Ok, so I'm 15 years old, 6 feet 150 Pounds. I've been working out for about a 9 months, just started off with some 15 pound dumbbells and I've done ab exercises. This winter I really got serious about the abs but when golf season started (i play golf for my high school) I really got off track. So now I'm ready to get back to work. I have some abs but its just not good enough for me. I have about 1 month until I go to the beach on vacation, and i'm willing to devote myself, so what are the best ways for me to get good abs in that amount of time? By the way I think my body fat % is about 11-12%.
