You can sign up and get a FREE 7-day pass to any 24 Hour Fitness. The last time they had this I was able to also get free child care while I was there. I am not sure this time if they are including that or not, but I think if you ask they do!
Go HERE to get 7 days free!
* True Story – I once signed up for a free trial to every gym in my area and had about 2 months of free gym membership. It was nice in the winter when you could not go outside!
