How to Build Strength, Muscle Size & Endurance ft. Dr. Andy Galpin

8 science-backed protocols for building a body that actually performs — Dr. Andy Galpin's complete system for strength, hypertrophy, and conditioning.

Preview · 3 of 8 tactics

"Most people train randomly and hope. You can't hope your way into a stronger body. Every adaptation you want has a protocol. Pick your goal, follow the protocol, and your body will do the math."

Dr. Andy Galpin is a professor of kinesiology at Cal State Fullerton and one of the most respected exercise scientists working with professional athletes — UFC champions, MLB players, and Olympic athletes. In this episode, he and Huberman translate decades of research into a clear, protocol-based system for building the body you want. No supplements. No gimmicks. Just the specific, non-negotiable inputs required for strength, hypertrophy, power, and endurance. If you've been training for years without measurable progress, this episode is likely the reason — you've been mixing goals and confusing your body's adaptation response.

TACTIC 01

Train for One Adaptation at a Time

Galpin's foundational point: your body can adapt to almost any stimulus, but it can't adapt well to multiple contradictory stimuli at the same time. Strength training, hypertrophy, endurance, and power each require different protocols. People who try to 'get strong while getting lean while improving cardio' usually get mediocre at all three. Elite athletes periodize — they focus on one adaptation for 6-12 weeks, then move to the next. 'The body is literal. It will give you what you ask for. The problem is people ask for everything at once.'

THE PLAY

Pick the one adaptation you want most for the next 12 weeks. Strength: max weight lifted. Hypertrophy: muscle size. Power: explosive force. Endurance: cardiovascular capacity. Every session in that block should prioritize that goal. You can maintain the others at 60-70% effort, but don't split your focus equally. Measurable progress in one adaptation is more valuable than marginal progress in four.

TACTIC 02

The Strength Protocol: Heavy, Low Reps, Long Rest

Galpin's protocol for pure strength is precise. Load: 85-95% of your one-rep max. Reps: 3-5 per set. Sets: 3-5. Rest: 3-5 minutes between sets. The load-rep combination is non-negotiable — lighter weights with more reps produce hypertrophy, not strength. The long rest is where most people fail. They rush back to the bar in 60 seconds, don't recover, and their next set is suboptimal. 'Rest is not downtime. It's when the nervous system rebuilds its capacity for maximal output.'

THE PLAY

For 6-8 weeks, pick 3-4 compound lifts (squat, deadlift, bench, overhead press, pull-up). Train each twice per week. Every set: 3-5 reps at 85-90% of your one-rep max. Rest 3-5 full minutes between sets. Track your loads weekly. If you're not adding weight every 1-2 weeks in the early phase, your recovery or protocol is broken. Strength is the most measurable adaptation — use the numbers.

TACTIC 03

The Hypertrophy Protocol: More Volume, Less Rest

Building muscle size requires a different protocol entirely. Load: 65-80% of one-rep max. Reps: 8-15 per set. Sets: 4-6 per exercise. Rest: 60-90 seconds. The key variable is total volume — sets times reps times weight — and Galpin says most people don't do nearly enough. Effective hypertrophy requires 10-20 hard sets per muscle group per week. The reps should be challenging; the last 2-3 reps of each set should feel difficult. 'Hypertrophy is a volume problem. If you're not getting bigger, the answer is almost always: do more sets.'

THE PLAY

For each muscle group you want to grow: plan 10-20 hard sets per week, distributed across 2-3 sessions. Reps in the 8-15 range. Rest 60-90 seconds. Every set should end with 2-3 reps left in the tank at most — if the last rep is easy, the weight is wrong. Measure muscle growth by circumference, not the scale. Track monthly, not weekly.
