How Many Sets Do You Really Need to Build Muscle?

Summary

The video script delves into the optimal number of sets for muscle growth, debunking common misconceptions. It reviews research studies, including a 2017 meta-analysis by Brad Schenfeld, which suggest a dose-response relationship between sets and muscle growth, with diminishing returns beyond a certain volume. The script highlights the importance of individual response, proper exercise execution, rest periods, and indirect muscle work in determining the ideal set volume. It emphasizes that while a range of 10 to 20 sets per muscle per week is generally beneficial, the 'sweet spot' varies and can be less for beginners or those struggling with consistency. The video concludes with advice on how to apply this research to one's workout routine and offers free minimalist and optimal workout plans for different needs.

Takeaways

• 💪 The optimal number of sets for muscle growth is likely less than many people are currently doing.
• 📊 A 2017 study by Brad Schenfeld found a dose-response relationship between muscle growth and sets, with 10+ sets per muscle per week showing the most growth.
• 🔄 More recent research suggests there might be an upper limit to the number of sets after which additional volume does not lead to more growth and could hinder it due to recovery issues.
• 🏋️‍♂️ The sweet spot for sets per muscle per week seems to be between 10 to 20, but individual response can vary greatly.
• 👤 Individual response to training volume is highly personalized, with some people responding better to low volumes and others to high volumes.
• 🏋️‍♀️ Exercise execution and maintaining good form while pushing close to failure is crucial, as sloppy sets do not effectively stimulate muscle growth.
• ⏱ The length of rest periods between sets can affect the volume needed for growth, with longer rests potentially allowing for fewer sets.
• 🤔 The way secondary muscles are counted in sets can impact volume recommendations, with some muscles like triceps responding better to higher volumes.
• 🔍 High-intensity training, where one set per exercise is performed to failure, can be effective because it provides a similar stimulus as multiple sets.
• 📉 Even though higher volumes can lead to more growth, the gains from additional sets are marginal, with 5-9 sets giving about 80% of maximum growth.
• 🚀 For beginners and those struggling with consistency, starting with a lower volume and gradually increasing can lead to significant results without overwhelming the body.

Q & A

What is the main topic discussed in the video script?

The main topic discussed in the video script is the optimal number of sets for muscle growth, especially for natural bodybuilders, and the factors that influence this number.

What was the first major analysis on the number of sets affecting muscle growth conducted by Brad Schenfeld in 2017?

The first major analysis conducted by Brad Schenfeld in 2017 compared 1 to 5 sets, 5 to 9 sets, and 10 plus sets per muscle per week, and discovered a dose-response relationship between muscle growth and the number of sets performed.

What did the meta-analysis show about the relationship between the number of sets and muscle growth?

The meta-analysis showed that there was a positive relationship between the number of sets and muscle growth, with 10 plus sets per muscle per week resulting in the most growth.

What was the conclusion of the second meta-analysis comparing lower, moderate, and high volumes of sets per muscle per week?

The second meta-analysis concluded that while moderate and high volumes led to more growth compared to low volumes, there were no significant differences between moderate and high volumes, suggesting an upper limit beyond which more volume does not lead to more growth.

What is the suggested 'sweet spot' for the number of sets per muscle per week based on the analyses?

The suggested 'sweet spot' for the number of sets per muscle per week is somewhere within the range of 10 to 20 sets, although this is still a wide range and the exact number can vary based on individual factors.

What are some factors that an individual needs to consider when determining the optimal number of sets for their muscle growth?

Factors to consider include individual response to training volume, exercise execution, rest periods between sets, how secondary muscles are counted in the total volume, and the specific regions within a muscle being trained.

How did Max UC's experience with training volume and muscle growth differ from the initial findings of the meta-analysis?

Max UC experienced that doing a high volume of sets (30-40 sets per muscle group per week) did not lead to the expected gains, and he saw better growth by reducing the volume to 7 to 12 sets per week per muscle group, training very close to failure while maintaining good form.

What is the significance of maintaining good form and training close to failure in the context of the discussed training volumes?

Maintaining good form and training close to failure ensures that the muscles are adequately stimulated without the need for excessive sets, which can lead to overtraining and hinder recovery and growth.

How do rest periods between sets affect the required volume for muscle growth?

Research suggests that taking shorter rest periods (less than 2 minutes) requires more sets to achieve the same growth as taking longer rest periods, which can influence the optimal volume for an individual.

What is the recommendation for individuals who are not seeing gains despite proper form, nutrition, and rest?

For individuals not seeing gains, the recommendation is to consider increasing the volume slightly, adding about two more weekly sets, especially on lagging muscles, and monitor progress to adjust accordingly.

What resources does the video offer for those seeking customized workout routines based on the discussed research?

The video offers three different weekly workout plans available at buwissi.com/lfw for free, and also directs viewers to builtwithscience.com for a quiz that helps in discovering the best customized program for their needs.
