Advice from The First Lady of Fitness, Fashion, and Fun and Pittsburgh Certified Personal Trainer (CPT), Independent Beachbody Coach, TurboKick Instructor, and life coach, Jackie Omotalade:

What’s up ya’ll? This is Jackie O.  Today, I am going to explain the difference between fast and slow twitch muscles.

Slow Twitch Muscles – these muscles are perfect for endurance but lack  power.  They are much more efficient at using oxygen to generate fuel for muscle use over an extended period of time.  The are nicknamed the “red” muscles because they are dense with capillaries which help give the muscle a red appearance.  You should work these muscles if you are training for a marathon, long bike race, or other endurance activities.

Fast Twitch Muscles - these muscles are the opposite of slow twitch muscles, offering bursts of energy but only for short periods of time.  Slow twitch muscles use oxygen to  generate energy, while fast twitch muscles use  anaerobic metabolism to create energy.  They serve to provide quick powerful bursts of energy consequently the muscles fatigue quicker than slow twitch muscles.
