No, heavier gloves do not make you hit harder. In fact, they can actually have the opposite effect. Heavier gloves, while providing more protection to your hands, tend to limit the range of motion in your wrists and arms, making it difficult to generate power or speed in your punches. Additionally, the added weight of heavier gloves can increase fatigue and reduce agility due to the extra strain on your muscles. Therefore, using a light glove is generally recommended for boxing training and sparring as it will help improve hand speed and overall technique.
