Your metabolism is about MORE than how many calories you can burn during a workout. 👇
Your Total Daily Energy Expenditure (TDEE) come from 4 primary components:
1️⃣ BMR (Basal Metabolic Rate (60-70%): This is where the largest portion of calories we burn comes from everyday. It’s the energy your body uses to keep you alive, maintain muscle mass, brain function, and organs working!
2️⃣ NEAT (Non-Exercise Activity Thermogenesis): All the movement outside of intentional exercise. Walking,taking the stairs, cleaning the house, and playing with the kids.
3️⃣ TEF (Thermic Effect of Food): The energy your body uses to digest, absorb, and process the food you eat.
4️⃣ EAT (Exercise Activity Thermogenesis): Intentional Exercise. Strength training, running, cycling, swimming, rucking, etc.
SO WHY DOES BUILDING MUSCLE MATTER?
Muscle is metabolically active tissue, meaning it requires energy to maintain. But its importance goes well beyond the calories it burns at rest.
Skeletal muscle is one of the primary places your body takes up and store glucose. Maintaining and developing muscle through resistance training supports insulin sensitivity, glucose regulation, strength, and physical function as we age.
Research supports this:

📚 Resistance training and resting metabolic rate

The takeaway: We are not just training to burn calories. We’re training to build a stronger, healthier body that serves us for decades.
