In this insightful episode of The Optimal Protein Podcast, I’m joined by Dr. Antonella V. Schwarz, Assistant Professor of Exercise Science, to uncover the powerful connection between strength training, protein intake, and achieving an optimal body composition.
As a former competitive bodybuilder turned researcher, Dr. Schwarz offers a unique perspective on how building muscle — not just losing fat — is the key to transforming your physique, metabolism, and long-term health.
What You’ll Learn in This Episode:
✅ Why muscle, not fat loss, is the real driver of better body composition
✅ The crucial differences between hypertrophy-focused bodybuilding and resistance training for health and strength
✅ How building skeletal muscle mass supports metabolic health, boosts your resting metabolic rate (RMR), and aids in fat loss
✅ What Skeletal Muscle Quality (SMQ) is and why it’s a better predictor of strength than traditional fat-related metrics
✅ Why muscle-related metrics outperform body fat percentage when assessing strength, performance, and overall health
✅ Practical strategies for increasing muscle mass while improving body composition
✅ Why focusing on adding positive habits — like protein and strength training — is far more effective than focusing on removing foods or behaviors
✅ The surprising ways that muscle preservation can slow aging, improve independence, and enhance overall vitality
Key Quotes from Dr. Schwarz:
💬 “Increasing muscle mass is like hedging your bets on life — it’s your best investment for longevity.”
💬 “Instead of focusing on taking away, focus on adding — more protein, more resistance training, more positive habits.”

| 0:00.0 | Welcome to the Optimal Protein Podcast. I'm Vanessa Spina. |
| 0:05.5 | Hello, my friends. Welcome back to the podcast. I'm your host, Vanessa, and I am super pumped for |
| 0:11.6 | today's episode. We are talking with Dr. Antonella Schwartz. She is an assistant professor of |
| 0:17.5 | exercise sciences at Barry University, specializing in exercise, physiology, and a focus on |
| 0:24.1 | human performance. And she is a newly minted PhD. She's been doing a lot of research on skeletal muscle, |
| 0:32.3 | hypertrophy. She actually herself was a bodybuilder at one point, which we start out the episode talking about, |
| 0:39.3 | but she learned a lot about what it means to build the big muscles and then learned the science |
| 0:45.1 | behind it, not just the practical application. |
| 0:47.5 | So in today's episode, we talk a lot about her research focus and studies that she's done, |
| 0:53.6 | which have been on some really innovative |
| 0:55.8 | ways to build muscle more efficiently, and also the importance of skeletal muscle and strength |
| 1:01.9 | as a biomarker, an indicator of longevity and overall metabolic health and wellness. |
| 1:09.1 | So we talked a lot about these topics in the episode |
| 1:12.1 | today and what are some of the ways that we can really focus on building muscle and how the focus |
| 1:19.8 | really should be more on skeletal muscle and less on fat mass. We talk about the best advice that she |
| 1:25.2 | has for beginners or people who are new to building muscle |
| 1:29.2 | and want to really improve their body composition and a lot of the really fascinating research |
| 1:35.7 | that she's been doing. So I had so much fun talking with her on the episode today. I hope that |
| 1:41.5 | you enjoyed it as well. Please share any insights or takeaways that |
| 1:45.2 | you had from the episode and tag us on social media. If you share in your stories, where you |
| 1:50.6 | are tuning in from, or anything that stood out from you for the episode. We will jump right |
| 1:57.1 | into the episode after this quick break. |
