One of the top questions I’m asked as a personal trainer is whether it’s better to lift heavier weights with lower reps or to lift lighter weights with higher reps. The answer is neither. Both methods have their purpose and both can help you meet your fitness goals. Which one you should focus on depends on your particular goals. Are you trying to gain muscle mass? Do you want to lift more than most humans? Do you want to lose weight? Do you want to get jacked? All of these will have an impact on which end of the spectrum you should focus on.
