Now imagine getting this data automatically.
Every set. Every rep. No filming needed.
Video analysis can estimate tempo — but it can't detect bilateral asymmetry, measure at 100Hz, or work without setting up a camera every set.
TENSIO
The first wearable built for lifters. Launching on Kickstarter June 2026.
Video-based analysis is an estimate. Camera angle, lighting, and exercise type affect accuracy. Tensio's hardware tracks at 100Hz with IMU sensors for precise, automatic data on every rep.
