Now, if you want to shed some pounds, cardio i sthe best way to do it. In 3 weeks' time, you should probably do at least 30 mins of mid to high level cardio for 4 - 5 times a week.
More reps on the exercises also helps, but it depends on your body type. I always wind up with more bulk doing that, just because I shock my muscles into growing more.
Nutrition and sleep are often-overllooked factors. Try eating at least 4 times a day, between 3 hour intervals, with no meal being extrememly larger than the other. Foods you can eat during the 3 week period include Boiled chicken breasts, Egg whites, Tuna, Salmon, Fish in general, for proteins and Rice, pasta, oranges for carb intake. make an eating schedule like that for 3 weeks, combine it with solid exercsise and you will not believe your eyes.
