Science-Supported Tools to Accelerate Your Fitness Goals

Andrew Huberman, who introduces himself as a professor of neurobiology and ophthalmology at Stanford School of Medicine, frames this episode around tools that can be added to an existing fitness routine to produce meaningful improvement without much extra time. He says most of these tools come from the six-episode series with Dr. Andy Galpin. That series covered a wide range of protocols, from building a fitness routine to recovery, nutrition, supplementation, and training for strength, hypertrophy, endurance and anaerobic capacity.

The selection is personal. The host says he chose protocols from that series that he has started using himself and that he expects listeners to find beneficial and enjoyable. Most of the discussion targets endurance, muscular endurance, anaerobic capacity, recovery, strength and hypertrophy. He also presents the tools as a prompt for listeners to check whether their current routine covers what it needs to, and where they could spend their time and effort more economically. He promises "at least one and as many as 12 tools" that can be added without much extra time or effort. This part of the transcript covers only the first two.

He describes Galpin as a professor of physiology at Cal State Fullerton and an expert in exercise and muscle physiology. He explains that he made this episode because the Galpin series is so broad and deep that people may find it intimidating to decide which protocols to adopt. The host says the tools improved his cardiovascular fitness, strength and hypertrophy training, and recovery. He lists the metrics involved: heart rate variability, resting heart rate, blood pressure and VO2 max, plus performance measures such as jump distance, running speed or distance at a given speed, and the number of good-form repetitions with a given weight. He gives no specific figures for any of these. He also cautions that every performance and health metric "will vary tremendously from person to person," depending on starting point, training history and other aspects of health.

Before the tools, the host summarizes what he calls a core or foundational fitness program, taken from his earlier solo episode on optimal fitness protocols. He limits its scope at the outset. The template is not meant for athletes focused on one aspect of performance. A powerlifter or someone training for a marathon would likely follow a program that differs substantially. It is aimed at the majority of people who want some cardiovascular fitness, practical strength for tasks such as carrying groceries or moving furniture, protection from injury in daily life, and the ability to play recreational sports or go on long hikes without being badly sore the next day. He says the program covers the major areas that "science tells us are important for health span and for lifespan," while also leaving room for performance and aesthetic goals such as fat loss or muscle growth.

The first element is at least 150 minutes, and ideally closer to 200 minutes, of Zone 2 cardio per week, which he says is what the scientific research indicates. He defines Zone 2 practically. It is exercise during which you can hold a conversation without getting winded, but where pushing a little harder would make it hard to finish your sentences. It can generally be done while breathing only through the nose, and talking during it is fine.

Beyond Zone 2, he says an ideal program would include two to four separate cardiovascular sessions and two to four resistance training sessions. He acknowledges that most people lack the time or discipline to reach the upper end of all three. The version he describes, which he says he has essentially followed for 30 years or more, therefore uses three of each:

One long, slow endurance session per week, such as a long jog or hike. One shorter cardiovascular session of about 25 to 30 minutes at a higher pace, heart rate and breathing rate. One very short high-intensity interval session, such as sprints, which can be done on a rower or a bike instead of running. A leg-focused resistance session. A torso session covering chest, shoulders and back together, plus some neck training. A session for smaller body parts such as biceps, triceps and calves, for muscular balance, injury avoidance and posture.

He notes that resistance training can use body weight, free weights or machines. He stresses that the template is optional and meant as a reference for people to evaluate and possibly change their own routines: "that program is not a mandate." He also mentions a free downloadable PDF, linked in the show notes, with example sessions, exercises, and the reasoning behind repetition ranges and rest periods.

The first tool is to "mesh your Zone 2 cardio with your daily activities." The host repeats the conversation test and says fitness trackers can measure Zone 2 precisely. He gives tracker-free checks as well: talk with a partner while jogging, walking or hiking, talk aloud to yourself if no one is around, or confirm that you can breathe only through your nose while your heart rate and breathing are raised. He says any of these will show "more or less" whether you are in Zone 2.

He restates the 150 to 200 weekly minutes as a minimum supported by scientific data for cardiovascular and cerebrovascular health, among other benefits. Then he describes his own routine. Usually on Sundays he jogs slowly for 60 to 90 minutes, or hikes for one to four hours, outdoors when he can because he values nature, sunlight and fresh air. He admits this single session does not always get him to the weekly minimum.

The host recounts that Galpin's response to this reframed the issue. According to his account, Galpin said scheduling Zone 2 as a long run or as treadmill or bike sessions is fine, but:

he doesn't actually think of Zone 2 cardio as exercise at all.

The host says he was briefly deflated, then reassured by the explanation. In his account, Galpin said Zone 2 is critical to health and that "Zone 2 cardio does not impede, and in fact can enhance our other aspects of fitness," including strength, hypertrophy, speed work and other cardiovascular training. Galpin's recommended approach was to walk more, especially at a brisk pace, and to move more overall during the week. The host's examples include carrying groceries, running around with children, walking meetings with a coworker, and pacing or going outside while on work calls.

The host explains why this mattered to him. He says he is very busy and cannot see a way to schedule more cardio without cutting into sleep or time with family and friends, both of which he calls extremely important to mental and physical health. He raises the target to a firm minimum of 200 minutes per week. He suggests that someone who moves enough during the day may not need to count the minutes at all. Note that this suggestion rests on his own experience and Galpin's view as he recounts it, not on separate data presented here.
