I've been lifting consistently six days a week got the past 3 years. In the past year and a half I've gained no muscle. And put on fat. My diet is on point. I eat 2000 calories on a cut, with 500 or so cals of cardio, and on a bulk I eat around 4k. I eat 1.5-2 gs of protein and sufficient fat as well. I push myself in the gym and am starting to lose motivation because I'm getting nowhere, it just seems pointless. What could be the problem? I'm 5'9 and 175 currently, and according to measurements I'm 19% bf. Which is ridiculous considering how much i workout and how healthy i eat. I was 6% before i hit my plateau thinking about doing some comps. But now that goal is shot. Someone help tell me what could be wrong, thank you!
