When it comes to fitness, one of the biggest debates is cardio vs. resistance training. Which one should you prioritize if you want results? As a personal trainer in NYC, I hear this question from clients almost every day. Let’s set the record straight.

Cardio: Great for Health and Calories
Here’s the truth: cardio does burn more calories than resistance training. It’s also essential for heart health, lung capacity, and endurance. A solid cardio routine helps you maintain a calorie deficit and improves overall conditioning.
That’s why every NYC personal trainer will recommend including some cardio in your weekly schedule—whether that’s running, cycling, stair climbing, or HIIT.
But while cardio plays a key role, it isn’t always the star of the show.
Resistance Training: The Star of Muscle Growth
If your goal is to gain muscle and get stronger, resistance training wins. Weightlifting, bodyweight exercises, and strength-focused workouts drive muscle growth, improve metabolism, and build long-term strength.
As a personal trainer in NYC, I’ve seen clients achieve the most dramatic body transformations by focusing on resistance training first, with cardio as a complement rather than the main event.
The Principle of Specificity
At the end of the day, your training should match your goal. This is called the principle of specificity:
Want to get leaner? Cardio will help create a calorie deficit.
Want to build strength and muscle? Resistance training should be your foundation.
Want a balanced fitness routine? Combine both strategically.
Working with an experienced NYC strength coach ensures your training plan matches your goals without wasting time on the wrong focus.
Takeaway: Personal Trainer in NYC Perspective
Both cardio and resistance training matter for overall health. But if your primary goal is muscle growth and strength, resistance training should be your priority.
And if you’re unsure how to balance the two, partnering with a personal trainer in NYC can help you design a personalized program that delivers results while keeping you motivated and consistent.
