Both matter. Isometrics can help improve force production, tendon stiffness & the ability to hold key joint positions. Plyometrics help athletes express force through faster stretch-shortening cycle actions. For runners and field sport athletes, I don’t see this as an

I'm tired of hearing that aerobic work makes kids slow. Especially in 400 training. The same idea that refuses to let a 400 kid touch a tempo run is the idea that explains why so many of those kids tie up at the 300m mark like they're running through wet cement. "Too much aerobic work would steal their speed." Cool. I agree leg speed matters in a 400. But here's the idea I want dead. The Aerobic Tax. The notion that every aerobic mile withdraws from some imaginary speed account. That tempo runs dull the kick. That a kid who ran a steady 4-mile on Monday somehow can't fire on Friday. That a 400 athlete who builds an engine in the offseason will somehow show up in April with no top end. It doesn't work that way. You don't lose speed because you ran long. You lose speed because you stopped training speed. But more than that. Your kid isn't dying at 300 because he's TOO AEROBIC. He's dying at 300 because there's no aerobic floor underneath the speed. The race is 49 seconds. He has speed for 29 of them. The other 20 are aerobic whether you trained them or not. Pull up the training log. Find the tempo runs. Find anything that built the engine that has to carry the speed across the line. If it isn't there, the kid isn't dying because he ran fast. He's dying because nobody built what he needed to FINISH fast. The 400 isn't a speed event with an aerobic problem. It's an aerobic event with a speed finish.

Do your players actually need more separation? Not always. 👇

Aerobic Power: Ultimate MMA Conditioning
by Joel Jamison I’ve posted this book before. It’s based in MMA, but it can absolutely send you down some rabbit holes that can help with 🏈 players/WRs. 🧵 of some pages that will be useful for you to deep dive on.

When presenting, knowing your content sounds obvious, but it’s often where we fall short. It’s easy to spend time perfecting PowerPoint slides while overlooking the most important part: what you’re actually going to say.

Cross your hands. Now switch them. Cross your arms. Now switch them. One way felt natural. Quick. no thought. The other? You could do it… but you had to think. That’s the difference. Nobody cares how we cross our arms. But we care what a swing or delivery looks like. So what happens when we coach athletes into positions that require more thought and energy? Less repeatable. More timing dependent. Harder under pressure. The goal isn’t forcing positions. It’s finding what’s natural. Different athletes need different solutions. #MotorPreferences | MPE

NEW: Jaxon Smith-Njigba wore a size 12 at Ohio State and had hamstring issues. Seattle switched him to a 10.5 and the problems went away. The Seahawks have been using body scans to customize gear for each player and it’s paying off 👏

A 360 approach @DomReyes

I love promoting KPIs! Might there be better KPIs than squat & clean? How about MPH and TRUCK STICK. Vertical and Horizontal Jumps?

How to spot this easy👇🏻 Jumpers who rely on high relative strength use more knee flexion to generate impulse (they squat deeper). Jumpers who are highly elastic need less knee flexion to generate same impulse. You can profile athletes quickly using Jumps.

This study modeled peak muscle forces across four running speeds and the numbers tell you something important about what sprinting demands. The hamstrings go from 2.10 times bodyweight at 3.49 m/s to 8.95 at 8.99 m/s. The iliopsoas shows a similar jump, rising to 9.04 times

We’re quick to invalidate a squat jump if there’s a countermovement. But how often do we question whether a countermovement jump is actually a countermovement jump? Eccentric peak velocity (EPV) helps assess how well it’s loaded. Watch here 👇 youtube.com/watch?v=ai5BxKKs…
