What is a good routine to get a six pack by summer?
I go to a girls family's lake house every summer, I really like her, and used to have a six pack. But I lost it, I'm not fat, in fact I grow muscle pretty quickly I just have been lazy for a while. I'm 14, and I'm looking for something I could do once a day that would give me a six pack by the middle of summer. US. It is 2.8.13
