From everything I have read and know .. belly fat is all about stress, and intake. If will help, I think you may be doing too much by 4 days of cross fit. Just a thought.... you may want to use a HR monitor and see where you are .. You may be an editor sitting on your butt a lot, but I am a dental technician, I sit for long periods too, however, I am still moving and have a stressful job. As an editor, you're having to think for others, just like I have to think for the dentists, that's what we get paid for, but still it is stressful.. tummy fat is cortisol induced.. stress is very big part of that. Spend more time playing with your kids and do cross fit 2-3x a week, maybe just once and do 2-3 strength training instead. shorter, more intense and then relax more.
