Anyway, she has been so angry about this subject that she won't even answer questions about her daily exercise - for example I ask "how far did you guys run today?" or " what body part did you work on with your weight training?" or "where did you guys ride today and how far?" and her answer has always been (over the past 8 months) "Do not ask me any questions about my training - you are not involved and it isn't any of your business...".
I would advise you not to ask any questions regarding her training/exercise b/c it does sounds like you are investigating to a WAW. It would be best not to go near this area. Remember to keep your conversations sparce and let her be the one to start them.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
