First established in the landmark 2009 study, brain endurance training (BET) has been shown in fMRI brain scans and numerous peer-reviewed studies to improve athletic performance by targeting the part of the brain responsible for managing fatigue, decision making and the suppression of undesirable impulses aka will power.

Frequently asked questions

How does playing this game help improve my mental toughness and athletic performance?

Playing the Mental Toughness Challenge targets the part of your brain responsible for impulse control aka willpower and the perception of effort which has been shown in studies to limit athletic performance. By adding more mental load to the brain either during or after training what the science has shown is that it will create an adaptation in your brain allowing you to push harder and have greater resilience to mental and physical fatigue. For example, Research done in 2015 by Rewire’s chief scientific officer, Walter Staiano showed that brain training is highly effective in improving endurance performance when combined with traditional physical training. Those in the brain-training group had a 3x improvement in time to exhaustion (TTE) than the control group (+126% compared to +42%) over a 12 week training period. This translated to an adaptation in the brain training group allowing them to go 5 min longer on an all out time to exhaustion test over the control group who gave up sooner.

How long does it take before I see improvement in athletic performance and how many times per week do I need to do brain training?

Typically it takes 4-6 weeks of consistent training 3x per week. Depending upon the workout the brain training sessions can take between 15min – 60min

Do I have to do brain training while in front of a computer?

No. The Rewire system has been designed for the high-performance, time-crunched athlete and can be used during training with a variety of sports including: cycling, running, strength training, rowing and many other team sports

How does the system work during training?

The Rewire system includes a set of wireless brain training buttons and straps that can be held in the hands or attached to training equipment like a bike, rowing machine, etc. The Rewire app includes both audio and visual based cognitive tasks that you can use during workouts by tapping the brain training buttons in response to the cognitive questions

Does the app pair with heart rate monitors and power meters?

Yes. The Rewire system pairs with standard bluetooth heart rate monitors and power meters. During the brain training workout we compare your objective data from your HR strap and or power meter with your cognitive performance metrics in order to track your adaptation to brain training over time.

Does the app connect with Strava?

Yes we connect with Strava as well as Oura Ring, Apple Health and Google Fit and other platforms coming soon
