Struggling with overhead lockouts, weak front squats, or inconsistent kipping? The problem might not be your shoulders or hips; it may be your thoracic spine. While many focus on shoulder mobility, this overlooked section of your upper back could be limiting your PRs and setting you up for chronic pain. Discover why addressing issues here might be the key to unlocking your overhead strength, gymnastics potential, and pain-free training.

Can't hit the squat standard in CrossFit without pain? You're not alone. For many CrossFit athletes, limited depth isn't about effort; it's about mobility. Discover the hidden connection between your ankles, hips, and knees that could be the difference between hitting PRs or staying stuck. Learn two simple tests that reveal your mobility profile and targeted fixes that will have you squatting deeper, stronger, and pain-free.

Fats, composed of carbon, hydrogen, and oxygen like carbohydrates but with different structures, provide 9 calories per gram, making them an efficient energy storage system that powers the body during rest and between meals while fulfilling critical functions beyond energy production. Unlike carbohydrates, certain fats are essential nutrients (linoleic acid and alpha-linolenic acid) that the body cannot produce itself, while others contribute to hormone production, cell membrane integrity, and vitamin absorption.

Carbohydrates are molecules made of carbon, hydrogen, and oxygen atoms that serve as the body's primary and preferred source of energy. They're classified by their structure into simple carbohydrates (sugars like glucose and fructose) and complex carbohydrates (starches and fibers), with all digestible carbs ultimately broken down into simple sugars in the body. While they provide quick energy at 4 calories per gram, unlike proteins and fats, there are no "essential" carbohydrates that must be obtained from diet, as your body can produce glucose when needed through other metabolic pathways.
