General physical preparedness (GPP) is an indelible part of the exercise regimen of any physically active person. GPP is the foundation of training in any sport. The effect of GPP on a person’s physiology, and in particular muscle flexion, neural and humoral regulation, is the object of a wide array of studies, all of them supporting its fundamental significance. Play Reha offers you a program that includes a balance of all muscle groups, is suitable for any age, and has a carefully planned, gradual difficulty curve.
