We compare simultaneous Apple Watch recordings from the bar and the wrist against a linear encoder during deadlifts: what changes in the signal and what we can conclude.
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.
Traditionally, strength-training programming has been based on three key variables: sets, repetitions, and loads (for example, a % of 1RM or a fixed number of
Strength training measuring execution velocity is here to stay. Measuring velocity or jump height improves the quality of your services; it allows you to optimize
In this article, I share — from a technical and reflective perspective — the learning and development process behind the latest optimization of the Spleeft
Apple Watch Series 12 is our early pick for the best all-round wearable for 2027. Here is the evidence, the battery-life trade-off, and who should choose it.
If you train long enough, most “new” exercises eventually feel like remixes of things you’ve already done. Dumbbell pullovers are the rare exception. They look
If maximal strength is your “one big punch” quality, aerobic endurance is everything that happens after the first punch. It’s your ability to keep moving, keep thinking
If you coach in 2026, you’re basically living inside a wearable marketing war. Apple Watch promises health, ECG, and VO₂, WHOOP promises strain and recovery,
Every coach knows this athlete. Athlete A looks smooth in warm‑up, can run all day, barely breathing, but when it’s time for a brutal 10
Most training plans are written like weather forecasts made a month in advance: they look clean on paper and then reality shows up with its
