Understanding the Difference Between Slow Twitch and Fast Twitch Muscle Fibers

There's an interesting theory about going back in time, but we're not going to do anything with it. The biggest difference between slow twitch and fast twitch fibers is the strength. Fast twitch fibers are stronger because they are bigger. Even though he didn't study physiology, a smart guy mentioned the difference between small and big muscles, which relates to slow and fast twitch fibers. Slow twitch fibers love lactate, while fast twitch fibers produce a lot of lactate and have nothing to do with it.
