Ready for a different kinda summer

Hello,
My name is Melissa. I'm 29 with 2 babies. I have a 3 year old and a 2 year old. Last summer was pretty rough. I didn't have the energy or the confidence to get out and enjoy the summer. Although I did take my babies to the beach and various outings, I feel like I didn't really get to experience it or enjoy it. I more so dreaded the heat because of the extra weight I've been carrying ( I usually love the heat) and I didn't get in the water at the beach. This summer I want to join my babies in the fun. I want the energy to keep up with them. I want the confidence to join them in our swimsuits. I just want to be happy with what I see in the mirror. I want my old body back. I'm ready.
