Is it advised for any reason not to do push ups on rings? I've been doing ring push ups for a while but am starting at the beginning of the program because though my strength is ok, my mobility is... limited. (I'm skipping A1).
Also, can I keep doing pushups even after I 'graduate out' of push ups - as a surfer, the pushup is a key movement pattern for catching waves and I'd prefer to keep training that movement pattern even once I'm on to what looks like many months of dips (I'll have lots of questions on those - even after a lot of work my shoulders are pretty tight with my arms behind).
