Depois Da Biomecânica, Nunca Mais Fiz Isso

In this segment, seasoned strength coach Rodrigo Barros reflects on a long‑standing mistake he made while performing the lateral raise (elevação lateral). He explains how beginners are typically taught to focus solely on the movement pattern—lifting the arms laterally with dumbbells—without considering which muscle (the lateral deltoid) is actually being targeted and how that muscle should move. Barros introduces the concept of cinesiologia, the study of muscle actions, and argues that training should be organized around the intended muscle rather than the superficial motion. He then describes the common “roubo” (cheating or swinging) technique, where trainees use momentum to lift heavier loads. While sometimes employed as an advanced method, Barros asserts that when used unintentionally it is a biomechanical error: it reduces the stimulus on the target muscle and overloads unintended structures, increasing injury risk. Drawing on over 25 years of experience and biomechanical study, he warns that such practices compromise training effectiveness and safety.
