@nspsoccertraining: This posts purpose is to show the science behind how the body uses 3 different energy systems to fuel performance. By having an understanding of this, you can create more effective training sessions, and reach your fitness goals faster. Obviously nutrition goes along with this. Without proper nutrition your body won’t recover properly and the benefits from this type of training will not be seen. Playing football trains all 3 energy systems, but if you don’t have access to regular games, this will really help you. #footballfitness #footballers #soccerfitness #soccerfit
