Episode #370: Dr. Sohee Carpenter on High-Intensity Circuits vs. Traditional Lifting, New Research, and Coaching Her Mom

Author: Barbell Medicine October 14, 2025 Duration: 57:10

In this special episode of the Barbell Medicine Podcast, Dr. Jordan Feigenbaum welcomes back friend of the show, Dr. Sohee Carpenter, PhD, to share her latest insights following the completion of her PhD in Sports Science from the Auckland University of Technology. 

We dive deep into the research from her recently published paper in the European Journal of Sports Science, exploring a highly relevant question for strength athletes and the general population alike: How do high-intensity circuit training (HICT) and traditional strength training compare?

Key Topics Covered:


  • PhD Research Deep Dive: Dr. Carpenter breaks down her study, which compared HICT against traditional resistance training in trained women over an eight-week period. The groups performed the same exercises, sets, and reps, and pushed to similar proximity to failure, with the key difference being the rest periods.
  • The Results: Find out the surprising, yet encouraging, findings regarding strength gains and muscle growth between the two popular training modalities. The results suggest that for many, personal preference, time constraints, and gym logistics should be the deciding factors for training style—as long as you push close to technical failure. 
  • Circuit Training & Time Efficiency: We discuss why circuit training is a popular option for time efficiency—her study's circuit group completed their sessions in approximately 50-55 minutes, compared to 70-75 minutes for the traditional group. 
  • Coaching Loved Ones: Dr. Carpenter shares her personal experience and advice on training her 64-year-old mother. We cover how she successfully addressed barriers like accountability and self-efficacy, starting with short, positive sessions (initially only 20 minutes) and gradually progressing to longer, more challenging workouts.
