Improving Spleeft’s Barbell Velocity Algorithm with Real Data
How I used Apple Watch data, a linear encoder and recordings from Paris to improve Spleeft’s rest detection, repetition segmentation and bar velocity tracking.

Smart Zero improves repetition detection in demanding lifts, while new Apple Watch controls, raw-signal review, and additional VBT metrics give coaches a clearer and more flexible workflow.

Over the past few months, we have been working on three new features: detailed AI summaries of your athletes’ training sessions, synchronization of these summaries

0. For those unfamiliar with Velocity Based Training Velocity Based Training (VBT) consists of monitoring the execution velocity of repetitions performed with maximum intent to

In this new Spleeft update, we have focused on two fundamental aspects: improvements in the user experience regarding execution velocity measurement and an expansion of

Spleeft continues to consolidate its position as the hub for VBT data At Spleeft, we continue to move forward with a very clear idea: to

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.
