i'm following a workshop to become a gym teacher...we talked about the core strength and how is necessay to develop a strong body with great stability!!!
also we are 38 people at the course and no one can hold a front lever or a planche or a back lever...this can show how much the gymnastic activity and progression give to you a bulletproff abs and back, they ask to me if i was able to hold a planche on the wall with the arms completely extended, the told me that is damn difficult and you need a high level of core strength (think that for them do this position on the elbow at 90° is terrible)...so this is my result...can you do it?!
