There are always two camps arguing about conditioning, one that says aerobic work kills speed, and one that overdoes the volume. Then you’ll get the crowd that says “aerobic and anaerobic aren’t separate” and turns it all into a semantics battle. ...

Your sport isn’t different. every athlete benefits from consistent strength training. Not to “bulk up,” but to improve output, preserve tissue integrity, and enhance training density. Strength training can increase tendon stiffness, improve intramuscular coordination, and ...

You’re not more “functional” for avoiding machines. You’re just neglecting a tool. Isolation doesn’t mean irrelevant. Fixed paths don’t mean ineffective. Machines offer control, consistency, and a low-fatigue way to target tissue, especially when you’re managing joint stress, ...

I hate these ‘good vs. bad’ sprint form videos. It’s rarely that simple, especially when you don’t know the athlete, their sport, or the context. Everyone wants to argue frontside vs. backside like it’s a binary opposition, but they’re often missing the point. ...

Too often we throw around the word “explosive” without any context. In some instances we are talking about time to force application, or how long it takes to generate force in different tasks. And not all “explosive” outputs exist on the same timeline. ...

Like anything in training, different modalities create different muscular and tendon adaptations. A well-rounded program understands this and accounts for contraction types, rep ranges, movement speeds, and loading strategies to drive the adaptations you actually want. ...

Speed doesn’t exist in a vacuum and neither do the other biomotor abilities. Too often we compartmentalize qualities like strength, power, and endurance without acknowledging their overlap. sprinting, running, and jumping are forms of strength training. They involve high forc ...

Resisted sprinting can be a great tool to improve accel mechanics, but how you use it matters. The type of resistance, load, direction of force, etc - More resistance isn’t always better - Not all resistance creates the same effect - You can (& should) try to make it precise ...

Thread ⬇️ Most people focus on things they can’t change, genetics, limb lengths, but That’s the easy way out. The key is understanding that different training methods produce different adaptations ...
