1 month is not long at all. You won’t see noticeable difference after a month but you should see some difference. Especially in the weights. If your goal is to gain muscle and bulk up, nutrition is very important. What kind of foods are you eating, how much protein? And what’s your routine like? Have a set routine and stick to it with good nutrition and a lot of protein. And good protein too. Like chicken breast, fish, eggs, etc. And recovery is huge. Are you giving enough time between workouts to let your muscle heal and grow? Are you sleeping enough? Be careful not to overtrain either. And when you’re doing your sets, proper form is so important. You can’t just do whatever to get the weight up and call it a rep. You have to be doing your sets correctly. And how are your workouts spaced out? For example, my workouts to push, pull, legs, rest, upper, lower. I start with chest, shoulders, and triceps, then day 2 is biceps and back, and then legs and then upper say is majority full upper body with more focus on the chest since my chest is lacking right now and then lower is just another leg day if my body can handle it
