Not only is this completely wrong, but it’s negligent and potentially harmful. An isokinetic dynamometer is the gold standard for assessing force production and how quickly you can produce that force, which is vital for reducing the risk of injury. A single leg squat doesn’t come close to reproducing...

I use as many tests as I can.

Only reason why it's gold standard because how expensive it is. The person who makes the Golden rule holds the gold. Simple test that measures the distance and grading the landing jump can also prevent injury.

The original video makes total sense, you wanna test a movement test it functionally, not by expensive product researchers use. Not to mention their outstanding clinical experience 😉

My favorite part of the isokinetic testing in the video is the improper set-up. Let me know if you see it.

PRIORITIZE SINGLE LEG STRENGTH❗️ Squat & Deadlift do NOT always have to be your main lower body lifts. There are plenty of ways to get strong. Here are some MAJOR benefits of prioritizing single leg lifts: 1️⃣ Exposes strength & balance inefficiencies & inequalities. Strong on 2 legs doesn’t mean strong on 1 leg.. Strong on each leg does mean strong on 2 legs. I’ve seen enough strong squats & deadlifts get buried with single leg exercises. Typically isn’t true the other way around. 2️⃣ Less back pain. Regardless of their technique, some athletes experience back pain from squatting & deadlifting. YOU DO NOT NEED TO SQUAT OR DEADLIFT TO GET STRONG… Single leg exercises can alleviate that pain. Less load, similar intensities, similar benefits. 3️⃣ “Sports are played on 1 leg.” I’ve heard this plenty of times and there is definitely a ton of truth to it. Movements are very single leg dependent. Sprinting, stopping, changing direction, jumping, landing. Single leg training can be the key to higher performance and less risk for injury. 4️⃣ Less learning curve. Beginners can immediately reap the rewards of single leg training because of how easy it is to implement. Something as simple as sitting on a bench and standing up using 1 leg is challenging for someone who has never done it. No bar on the back, no picking up weight, no teaching hip hinge.. Simple single leg training will buy athletes time to train while simultaneously improving squat and deadlift technique.

Knee cave is good for glutes? 😱 This video is bound to upset some people. A new study directly examined knee cave a.k.a. knee valgus vs pushing knees out in a squat on muscle activations# well as forces acting on the knee The researchers found MORE glute activation when the participants cued knee cave vs knees out where they saw more adductor activation. This may seem strange since a lot of exercises for the glutes utilize knees out. But these are typically exercising involving abduction, not squats Not only that, but they found the forces on the knee during knee cave were not even close to the level required to cause knee injury I am NOT saying you should purposefully valgus, but if you have strong glutes & you find that your knees naturally track in during heavy squats, you are probably better off training all your sets that way so that those tissues appropriately adapt, rather than squatting how you ‘think’ you ‘should’ on lighter sets only to have them cave in on heavy sets A perfect real life example of this is my friend Lya Bavoil, current world record holder of a 225kg squat in the 69kg class (496 lb squat at around 152 lbs body weight for my Americans who hate math) drug free. Her knees have always caved during squat. This is likely BECAUSE she has such strong glutes (she also deadlifts well over 500 lbs) so her body naturally goes into the position where she is strongest. She’s also never hurt her knees 🤷🏼‍♂️ If you don’t knee valgus naturally during squats don’t make yourself do it but if you find you still have some knee cave even though your glutes are strong, I wouldn’t worry too much about it unless you consistently find it painful It’s time to let go of these dogmatic ideas around ‘perfect’ form. Perfect form is the form for the INDIVIDUAL that allows them to perform best without pain DATA>your feelings

Thank you Bryan Johnson. Jefferson is amazing. I will try to summarize the general dunk formula right now: 1. Height is a huge factor 2. Genetic jumping starting point 3. Age and injury history Then I would say 2 main things go missed: 1. Not being able to palm a ball is a huge barrier - not only to putting the ball through the rim, but holding back the JUMP INTENT itself. A small or foam ball (and even low rim if needed) can be a breakthrough to BECOMING A GOOD JUMPER. Getting well up over the rim is the first step and you can get better quality jumps without holding a ball. 2. A full squat. Think Wemby, 7+ feet tall, no chance genetically to be an Olympic weightlifter but then the top Olympic weightlifter of all time, pound for pound, is like 5’5” and no chance blocking Webmy’s dunk - and so FULL SQUAT tends to go missing! It gets overlooked. But I’ve seen NOTHING come close to how much it SUPPORTS dunk goal, because it strengthens legs AND KNEES. It’s almost like the worse you are at full squat, the more potential is waiting for you. For dunking, knee is NOT #1 power but knee PAIN is #1 BARRIER. Even in pro dunking you’ll now find the majority full squat. I personally coached many of them 8 years ago and it changed dunking, behind the scenes, forever. I’m not saying to work through pain. Here and on a weekly basis I post pain-free full squat strategy. 3. Similarly, seated calf machine goes underrated for extra Achilles support. So if we recap: Dunk is largely your starting point you can’t do anything about. But you can do a LOT with uninhibited jumping - that means neither ball nor knee pain or Achilles pain holding you back. Then, yes, any other power method is valid and can further boost! Doesn’t help that from 1970s to today, in many textbooks, “NO KNEE OVER TOES / NO FULL SQUAT” was forced on millions of students, despite no long-term research, which now shows that mistake.
