This is a question that definitely has gone through everybody that is lifting weights in the gym. Lifting weights is not everything when it comes to muscle mass growth; there are a lot of small things around it that make the muscle mass increase effectively. Yes, without a proper weight lifting repetition there won’t be any progress at all, but if you stick only to barbell/dumbbell curls and lifts muscles won’t grow an inch further then the repetition allows to. That was your first reason; now let’s look at few others.
Small number of repetitions is not going to help muscle mass. The lower limit of repetitions in a set should be 8, the top 12. Keep the sets in repetitions varying from 8 to 12; If you do less than 8 repetitions, that it is like you haven’t done the exercise; overreacting with more than 12 repetitions will cause bone and joint pain rather than muscle workout. So, try not to overreact with repetitions just to make a point that you are strong.
Don’t focus your workout entirely on machines. Just like I wrote in my previous articles; vary your workout exercises and keep the body surprised with new challenges. Don’t remain too long on one exercise or workout routine.
Nutrition is has a major part in muscle growth. Some say that it is 90 % involved in the entire process. Consider the logics: a basic gym workout takes about 45 minutes to complete, and the rest of the day is left workout-free. During that period if you consume unhealthy nutrition or miss a meal, then muscles won’t have something to work with while blood circulation is at full speed. Bear in mind that the body “exercises” outside the gym too. A healthier configuration of food intake leads to healthier muscles and powerful lifts.
Don’t forget Motivation. It is a key player that will keep you throughout your workout regime. Be motivated and don’t forget that results are coming; be persistent.
