I HATE that excuse. I have 3 kids under 5 and my husband and I make it to the gym every.single.day. including weekends. our gym has a parent/child room that has a large tv and lots of toys and activities for the kids and at least 1 of every type of machine and a full weight lifting set up. its not a massive room but its enough to go and sweat everyday. and on days that the gym is impossible we load up the kids in the jogging strollers and beat feet on the pavement. its not that hard with kids, just more prep work.
