Features & Capabilities

Speed4Lifts is a Chrome extension that collects your strength data and, when paired with the Vitruve encoder, enables Velocity-Based Training (VBT). By analyzing bar speed and movement velocity, it provides a live daily 1RM estimate and science-backed guidance without pushing you to muscular failure. Vitruve’s linear encoder delivers precise velocity data to tailor training plans to your current status and goals.

Benefits include reduced injury risk, clearer performance tracking, and fatigue management. Hundreds of coaches use Speed4Lifts to optimize programs and monitor progress over time. Important note: on M1 Macs, the extension visualizes data only; training with the encoder must be done on supported hardware.

Love how easy it is to use but have been using the video feature to send videos to my coach but doesn’t save videos consistently. I haven’t had a time where it’s save each video in my training sessions, I’m lucky if it saves back to back sets. If I try to edit the length of a video in the app, it will immediately delete the video.

The hardware is top-notch, well-made, and functions exactly as described. I was initially concerned that the encoder would feel like a cheap, rushed-to-market throwaway Kickstarter ripoff; these fears were entirely unwarranted. This thing is solid. The mobile app's UX is flawless - intuitive, discoverable, follows the principle-of-least-surprise. I love that I can dump my workouts to CSV with little effort and truly own my data. If you're curious about VBT but feeling a little uncertain as to whether or not the Vitruve delivers on its promises - pull the trigger. You won't regret it. Hats off to the engineering and product teams behind this thing... y'all should be proud of yourselves.

There's many features that could be added (like graphs on each rep) and it will crash very often while you're training. At this point I'm just using the tracker and use the raw data in my training log.
