It's harder once we become moms esp when we work full time outside the
home.
I would either workout during my lunch hour or do an aerobic dvd at home
Walking the dog is great for the dog but isn't usually considered aerobic
exercise to burn for at or lose weight.
I would continue to walk the dog & enjoy those walks.
Go to the gym on the weekends. That's 2 days a week right there. Then
try to fit in 2-3 more days/week.
Realize your limitations & that you may not be able to workout every day
and/or get to the gym.
You can try the kids club at the gym again but don't push it. It's an age
thing. I didn't want to have my child go there when he was a baby so I
would go when my husband was home then that didn't work for awhile.
Wait and try again later.
In the meantime, do what you can when you can.
Walk any chance you get. (Try for 30 mins minimum)
I liked getting an exercise DVD of my choice for those times when going
to the gym wasn't feasible.
If you can steal 20 mins at diff chunks of time during the day (lunch hour,
before you pick up your daughter, in the morning before you leave for
work & hubby is home, after she goes to bed, after dinner etc. then do it)
The motivation will be how you feel after awhile.
You'll start eating better, making better choices, your clothes will fit better etc.
Pick up one Fitness magazine. It can be a inspirational.
In the mornings, try doing 15 pushups, planks for the count of 60 seconds, tricep dips.
Have a goal. (For example, lose 10 pounds or "I want to buy a new black
dress in one size smaller).
Eat healthy. Make healthier food choices.
