Isn't it supposed to get easier?

Mom and I did the Biggest Loser Tuesday night and this morning. If you keep doing it isn't it supposed to get easier? We were tired!!! Hopefully we will be able to get back into the groove of things. Depends on the weather whether or not we walk tonight. We were going to walk last night, but the weather was horrible. Wondering what we are going to do when school starts in 3 weeks. Everyone keep up the good work. Thanks for helping us along and keeping us motivated.
