Goldilocks and the Three Glutes

Your glutes or buttocks are comprised of three muscles: Gluteus Maximus, Gluteus Medius, and Gluteus Minimus. Together with a muscle called the Tensor Fasciae Latae (TFL), they make up the gluteals. One of the best ways I’ve come up with to explain the difference between your three glute muscles is to draw parallels between your […]

What is a kcal?

There is understandably some confusion around the term calorie. A calorie is a very small unit of energy. It is the approximate amount of energy needed to raise the temperature of 1 g of water by 1 degree Celsius. A kilocalorie (kcal) is equal to 1,000 calories. It is the approximate amount of energy needed […]

Nutrients – The Basics

Nutrients are substrates that we need in order for our body to function properly, helping regulate our metabolism and growth. Macronutrienets are nutrients that give us energy. They are our fuel. They are called MACROnutrients because we need them in large quantities — they are the big three! That makes sense, of course, because we […]

Muscle Roles During Movement

Agonist: Any muscle that is the primary mover in a joint motion. Also called Prime Mover. Antagonist: Any muscle that acts against an agonist. Your muscles are paired around your joints in a push-pull relationship, so that if an agonist moves your body one direction, its antagonist moves you the opposite direction. When an agonist […]

Types of Muscle Contractions

There are three important types of muscle contractions: Concentric (muscle shortening): When your muscle exerts more force than is being placed upon it, your muscle is strong enough to shorten and therefore move the associated part of your body. This is also known as flexion and happens when you “successfully” contract your muscle(s). Isometric (neither […]
