Tried and tried again...failed & here I am again... TRYING fo Realz this time!

Okay, so I'm hitting 33 very soon, have 3 kiddos, 13, 11 & 1 year old. I'm prior military & was in sports. Tired of this extra goodness hanging on me! I weight 166 lbs at 5' 3", goal to be 120 - 125 lbs (toned)..(like I used to be) by THIS SUMMER. I just need someone to help hold me accountable. The military was great cause I had others to compete against. Now kinda doing it on my own. Any volunteers to help hold me accountable?
