so vain
I'm gonna hazard a guess here and say that when you train in the gym you may be using weights that are slightly too heavy for you causing you to slacken your form and use excessive swinging to move the weight rather than the target muscle. A lot of people do that and claim they can't grow, but that will be because every training session is cheated. Maybe ego training is one of the culprits. It's not all about heavy weight, it's about forcing your muscle to contract optimally and if that isn't happening, you won't see much muscle growth. Be true to yourself and re-evaluate your training methods.
ding ding ding, we have a winner. This is exactly your problem. As soon as you stop worrying about how much weight youre lifting, and worry more about how you're lifting it...you will start to progress. I lift a lot lighter than a lot of guys in the gym, but when I stand next to them I make them look like shit. I use heavy enough weight to get 10-12 reps with perfect form, slow negatives, lots of squeezing and flexing the muscle. If you want to mix it up a bit, start out with heavy rows, bench, squats, etc for your first exercise of the day. heavy meaning like 8 heavy reps with decent form. Then on your next few exercises use a lighter load and slow your reps down. really focus on the muscle you're targeting, practice good form, and squeeze all the blood into that muscle.
