Much like balancing a bicycle, it takes practice at first. Controlling a hang glider is not strength, but balance, and a light touch. You can strengthen your arm muscles and upper body through hang gliding. Almost anyone can play a hang glider. Perfect for your boyfriend or husband who are amazed by this motorless sports device. For all fans of motorless aircraft, kite flying, slope gliding and hanging glides. Great for anyone who loves flying in the mountains with their hanging glider.
