Hello. I am 13 years old and 5"10 and weigh 170 lbs. I recently changed my lifestyle 2 and started biking 7 miles a day to the fitness center where I work out. I started eating way more healthy. I ride my bike to school and back and run for 9 minutes in gym. If i keep this up, how much weight could i lose before august 2012, and is it possible that i could get a six pack? I plan to stick to this routine because i really want to change my life. Thanks. Feel free to ask anything else.
