How Many Sets Per Workout? Why More Isn't Always Better

Everything you've been told about doing more sets to build muscle is wrong.

Amy Hudson and Dr. James Fisher discuss the science behind single-set versus multiple-set training and what actually drives real strength and muscle growth. They break down a review paper comparing one set to three sets and share what the data says about hypertrophy and why effort matters more than volume.

Tune in to hear why more isn't always better, how supervision changes outcomes, and how you can build muscle in far less time than you think.

• Dr. Fisher breaks down a review paper comparing one set versus three sets for muscle growth and strength.
• Dr. Fisher covers how effort changes across multiple sets when rest periods are involved. He reveals that sometimes it takes several sets to reach the same fiber recruitment that one high-effort set can achieve. The real driver isn't volume alone, but intensity and muscle fiber stimulation.
• Dr. Fisher reveals that strength increased to virtually the same degree in both the single-set and three-set groups. Whether participants trained one set twice per week or three sets twice per week, the outcome was the same.
• Why muscle size didn't differ between one set and three sets. The study showed equal increases in hypertrophy regardless of volume. One properly executed set to a high degree of effort was just as effective as doing three normal sets.
• How beginners can build muscle with just one set is one of the most encouraging findings. Participants with no previous strength training experience saw measurable gains in just 12 weeks. Even one set per exercise, twice per week, was enough to stimulate growth.
• Dr. Fisher explains that this study aligns with a large body of previous research. One weekly set per session was comparable to six total weekly sets in outcomes. That makes single-set training dramatically more time-efficient.
• Amy explains that when you load muscles effectively and train with proper intensity, one set can deliver the stimulus you're looking for. The key isn't endless volume; It's focused, high-quality effort.
• Dr. Fisher highlights the importance of supervision in the gym. Many strength studies showing impressive gains are conducted under close guidance. Supervised training consistently outperforms unsupervised workouts.
• Why personal training dramatically improves results comes down to accountability and execution. Most people lack the consistency, form, and technical precision required to train effectively alone. A coach removes guesswork and ensures every set counts.
• Amy reveals why personal training solves the motivation problem. Around 80% of people struggle with long-term discipline in the gym. Having structured guidance keeps progress steady without relying on willpower alone.
• Dr. Fisher further explains why having a personal trainer benefits even experienced lifters.
• How to achieve maximum results in minimal time is the core takeaway from this episode. According to Amy, one well-executed set, performed under proper guidance, can stimulate strength and muscle growth effectively.
