fat vs muscle?
 

How can I tell the difference between if i gained fat or gained muscle? 2 weeks ago i joined a gym, and have been there every day since then except last saturday. Yet i gained weight. But before i joined the gym, i lost 13 lbs. When i joined, i began to gain. My maximum weight lifting amount has increased though. I also feel skinnier. But i really dont understand.

Im a tad confused, but to give my best possible insight i would recommend perhaps properly calculating youre body fat % and see if it has either increased or decreased and then you can come up with some possible conclusions. You can do this using a fat caliper device, or also at home doing some complex measurements and then caluculating them accordingly based on a body fat calculator available online on certain websites. Hope this helps

You either look more toned (gained muscles), or you look softer (gained fat)...

Buy $2 skinfold calipers on Ebay and you'll know if you are gaining or losing fat or muscle.

You probably gained fat. Unless you're pubescent, most people take a year to gain 5 or at most 10 lbs of muscle in a year.

I gained 4 lbs of muscle the first month I was working out, it came with 4 lbs of fat too
