Is it possible to loose fat and gain muscle with weightlifting? I tend to loose muscle when I am on treadmil?

Is weightlifting alone can do the trick? Loosing fat and gaining muscle?|||It's possible but you won't lose much fat if you're just weight lifting; weightlifting=gain muscle, treadmill= lose fat.|||u have to incorporate cardio to lose weight.....u can just weighlight but if there is fat on top of the muscle u wont see it|||A good workout routine is a good start......if your looking for muscle mass you need to lift heavier and at lower reps.....example 3 sets of 6 reps and the 6th rep on all sets should close to failure meaning you have a hard time doing it.........change your routines about every 3 mths so that your muscles don't get use to the routine .....muscle confusion is what makes the muscles grow.....you also need good supplements like creatine (monohydrate creatine has the best track record) drink lots of water with creatine....also a good whey Isolate protein...
