this is a question at wich i cannot say a response because i don't know how strong si the average of gymnast.
so for some of the regular strength movements like push up, hs pushup, ring push up, hanging leg lift, wide grip pull up and muscle up....what is a great number of reps so that you can say "i am enough strong to pass to another movements or add weigth?"
sometimes during my training i usually do some exercise (out of WOD) but i don't know if my max reps are in the average or under the average, in this way i don't know when is the moment to increase the difficult...
for example in the hanging leg lift i can do 22-23 reps at the bar, with traigth legs touching the bar without lift the ass to make the movement more easy. makes sense continue to increase the reps or is better increase the weigth?!
