well then she is together with a egocentric douchebag...most couples with kids i know make it work either by taking turns or go together with the kid...im a single dad and have no problems on my week to find time to go to the gym and its easier when you are two. Sure you cant go 2 times a day 6 days per week but its not impossible to stay in shape just because you get kids...and the older the kids get the easier it gets to find time
Quite easy fix just up your dose with 1.5 for every gymhour you have to sacrifice 
Good point and for those that enjoy being parents a little creative use of time can fix a lot.
The one things that chaps my ass is that MANY (not all) parents , feel that having children is somewhat inevitable .
Their default setting of having kids , is what annoys me most.
For example, I love being married and have been more then once to prove it LOL.
BUT, I've advised plenty of younger guys to avoid it.
I see no REQUIREMENT for a happy, productive career man to ever get married and/or have kids.
I've told several younger guys to AVOID getting married , since they obviously enjoy their single lifestyle.
Make no mistake, I think every MAN should have a job, make their own $$ and move out of mom's basement

.
BUT, as long as he takes care of himself, he shouldn't feel guilty or inadequate if he doesn't get married or have kids.
