The podcast discusses increasing metabolism through training and muscle building, addressing common misconceptions about metabolism and emphasizing the importance of building muscle and maintaining an active lifestyle. It also explores the impact of supplementation and different types of training on resting metabolic rate. The hosts discuss managing inflammation during training, utilizing activity trackers for better habits, and express gratitude to the listeners.
Resistance training increases resting metabolic rate (RMR) by about 150 calories for up to 72 hours after a session.
Aerobic training can also increase RMR, resulting in an additional 100 calories burned per day.
Both resistance training and aerobic training can increase RMR by an average of 70 to 100 calories per day, independent of muscle growth.

Resistance training and RMR
Resistance training has been shown to increase resting metabolic rate (RMR) in both trained and untrained individuals. Studies have found that RMR can increase by about 150 calories for up to 72 hours after a resistance training session. The increase in RMR is due to the increase in muscle protein synthesis, which is associated with muscle growth. Research also shows that resistance training can elevate RMR between 4.7% and 9.4% in individuals, resulting in an 85 to 169 calorie increase in the two to three days following a workout.
Aerobic training and RMR
Aerobic training also leads to an increase in RMR. Studies have found that after a session of high volume resistance training or an hour of steady-state cardio, RMR can increase by about 100 calories in 24 hours. This suggests that aerobic training can have a similar effect on RMR as resistance training, resulting in an additional 100 calories burned per day.
Meta-analysis results
A recent meta-analysis and systematic review of 22 studies found that both resistance training and aerobic training can increase RMR by an average of 70 to 100 calories per day. These findings suggest that regular training can lead to significant increases in RMR, independent of muscle growth, due to the increased activity and metabolic processes occurring in the body.
Managing inflammation with frequent training
The management of inflammation when training frequently depends on the volume, intensity, and programming of the sessions, as well as individual biofeedback. Spreading out volume and using a higher frequency routine can help minimize inflammation and allow for better recovery between sessions.
Training Volume and Stimulative Sets
The podcast episode discusses the concept of training volume and the importance of focusing on stimulative sets. The hosts mention the concept of 'junk volume,' which refers to additional volume that does not provide a productive stimulus for muscle growth. They reference research suggesting that over 10 sets per session per body part may lead to junk volume, with 12 sets per session being a more optimal threshold. They also discuss the idea of utilizing effective reps, which are sets performed within a certain range of reps in reserve. The hosts emphasize the importance of allocating volume effectively and avoiding excessive fatigue by balancing volume and intensity.
Calorie Expenditure in Resistance Training
The podcast delves into the topic of calorie expenditure during resistance training. The hosts highlight the factors that determine calorie burn during exercise, including total work performed and intensity of effort. They reference a study that provides practical insights into calorie expenditure during resistance training sessions. The study suggests that, on average, men burn approximately three calories per minute, while women burn around 1.7 calories per minute during resistance training. The hosts emphasize the need to view activity trackers and calorie counts from exercise machines with caution, as they may not provide accurate measurements. They encourage individuals to focus on tracking trends and using activity trackers as tools for awareness and accountability.
