Proper form is essential for exercise efficacy as it maximizes the benefits of workouts while minimizing the risk of injury. Correct posture and alignment ensure that muscles are engaged appropriately, which enhances strength, endurance, and overall performance. When exercises are performed with poor form, individuals may overcompensate and place undue stress on joints and surrounding tissues. Learning and practicing correct techniques can lead to better results and more efficient workouts. By prioritizing proper form, individuals can achieve their fitness goals while protecting their bodies from potential harm.
