Yeah. Like, is this your video?
Speaker 1:Yeah. Yeah.
Speaker 2:That's pretty cool. No one else has this video. So, yeah, big pictures, big takeaways here. I'd say, like, technique definitely matters. I think you can see that, like, firsthand with Dak.
Speaker 2:Maybe don't drive the knee, get a lot of momentum, push yourself downwards and forwards. He doesn't really Rhythm.
Speaker 1:Big steps. Rhythm. Every every step was big, aggressive, had intent, and it accelerated through the entire and big split on his penultimate, lead with the knee.
Speaker 2:That's a good way to put it. Every step is bigger and more aggressive and more violent than the last. All the way until takeoff and through takeoff. It shouldn't feel
Speaker 1:like it's big short. He's a freak athlete because his basement was 50, basically, with shitty technique.
Speaker 2:You know, it's like people are like, could he jump higher with good technique? Yes. Remember him jump higher with good technique?
Speaker 1:Bro, I
Speaker 2:remember him
Speaker 1:one stepping twelve one forty eight inches
Speaker 2:for him. Freaking Like Yeah. A cyborg.
Speaker 1:He's a cyborg. I gotta dip.
Speaker 2:He's gotta go.
