In this article, I share — from a technical and reflective perspective — the learning and development process behind the latest optimization of the Spleeft

Some weeks ago, we published a proof white paper which explaining everything about our algorithm, the technology behind it and lots of data proving why

INTRODUCTION – Scientific Validity After validating and testing with real users the measurement of running speed with the mobile camera (you can read the presentation

INTRODUCTION Quantifying movement velocity is the only way to control intensity and level of effort at the gym. Each velocity is hugely correlated with a

You’ve probably been there. You’re scrolling through your phone between sets, and you see a post from someone saying they did 25 sets for chest

You already know the basics: lift heavy things, eat protein, sleep well. But knowing what to do and actually doing it with the right system in place

Here’s what most athletes get wrong about speed training: they think it’s just about running faster or jumping higher. They show up to the track, do

You’ve probably heard it a thousand times: “Lift heavy, eat protein, grow muscle.” But here’s what most coaches never mention—the actual biological mechanisms that make

Here’s the disconnect most coaches don’t talk about: the difference between doing a strength exercise and doing a strength exercise well. You can watch two athletes

If you coach long enough, you eventually hit that moment: two athletes on the same program, same percentages, same cues… and completely different bar velocities.
