Need a fitness pal to keep me on track!

I'm trying to do better about logging my food and calories, but I often times forget. I started the year strong (in my opinion) working out 2-4 a week but I fell off last week and didn't workout at all. Plus two kids parties... a lot of cake and pizza... I'm not trying to be pre-baby weight because in my opinion I feel like I would be too small at 23 (108lbs) so I'm aiming for between 115lbs-120lbs. I ran cross country and track in high school so I often times feel discouraged bc now I can't hardly do a sit up or run. Either the tummy lumps are in the way or my knees hold me back (chondromalacia - aka cartilage deteriorating in my knee caps). I'm going off a 1200 calorie intake with 30 minute circuit training workouts 4-5 times a week and I would love a pal to hold me accountable and vice versa! I'll help you with your goal too! I love coaching and motivating, just not myself. lol
