The amount of reputations one should do in a workout

One of the most important questions that people ask, especially if their beginners, is how many reps should I use and what weights best would suit me? It all starts off plain and simply as, in what ways do you want your body to look, feel, and benefit from these workouts. If you use a lighter weight and you go more reps(12-15), you will increase your fat burning stages, but decrease with amount of muscle, yet leaving you with strong but lean muscle fibers. If you use heavier weights and with the fact of less reps( 8-10), you will increase your muscle growth but will not have as much fat burning stages to you workouts.
