It's swimsuit season, and I want to gain a six-pack,along with defined legs.I'm 13, I have 14 days of school left, and right now School & My Friends are my main concern.I get home by 3:30,and usually i'm busy all night.Are there any tips on quick ab workouts,other than the regular sit-ups? uh,I agree,but I really don't want to get up early than 4:30,which is when I usually wake up.Shower,hair,make-up,homework...
