What Kind of Muscle Fiber Do You Have — Slow Twitch or Fast Twitch?
Slow twitch muscle fibers are more efficient at using oxygen than fast twitch muscle fibers and therefore can extend muscle contractions over a long period of time. They fire more slowly than fast twitch and can go for a long time before they fatigue. These muscle fibers are crucial for endurance activities and sports. Fast twitch muscle fibers do not require oxygen and fire quickly, however they fatigue more quickly. They are crucial for power activities and sports. Most people have a mix of both of these muscle fibers but you probably have one that is dominant. Whatever type you have, just make sure you Funk up your Fibers and hit the weights!
What Should I Do if I Want Lean Muscles Instead of Bulky Muscles?
This is one of my favourite fitness misconceptions because so many people believe there are different types of muscle. You see, all muscle is lean! Just take a look at an anatomy book and you will see what I mean! What makes a muscle appear bulky is the amount of fat underneath the skin surrounding the muscle. Get rid of the fat and ta-da, you have will see your “lean” muscle. Do yourself a favour and do the pinch test. If you can pinch it, it’s fat!
