Dear Iron: You’ve Got My Heart Pumping!

For decades, the recommendation for heart health was simple: Do more cardio. Get your steps in. Walk, jog, run, spin to your heart’s delight. And yes - daily movement absolutely improves health. But it’s not the only piece that matters.

More recently, research has made something clear: building a stronger body helps build a stronger heart.

So how does pumping iron keep the heart pumping?

Here’s what strength training does for cardiac health:

1. Lowers Blood Pressure

Regular resistance training has been shown to reduce both systolic and diastolic blood pressure. In many cases, the reduction is comparable to moderate-intensity aerobic exercise. Less pressure means less strain on the heart and blood vessels.

2. Improves Cholesterol

Strength training can increase HDL (“good” cholesterol) and reduce LDL and triglycerides. Healthier lipid profiles are associated with lower risk of atherosclerosis and cardiovascular disease.

3. Improves Blood Sugar Control

Skeletal muscle is one of the primary sites for glucose storage. The more muscle mass you have, the more efficiently your body can regulate blood sugar. Improved insulin sensitivity lowers the risk of Type 2 diabetes (a major cardiovascular risk factor).

4. Reduces Visceral Fat

Not all fat is created equal. Visceral fat (the fat stored around your organs) is strongly linked to heart disease. Resistance training has been shown to reduce visceral fat, even without dramatic weight loss.

5. Lowers Overall Cardiovascular Risk

Large population studies show that people who regularly strength train have a significantly lower risk of cardiovascular events and all-cause mortality. The greatest benefit appears when resistance training is combined with aerobic exercise. The odds are in your favour when you do both.

Is Strength Training Safe for the Heart?

This is a valid question, especially for those with existing cardiovascular concerns. Strength training with poor form, breathing, and intensity can have the opposite effect. 

At Evolved, our approach is built with safety in mind:

Supervised

Proper breathing, controlled tempo, and appropriate intensity reduce unnecessary cardiovascular strain.

When you hold your breath during exertion (called the Valsalva maneuver), blood pressure can temporarily rise. That’s why our coaches are diligent about cueing proper breathing during every set.

Low Impact

Controlled resistance challenges muscles and depletes glucose stores without pounding joints or causing chaotic heart rate spikes.

Short Duration

Brief, high-effort sessions can improve cardiovascular and metabolic markers efficiently without prolonged stress on the system.

We’re training to adapt and thrive, not stress and strain. 

The heart is arguably the most important muscle in your body. Let’s train it with care.
