Back in the day

Today I've been thinking about how much easier it was to go about things (like going to the gym and actually getting the adequate amount of rest) before kids. I'm really struggling with getting into a structured workout routine. I do workout but its never consistent. Gone are the days when I could workout 2x's a day or at least get in 4 consistent workouts a week and eat clean. I'd love to lose this baby weight and am very frustrated that it's not coming off quite like I'd hoped. I feel like a failure. Does anyone have any motivation, suggestions for balancing life??
