I guess I did offend you lol. You've made good progress in 4 years. congrats. But as a rule of thumb, if you enjoy working out, chances are you aren't working out correctly. If you've never thrown up from doing 1 set of curls to temporary muscle failure... you aren't taking full advantage of your time in the gym. Anyone that disagrees just doesn't know what they're talking about and has been lost in the skewed, outdated idea's of "muscle and fitness" articles for far too long. Keep in mind, I'm not just some asshole on here, I'm actually trying to throw you a few tips. But do what you want with what i've said. Regardless, you've made good progress. good luck.
