Go to the Gym for an Hour Every Day… So Why Is My Heart at Risk?


Dear Reader,

Sarah* sat across from me, arms crossed, frustration written all over her face.

“Dr. Loden, I work out every day. I spend an hour on the treadmill or elliptical, I hit my step goals, and my Apple Watch says my heart rate zones are great. But my recent labs showed insulin resistance, and now you’re telling me my heart isn’t as healthy as I thought?”

I could tell she was frustrated.

She wasn’t running marathons. She wasn’t overtraining.

She was doing exactly what most people are told to do for their heart—spending at least 30 on cardio most days of the week.

And yet, something wasn’t working.

Why Standard Cardio Isn’t Enough for Heart Health

For decades, we’ve been told that “cardio = heart health.”

Doctors and fitness experts alike recommend 30-60 minutes of steady cardio as the gold standard for preventing heart disease.

Sarah had been following that advice perfectly—yet her body was showing early signs of metabolic dysfunction.

Why?

🚨 Most cardio workouts don’t improve metabolic flexibility. Many people doing daily cardio are still burning mostly sugar for fuel, instead of fat. That leads to insulin resistance, which increases heart disease risk.

🚨 Cardio alone doesn’t preserve muscle mass. After age 30, we naturally lose muscle if we’re not actively maintaining it. Less muscle means a slower metabolism, more insulin resistance, and a weaker heart.

🚨 The wrong intensity can increase stress instead of build resilience. Many people spend too much time in the gray zone—too intense to be truly restorative, but not intense enough to build strength.

Sarah raised an eyebrow. “So you’re telling me that my cardio isn’t bad, but it’s not doing what I think it is?”

I nodded. “Exactly. If we really want to improve your heart health, we need to focus on two specific types of training.”

Training a Strong Heart

1️⃣ Zone 2 Training: The Heart’s Secret Weapon


💙 Moderate-intensity, steady movement at 60-80% of your max heart rate—like walking at a brisk pace or cycling at a low resistance

💙 You should be able to speak in complete sentences but be slightly short of breath.

💙 Teaches your body to burn fat for fuel instead of relying on sugar, improving insulin sensitivity.

💙 Builds mitochondrial efficiency, which lowers inflammation and strengthens cardiovascular function.


2️⃣ Strength Training: The Missing Piece for Heart Health


💪 Builds and preserves muscle mass, which is directly linked to better metabolic and cardiovascular health.


💪 Improves insulin sensitivity, lowering the risk of heart disease and type 2 diabetes.


💪 Increases overall endurance and resilience, making your heart work more efficiently.

Sarah frowned. “I’ve always avoided strength training because I thought cardio was enough for my heart.”

I smiled. “You’re not alone. Most people focus on burning calories instead of training their heart in the best way possible.”

At Vitality Medical & Wellness Consulting, we focus on exercise that protects your heart for the long run.

✔️ We assess your metabolic health to determine the best exercise prescription for your unique needs.
✔️ We incorporate Zone 2 training and strength training to maximize mitochondrial function, insulin sensitivity, and heart resilience.

Sarah sighed, then smiled. “Okay, I get it now. I don’t need to work out harder—I need to work out smarter.”

I nodded. “Exactly. And the good news? We can start making those changes today.”

Are You Training for Longevity or Just for Calories?

Most people think hitting the treadmill or elliptical every day is enough for their heart. But real heart health comes from training your body to use energy better, not just burning calories.
