Working out is contagious.
You start up a workout regimen and the next thing you know your husband and kids have the bug too and everyone wants to go to the gym. We got my husband a membership and he's working out now and I've gotta say I love it. I really like working out with him. We end up doing different cardio workouts, but I like to lift with him. And the boy could stand to lose a few pounds too so this is good for him. He says he wants to get back down to his college weight, but I think if he drops 50 lbs he'll be happy and feel so much better. I kinda like him no matter what weight he is, so that's not a factor at all, I just want us to be healthy and be able to keep up with our kids and keep them healthy.
I have a 10 year old son who also likes to workout alongside me as well. He doesn't come with me to the gym often, but when he does I let him do some cardio and then push-ups and pull ups. No lifting for his growing body just yet.
My daughter is nearly 8 and she would love to come to the gym and workout, but that's a no. My little boys just want to come and play in the playroom and watch people play raquetball but I leave them home or with my mother. I love em', but I don't love dealing with them when I'm trying to workout.
Anyway, this is one bug I don't mind spreading through the entire family. It's a GOOD kind of bug!
