Far as I know, there's no way to get stronger and lose fat all at once. It may look like you're losing fat if you're gaining muscle, but this is because you're not eating in caloric defacit, and you're gaining mass..When you gain this mass, it is going to stretch out the fat and displace it..it's not going to go away, it's just going to be thinned out, understand? That's why if you take a bodyfat test at week 1, and it reads 20%, and if you're dieting for mass gain, then 5 weeks or so later, you're going to look like you lost fat, and the test will read a lower fat %, but this is because you added more muscle, so of course your going to have a greater body area now, meaning you're going to have more of an area for the fat to collect, and have a less bodyfat%
