My DH is a fitness freak! He cycles to work 20 miles a day, plays squash a couple of times a week, and given more opportunity (we have 2 small DCs so, not a lot of opportunity in the weekends) will happily go running, go club cycling in the weekends. He does triathlons too. Good on him and happy that he is fit and well and also saves commuting money by cycling - although he deos spend an awful lot on his bikes and clothes.
Anyway, he keeps nagging me that I need to do exercise. At the moment I feel fluey and achy. Both DCs had coughs and colds and I have been up with teething DD for weeks now without proper sleep.
His reason for me feeling ill is that....that I don't do enough exercise 
I'm so tired by the end of the day as I'm either at work or with the DCs looking after them. I just want to veg out on the sofa and read a book or watch telly. He gives me the guilt trip every night that I should go out running after the kids have gone to sleep. This is the last thing I feel like doing at that time. He just doesn't get it.
He also perhaps jokingly points out my mummy belly (2 c-sections within 2 yrs and I still have a paunch) and that I am not slim as I used to be. I'm currently 8 stone 2lbs though, even if I am short at 5'2, hardly overweight.
I do like to exercise and have done stuff in the past, including 10K runs. I'm just too tired now. AIBU to ask him to leave me alone??!
