Welcome to 3FC!!! This is a wonderful place full of tons of encouragement and motivation!
As a sahm to 4 kids--two of them being 3 yr old twins--I can totally relate to feeling like you don't have time to devote to a workout routine. I used to feel exactly the same way! However,
JamieJo took the words right out of my mouth--
You have to make time for it! I told myself a million times I couldn't do it, the kids got up too early, or they were up all night, hubby got home too late but ya know what? I'm now exercising 6 days a week--and
the kids still get up too early or stay up all night and hubby still gets home at the same time (or later).
What really helped me was to find a group to be held accountable to. There's lots of great groups here--the one that clicked for me was the Monthly Challege Group over on Chicks Up for a Challenge. I've been with them for every challenge since May and have found more motivation and inspiration than I thought possible!
So peruse the board, check and see which groups look like a good match and go for it! We'd love to have you on the Monthly Challenges btw!
Welcome once again and good luck!
