trading off [exercise time with a spouse] is a good idea. something else you can do is incorporate exercise into your time with the kids. for me playing catch or street hockey bumping a volleyball or shooting hoops with my kids is a great way to have bonding time playtime and exercise all in one. for younger kids rolling around on the floor dancing to music or piggy back rides can be a workout as well. there's only so much time in a day and i can't always get up at 5:30 am for a "real" workout so adding exercise to my everyday activities helps. it recharges and refreshes me. it's a great way to connect as a family.
how can i fit exercise into my day when i spend so much time with my kids?
