Nothing wrong with bodyweight exercises but eventually you need to overload the body with global strength exercises. Unfortunately people find air more interesting than iron, meaning people are forgetting that overload can be done with fighting gravity. Eventually program variable options will paint you into a corner and you must overload the body. After reading a random entry from a random blog, the phrase there is no substitute for strength, and no excuse for a lack of it struck a cord with me. Not overloading the body is eventually a cop out because all major sports are about power and forces. Bosch has made me rethink strength, but I have come back to the the same conclusions after doing a lot of researching. Technique and progressive and intelligent loading is the key to health, not removing what is appears dangerous. If you shoot yourself in the foot, don’t blame the gun, blame the one aiming.
