I know where you are coming from. I am a working mum of 4 kiddos. I choose to put myself first when it comes to fitness. The nearest gym is 45 minutes away, so I bought a bench, a dumbell set, , a few tae-bo videos, and I run when it is nice out. I agree with what some have said that it is a conscious decision, when you decide to exercise you will. You really need weights to see good results, cardio alone is not as effective. For what it's worth I am happier making time for myself, which makes my kids happier.
