There is a great number of people whose objective is to lose weight to improve the way their body looks. Because muscles are fat burning machines, by increasing your lean mass (body weight minus body fat) you will be able to lose body fat faster and more efficiently. This is one of the reasons why muscular hypertrophy (muscle growth) is one of the most desired results. Nonetheless, the majority of people enter a gym without any idea of where to start, no control over the loads, and a lot of misconception on what is the most effective and safe way to go. Regardless of what your goal is (to lose weight, to gain muscle or both), entrust a qualified PT to save time and energy spent on ineffective training. Working with a professional and responsible training method is essential to minimize the chances of injury, to employ efficient body mechanics, and to maximize the available strength and energy of the movements.
