Does running sprints or long distance train the hamstrings?
Both will train the hamstring, but sprints will make them far stronger and more explosive as the sprinting motion involves bigger strides, more range of movement, and a lot of stress on the hamstrings. This is why people who don’t sprint need to work their way into sprinting to avoid getting a hamstring injury. Unlike most people, sprinters have hamstrings that are stronger than quads.
