Testimonials
Christian Pirri
Athlete & Coach
I use Train Red regularly, on the one hand to make pause control between intervals more efficient but also to control increased SMO2 saturation in the muscle during aerobic training sessions.
Gommaar d'Hulst
PhD (@WOD_science)
The days of bulky, complicated devices are over. Train.Red has broken new ground with user-friendly sensors. It can be effortlessly attached, and the app shows the data in a simple GUI that anyone can comprehend.
Roman Fomin
PhD Director of Sport Science UFC
We (UFC) are taking performance improvement to the next level, using real-time energy systems assessment on both systemic and peripheral levels.
Sarah Thivent
Sports scientist
As a researcher, I needed to measure muscle oxygen saturation (SMO2) during the cycle ergometer tests of my patients. I then discovered Train.Red, I use it every week and it meets my needs very well. It's a simple tool that provides very important information if one is aiming for improvement or research purposes.
