text: the best way to lose weight? i am 15, 5 ft 4 in, and 130 pounds.  i want to be 115 pounds and i'll be happy. but im not obsessed about weight though.   i used to be on a swim team so i'm kind of muscular. i have arm muscles and thigh/calf muslces... i know having muscles is nice, but i think mine's a little too much.   i've been excercising for about 40 min each day in the fitness room... but i don't think im losing any weight.   i've stopped swimming, so now there's this thin layer of fat over my abs/muscles... what should i do? i want to tone down my legs... running or elliptical? i want to tone down my arms/get rid of the small flabs... what to do?  please answer the above and don't worry about the diet... i'm good with that already.   thanks!! to lose weight, you need to run more. i would suggest running a total of 45-80 minutes a day. you also need some weight training to increase your metabolism. since you don't wanna be muscular, i would suggest doing high reps of low weight to gain small lean muscles. i would do 20-50 reps of each exercise, and only do a couple exercises with 2 sets of each exercise.here are some exercises i would recommend doing for someone that doesn't want to get bulky but wants to have some strength, be lean, and be fit.   squats (maximum amount you can do without weight for 2 sets)   pushups (maximum amount you can do without weight for 2 sets)  bicep curls (2 sets of 20-25 reps with 8-15lb dumbbells depending on how strong you are)  shoulder press (2 sets of 20-25 reps with 15-20lb dumbbells depending on how strong you are  doing this weight training to speed up the metabolism and running to burn the fat will help you lose weight everywhere you need to lose weight. there is no way to lose weight in just one certain area.   i bet you are losing weight working out 40 minutes a day, but just not at a noticeable rate, so just run more and weight train to make it noticeable.   good luck                        jer
