Answer:
An activity that requires muscular endurance is one that includes your slow twitch muscles, and one that requires muscular strength is one that involves your fast twitch muscles. An activity that requires slow twitch muscles would be something that involves a lot of intensity for a long amount of time like cycling and running. An activity that requires fast twitch muscles would be something that takes great force for a short amount of time like weight lifting and cross-fit. The difference in long twitch muscles and slow twitch is like the difference between sprints and cross country. You build fast twitch muscles while running sprints and you build slow twitch while running cross country.
