Let’s start with a definition! It’s a bit technical but very interesting to understand!
Proprioception is the set of nervous information transmitted to the brain allowing the regulation of posture and body movements. It is sometimes described as a “sixth sense” of the human being.
The proprioceptive system intervenes permanently to regulate our balance by contracting certain muscles, for example on an unstable surface (soft ground, ice, surfboard…).
Proprioception is therefore closely linked to the notion of balance, which is also essential for surfing! This is also what will allow you to avoid injury by working all the small muscles around the joints, of which we are not very aware.
Recommended exercises to work on proprioception: yoga (example of practice on this link) and balance exercises on one leg or on an unstable surface (bosu, balance boards or gym balls).
