Essentials: How to Build Strength, Muscle Size & Endurance | Dr. Andy Galpin

Andrew Huberman

Apr 2, 2026

Episode description

In this Huberman Lab Essentials episode, my guest is Dr. Andy Galpin, PhD, Executive Director of the Human Performance Center at Parker University and an expert in building strength and muscle size (hypertrophy). We cover the core principles and protocols for building strength and muscle, including science-based guidance on reps, sets, frequency and rest intervals. We also discuss how breathing and mental focus can enhance training and how post-workout downregulation can speed recovery.

Mindsip insights from this episode:

Achieve hypertrophy with minimum 10 working sets per muscle group weekly

Recent meta-analyses suggest that a minimum of around 10 working sets per muscle group per week is the threshold you need to hit for hypertrophy.

#hypertrophy

#muscle

Rest two to four minutes between sets for strength gains

For true strength development, you must rest two to four minutes between sets to maintain high intensity, which is the primary driver of strength gains.

#exercise

#strength

Avoid soreness as a measure of exercise quality for long-term progress

Soreness is a terrible proxy for exercise quality, and being so sore that you have to skip a future workout is detrimental to your long-term progress.

#exercise

#training

Train for strength daily; allow 72 hours for hypertrophy recovery

You can train for strength every single day since it doesn't cause much muscle damage, but for hypertrophy, you should wait about 72 hours before training the same muscle group to allow for growth.

#hypertrophy

#strength

Prioritize intention over speed for power development

The intention to move a weight as fast as possible is more important for developing power than the actual speed of the movement itself.

#strength

#training

Activate stubborn muscles through eccentric overload techniques

To activate a stubborn muscle you can't feel working, focus only on the lowering (eccentric) portion of an exercise, such as slowly lowering yourself from the top of a pull-up.

#exercise

#muscle

Implement 'three to five' protocol for strength and power training

For strength and power, a simple protocol is to do 3-5 exercises, for 3-5 sets of 3-5 reps, with 3-5 minutes of rest, 3-5 times per week.

#strength

#training

Utilize flexible rep range for effective muscle growth

For muscle growth, any repetition range between 5 and 30 reps per set is equally effective, as long as you take the set to muscular failure.

#hypertrophy

Downregulate with calming breathing after workouts

Spending just 3-5 minutes on calming, exhale-emphasized breathing after a workout signals to your body that it's safe to begin recovery, which can prevent post-workout energy crashes.
