Not sure where or how but somehow CrossFit got characterized as not having any predetermined rest intervals. Much like many other assumptions in fitness here we just get all crazy, break all the rules ( we didn't know about) and rest for a predetermined time ( 2 Minutes) One of the other things that seems to pop up is a lack of differentiation in the prescribed loads (weights). If you can move the prescribed weight efficiently ( sound mechanics and at a good pace) then go with it. If not then adjust to a weight, reps scheme or movement that enables you to accomplish this. Coaches can help with this. Here are a few examples of scaling up and down the rails.
