I guess we're oldies here on Popular Airsoft to do Crossfit training, but for the young ones, they might want to try this as it will keep them fit, military-fitness speaking. Golandec Airsoft show the training they do... "We are all working common office work, usually sitting at the computer and looking at the monitor. Therefore, we try at least to give ourselves some training to keep fit. Therefore, we have introduced a symbiosis of fitness and power load on the basis of airsoft. The challenge is to increase endurance team member. We called it 'Airsoft Fitness'."
