Question about weight and muscle

[Pavao911]

I'm 5 foot 6 ish 145, nothing special with the amount if muscle on me obviously, but the fighters on the lightweight division in the ufc are 155 and RIPPED. How is this possible with only 10 more pounds than me and muscle weighing more than fat?

I'm 5'6" 140 on a heavy day haha.. I could be wrong but I think alot of the guys that look BIG have extremely light bone structures. Some adults are just heavier than others. And 10 lbs of MUSCLE is quite a lot man.

^ this. Take 10 pounds of ground beef. Now think about that being added on to your body in muscle. Thing is they also cut to make this weight so their weight before the cut is heavier. Less fat and losing water weight can bring you lower. Water makes up a lot of our body mass.
