After 21 Days: What to Do With the Habit You Just Built

What’s the one area nearly everyone would enjoy toning up?
Men and women of all ages dream of having a leaner core free of stubborn body fat, so they try EVERYTHING.
Sit ups and crunches.
Belly wraps.
Crash diets.
And it just never seems to work!
Why?
Because Average Joes and Jills only see the core as one muscle (the one that looks like a 6 pack on your fittest friends ;)) and don’t train to lean and define the ENTIRE core.
Think of it like making a pizza and only prepping the crust.
It can taste great, but doesn’t count as a fully made pizza because it’s missing the good stuff!
Let’s start by understanding what actually makes up the core.

The core muscles are a group of muscles located in the trunk and pelvis region of the body. These muscles work together to provide stability, support, and movement for the spine, pelvis, and hips. Understanding the anatomy of the core is essential for effective training and injury prevention. Here are the key muscles that make up the core:
Rectus Abdominis: This is the most well-known core muscle and is commonly referred to as the “six-pack” muscle. It runs vertically along the front of the abdomen and is responsible for flexing the spine, such as during crunches.
Obliques: There are two sets of oblique muscles: the external obliques and the internal obliques. The external obliques are located on the sides of the abdomen, running diagonally from the lower ribs to the pelvis. They assist in rotating and bending the trunk. The internal obliques lie underneath the external obliques and work in conjunction with them to rotate and bend the trunk in the opposite direction.
Transverse Abdominis (TVA): This is the deepest abdominal muscle and wraps around the torso horizontally like a corset. It provides stability and compression to the abdomen, acting as a natural weight belt. The TVA is particularly important for core stability and spinal support.
Erector Spinae: These muscles run along the spine and include the iliocostalis, longissimus, and spinalis muscles. They play a crucial role in maintaining posture, extending the spine, and resisting flexion (forward bending).
Multifidus: These small muscles are located along the spine and provide stability by controlling movement between individual vertebrae. They help to support and protect the spine during bending, twisting, and lifting movements.
Quadratus Lumborum: This muscle is located on each side of the lower back, between the pelvis and the lowest rib. It assists in side bending of the trunk and hip hiking.
Pelvic Floor Muscles: These muscles form a hammock-like structure at the base of the pelvis and support the pelvic organs while also contributing to urinary and fecal continence. Strengthening the pelvic floor is important for core stability and overall pelvic health.

Hip Muscles: Muscles such as the gluteus maximus, medius, and minimus, as well as the hip flexors (iliopsoas), play a significant role in core stability and movement. They connect the pelvis to the legs and contribute to pelvic stability and alignment during various movements.
Effective core training involves targeting all of these muscles to ensure balanced strength, stability, and function throughout the trunk and pelvis. Incorporating a variety of exercises that engage the core from different angles and movement patterns can help develop a strong and resilient core. But why does this matter?
Core training is crucial for fitness and fat loss for many reasons, but let’s cover the top 4:
Core training is essential for fitness and fat loss, and incorporating a variety of core exercises into your workout routine can help you achieve a stronger, leaner, and healthier body!
Foundation: Stability and Activation
Build a Base Strength
Integration: Functional Movements
Increasing Difficulty
Mobility and Flexibility: Supporting Core Function
