Your arms don’t stay locked at 90° while you sprint. That cue has survived for years because it’s simple and easy to say, not because it reflects how sprinting actually works. If you watch elite sprinters in real time or slow motion, you’ll see the same thing over and over…

Two athletes sprinting, two different movement solutions. The goal isn’t to copy a track sprinter frame by frame. It’s to understand the principles behind why the fastest runners hit the ground closer to their hips, get off the ground quicker, and organize the pelvis and leg

You don’t need to toe drag. Most young athletes try to toe drag because they’ve seen it in some elite sprinters and assume it’s the cause of speed. That’s the first mistake. Actively dragging the toe doesn’t help you accelerate. Creating friction against the ground outside

They used to find the fastest man in the NFL by actually racing. No debates or hypotheticals. And even with no force plates, no resisted devices, etc. they had legit speed. Bring this back!!

Maurice Greene ran 6.39 in the 60m and 9.79 in the 100m. At the time, he was one of the fastest humans to ever live. His training wasn’t anything crazy. It was structured, repeatable and executed with intent. Here’s what it looked like Upper body (Tuesday / Thursday) – Bench

The problem isn’t that we don’t know what works. It’s that too many programs still avoid it… This is Ajax training in the 90s. Drills into sprints. Bounding. Resisted runs. Stair jumps. Strength work. Agility. No gimmicks, they were training off principles that still hold

Olympic sprint and jump coaches were surveyed on the plyometrics they use most with their athletes (Loturco et al). These four kept showing up. The main reason? SPEED development. Each one fits a different contact time, a different mechanical demand, and a different part of

Plyometrics aren’t just for jump height or sprint speed… In this study on 5-km runners, all groups completed the same weekly running volume. The difference was what supplemented that running. - Running only → minimal improvement - Running + squat jumps → large improvement

I made this video last year, and it’s worth a reshare as it’s still relevant today. As college athletes start coming home for break, we keep seeing the same issues. Speed and acceleration are either missing, underdosed, or treated like an accessory. Not enough exposure to

In a study of elite US 100m sprinters, step length was the single strongest predictor of maximum velocity, accounting for nearly 45% of the variability in males and 40% in females. Contact time wasn’t significantly correlated with velocity at all. Bolt is a great example.

You don't need a gym or equipment to perform effective plyometrics for speed training. I write workouts for my athletes to complete at the track or outside all of the time.

Many don’t think much about the soleus when they talk about speed, but we probably should. In acceleration, estimates have put soleus force around 8.4-10.7 x bodyweight. At max v, it’s still around 7.3xBW. So the calf complex is under serious load in sprinting. And it’s

3 Sprint Myths That Won’t Die 1️⃣ “You run on your toes.” You don’t. Sprinters strike through the ball of the foot with a dorsiflexed, pre activated ankle that’s ready to handle force. The heel drops slightly to load the Achilles for elastic recoil… it’s a reflexive,

Running fast is not the same as sprinting. A lot of training lives in the gray zone. 70…80…90 percent effort. Volume builds. Athletes feel prepared. But sprinting doesn’t scale up gradually. The biomechanics change abruptly as athletes approach maximal velocity.
