Run every morning for about 10-15 min, crunches you should do 3 sets of 10 crunches with about a 10 sec rest inbetween (after a week or so, increase it to 3 sets of 12 crunches etc etc) do some jump roping such as 2 minutes of straight jump roping...repeat 6 times
for eating...if you drink soda a lot, then if you stop for just 1 week, you might feel the difference. lots of water instead, drink juice, eat all your green vegetables, even spinach but i hate brussel sprouts everything else is great.
just dont go on any Special K diets lmao
