Ive been researching a lot and noticed that when you are trying to gain muscle mass and build up your muscles you should eat more calories. The problem is i dont want to gain weight by eating more calories because im worried that my strength training and aerobic plan wont burn up all the calories i take in..leading to a weight gain in fat. I am a 17yrold female, 145lbs, and i have a pudgy stomach which i would like to be more toned so i dont feel uncomfortable wearing fitted shirts. I recently started doing a few strength training w/ dumbells bicep curls, lunges, etc total of 8 excersises3 reps of 15 each. I do tht every other day for a time to rest the muscle groups. on the days i rest i do vigorous aerobic workouts on an elliptical trainer.45min high performance-it says i burn a total of800 cals but im not sure if thts accurate just want a toned body dont want to be hugecan some1 gimme advice how to gain muscle but notfat by eatingall of these calories in day. 3500=1lb gota b careful
