Per this CNN article, brisk activity of as little as 10 minutes per day can improve memory and executive processes, such as planning and organizing, as it increases your heart rate and breathing (which causes your body to take in and distribute more oxygen than when you are in resting state).
Imagine how much better that brisk activity would be for you if you partner it with 4x the oxygen!
At Gym For The Brain, you are riding an exercise bike for 15 – 20 minutes, to get your heart rate up, while breathing 4x the concentration of oxygen you normally get.
The benefits to your brain and body are significant.
