The air pressure should be adapted depending on the product, sport type, ability level and the weight of the user. It all comes down to personal preference. The air products can be inflated fully for firm bounce and air can be easily released from the valve for a softer feel.
To avoid strains and injuries always use enough air pressure within the products. Also check and refill before every training session.
You can find a recommended guideline with pressure indications in our user manual and below.
