Like many who have the goal to build muscle, you're probably firmly dedicated to your gym sessions are hardly ever miss a beat. You know that you must make sacrifices in your personal life in order to squeeze in this gym time, but that still does not detract you from your goal of seeing a weight gain and being able to build muscle faster than before.
BUT, despite your best efforts, there still may be some mistakes you are committing while you're in the gym.
Consider these top five errors. If you are making even just one of them, you are not going to see the results you could be. 1: Performing too many sets 2: Lack of focus 3: Not recording your workouts
Recording your workouts is HUGE, as is recording your diet in my opinion. It only takes a few minutes but can really help you get to your desired goals much easier by showing you exactly what has worked and what hasn't.
