Why I Only Lost 2 Pounds

I've been swimming a lot. about a month now and all of it has helped me tone my upper body muscles(I'll work on my lower half soon).Im getting ready for football for next season(i haven't played in 5 years!). My "abs" biceps and triceps shoulders and "pecs" have gotten really well AWESOME! Im excited and ready for track and football. Swimming is great for conditioning for sports. This is why i only lost 2 pounds.
