Backsliding

I'm pretty frustrated. Before I started training for the tri, I regularly weighed in around 157 and was trying to get down closer to 155. I slowly added a few pounds while training for the tri. It makes sense, I cut back on strength training without adding in enough extra cardio to compensate for that missing calorie burn, plus I was eating more carbs so my body could handle the cardio. Now, however, I've slowly crept up to 167, and I am NOT okay with that. I'm now 12 pounds away from my goal instead of 2! Not cool, body, not cool. I know a lot of it also is that the whole month of June has been crazy. We spent a week in Florida where the only exercise I did was running one morning the whole time we were there, then we were home for four days before heading to CA for a week. I was slightly more active there but still nothing to write home about. I haven't had a good routine which I know is a huge part of the problem. I'm planning on getting back on track Monday...start using Lose It again, have regular, PLANNED workouts at the gym (planning what I'm going to do ahead of time really helps me get a good workout in), and I think I'll plan a low carb week or two for myself. I'm not happy with how I look, with how my clothes fit, how I look in a swimsuit. I'm not doing another tri until late September, and the only other events I have over the summer are an occasional 5K, so this is the perfect time to get back into the habit of regular strength training and get rid of this extra 12 pounds I managed to find. BTW, I managed to maintain my weight on both trips which I thought was awesome. I stayed at 163 the whole time, but then somehow once we got home from CA I put on an extra four pounds that just haven't dropped off. Ugh!!
