Locomotor movements
transport the body from one place to another, such as walking or running.
Non-locomotor movements
done in one stationary spot without traveling, such as bending or stretching.
Manipulative movements
a person uses their hands, feet, or other body parts to give force to, receive force from, or control an object.
Core muscle group
efers to the collection of muscles surrounding the abdomen, lower back, pelvis, and hips that work together to stabilize the spine, maintain balance, and support body movement.
Rectus abdominis
the “six-pack” muscles at the front of the abdomen.
Transverse abdominis
the deepest abdominal muscle; helps stabilize the spine.
Internal and external obliques
located on the sides of the abdomen; help with twisting and bending.
Erector spinae
muscles along the spine that help keep the back upright.
Multifidus
small muscles along the spine that provide spinal stability.
Diaphragm
the main breathing muscle, which also contributes to core stability.
Pelvic floor muscles
support the pelvis and help stabilize the trunk.
Gluteal muscles
especially the gluteus maximus and medius; they help stabilize the pelvis and hips.
Bracing
Tightens all the core muscles around the trunk.
Creates a firm, stable torso.
Useful for lifting, sports, and exercises requiring stability.
Feels like preparing the stomach for a gentle punch.
Hollowing
Pulls the belly button inward toward the spine.
Focuses mainly on activating the deep abdominal muscles.
Often used for improving awareness and control of the deep core.
Feels like “drawing the stomach in.”
Exercise progression
the process of making an exercise more challenging as a person becomes stronger or more skilled. It helps improve strength, endurance, and performance.
Exercise regression
the process of making an exercise easier when the current version is too difficult or when someone is still learning proper technique.
Physical fitness
is the ability of a person to perform daily activities, exercise, and physical tasks efficiently without excessive fatigue, while still having enough energy for other activities.
Cardiovascular Endurance
This is the ability of the heart, lungs, and blood vessels to provide oxygen to the muscles during continuous physical activity. Activities such as running, swimming, cycling, and brisk walking can improve it.
Muscular Strength
is the ability of a muscle or muscle group to produce force. For example, lifting or carrying a heavy object requires this.
Muscular Endurance
the ability of muscles to perform repeated movements or maintain a contraction for an extended period. Exercises such as planks, push-ups, and sit-ups can help develop it.
Flexibility
refers to the ability of the muscles and joints to move through an appropriate range of motion. Good ___ can make movements easier and may help reduce the risk of injury.
Body Composition
refers to the proportion of fat, muscle, bone, and other tissues that make up the body. Maintaining a healthy this is influenced by physical activity, nutrition, genetics, and lifestyle.
Progression
means gradually making an exercise more challenging as a person becomes stronger or more skilled.
Regression
means modifying an exercise to make it easier when the original movement is too difficult or when a person is still learning proper technique.
Musculoskeletal fitness
refers to the ability of the muscles, bones, joints, and connective tissues to support movement and perform physical activities effectively.
Bracing
is the action of tightening the muscles around the entire trunk—including the abdominal muscles, sides, and lower back—while keeping the spine stable.
Hollowing
is the action of drawing the abdomen inward toward the spine to activate the deeper abdominal muscles, particularly the transverse abdominis.
Bracing Steps
Stand or lie in a comfortable position.
Take a normal breath.
Tighten your abdominal muscles as if preparing to receive a gentle punch to the stomach.
Keep the tension while continuing to breathe normally.
Avoid sucking your stomach inward excessively.
Hollowing steps
Lie on your back or sit comfortably.
Relax your stomach.
Gently pull your belly button inward toward your spine.
Hold the contraction while breathing normally.
Avoid holding your breath or strongly squeezing the entire body.
Toe Touch
stretches the hamstrings and lower back.
Arm Across Chest Stretch
stretches the shoulders and upper back.
Quadriceps Stretch
stretches the muscles at the front of the thigh.
Butterfly Stretch
stretches the inner thighs and hips.
Cat-Cow Stretch
promotes movement and flexibility of the spine.
Side Stretch
stretches the muscles along the sides of the torso.
