Anyway to lose fat and not gain much muscle?
Well when you strip away the fat, you will see the muscle beneath that layer. What you want to do is exercise in the very high repetition range. Upwards of 20 to 30 repetitions for each set. A set of at least 4 for each exercise, and at least 3 exercise per muscle group. This will "TONE" the muscles but not make them too much bigger.
I want to lose weight and look more fit but without gaining muscle.
Probably the best thing to do is LOTS of Cardio. Start walking and work your way to running or use the elliptical. Lots of sit ups, and pushups. There are bunch of exercises that can be done with very little weight to tone target areas of the body. You want tone muscle.
I don't have much use for muscle lol I'm not a really sporty girl and Muscles won't really help on the weight side will they?
So this is why you want Tone Muscle. The more tone and dense you can make your muscle, the better they are at helping YOU burn calories. I work out with women who's muscle are not big, and they only show up because the their body fat percentage is very low. They are not "Sporty Girls" either. The more dense lean muscle you have, the easier it is to lose weight. They don't have to be big, but you do need to use them. A change in your diet, and at least 1 hour to more in cardio will see you drop weight quickly.
