Scroll down & learn how to train with muscle oxygen

Learn how you can optimise your warm-up, determine your sustainable pace, adjust your position, tackle limiting muscles, or quantify your needed recovery time with our muscle oxygen sensor.



To get your body ready for your training, a warm up is essential.

You can increase the amount of blood flowing to your tissue and increase the amount of oxygen by performing a proper warm up. The images above, show the moment when you reach your maximum available oxygen and are ready to perform at your peak.



Pacing is essential in endurance and interval sports, but how do you determine the best pacing strategy?

With Train.Red you can finally see how your muscles respond to your pace. If the line is 'red' and your saturation goes down, you will not be able to hold on to that pace for long. While a flat yellow line indicates a sustainable threshold pace for that muscle.


Rest smart

How long do you rest in between sets and reps?

Knowing when to start your next set is a game changer. If you want to train endurance, you can start your next set after period 1. If you want to grow your muscles, start after period 2. If you want to increase your strength, wait until rest period 3 is over.


Determine optimal position

Your position has an influence on the oxygen supply to your muscles.

An aerodynamic position on your bike will reduce the air resistance but influences your blood flow. You can compare the blood flow to your lower limbs with a garden hose, especially for athletes with pronounced muscles arching your body will reduce the flow.

We can show how your body position affects your muscle performance in any sport.



Combine up to 4 sensors at once to measure muscle imbalances or limiting factors.

Determine whether it is your left leg, your right leg, your upper leg, or your calf. Know which part of your body prevents you from going faster, higher or heavier.


How do you know what muscle to train?

The fastest way in assessing limiting factors is by using multiple sensors at once. Alternatively, you can repeat the same exercise to detect which muscle needs some extra work.

Quantify if your right leg desaturates as fast as your left leg again after an injury. Or check if you are targeting the right muscles with the correct technique during a difficult exercise.

Learn how your body recovers from an effort and adapt your workouts to train as efficiently as possible. We classify the local muscle oxygenation kinetics and guide you with your endurance, hypertrophy, or strength goals.
