Recovery isn’t just about rest days and protein shakes.
According to leading exercise physiologist Dr. Andy Galpin, most athletes are sabotaging their progress by ignoring critical recovery metrics that could transform their training.
In a recent conversation with neuroscientist Dr. Andrew Huberman, Galpin revealed the science-backed tools that separate elite performers from everyone else—and they’re surprisingly simple.
From grip strength measurements to a game-changing supplement you probably already have in your kitchen, here’s what you need to know.

The Recovery Equation Most Athletes Get Wrong
Galpin breaks down recovery into a deceptively simple formula: total stress load versus recovery capacity.
When stress outpaces recovery, you’re either moving backwards in physical ability or crushing your body’s capacity to adapt. The solution isn’t always doing less—sometimes it’s recovering smarter.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Anytime the total stress load outpaces recovery capacity, you’re either going backwards in your physical ability, or you’re reducing adaptability.
Galpin categorizes this into three buckets: visible stressors (training, workload), hidden stressors (sleep quality, life stress, nutrition gaps), and recovery capacity (how well your body bounces back).
The goal? Maximize stress where you want adaptation, eliminate it everywhere else, and amplify recovery capacity.
Take Your Foot Off The Brake First
Here’s where Galpin’s approach gets interesting.
Most people try to accelerate progress by adding more—more workouts, more supplements, more biohacks. But Galpin uses a driving analogy that reframes everything.
If your foot is on the brake and you push the accelerator, you might go a little bit faster, but number one, you’re wasting a lot of literal gas to go a little bit faster and two, you’re burning your engine.
His strategy: identify performance anchors—the hidden factors dragging you down—and remove them first.
These could be poor sleep quality, chronic inflammation, inadequate hydration, or nutritional deficiencies. Remove two or three anchors, and suddenly your recovery capacity skyrockets without changing your training volume.

Simple Recovery Metrics That Actually Work
Galpin confirms that several accessible recovery markers have legitimate scientific backing—no expensive lab work required.
Morning Grip Strength
Grip strength upon waking serves as a reliable indicator of nervous system recovery. A notable drop from your baseline suggests your body hasn’t fully recovered.
You can measure this with an inexpensive hand dynamometer or even an old-fashioned bathroom scale.
CO2 Tolerance Test
This test, developed by Galpin and performance coach Brian Mackenzie, measures your ability to control breathing mechanics and carbon dioxide regulation.
The protocol is straightforward:
- Take four deep, slow breaths (in through nose, out through nose)
- Take a big inhale
- Perform a maximal controlled exhale through the nose
- Time the duration until lungs are empty (not breath hold)
Galpin’s lab is currently studying the associations between CO2 tolerance and anxiety states, with promising preliminary findings.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
There’s a reason I’m still doing it.
The Finger Tap Test
This overlooked metric taps into upper motor neuron capacity—your central nervous system’s ability to fire repeatedly.
Simply tap your fingers as fast as possible for one minute using a smartphone app. Track your average and watch for significant drops, which indicate CNS fatigue.
Huberman notes this differs from grip strength because it requires repetitive signaling from upper motor neurons rather than a single sustained command.
The Consistency Principle
Regardless of which metrics you choose, Galpin emphasizes one non-negotiable rule: consistency in testing conditions.
Whatever you do, be consistent. So do it under the exact same conditions as you can. That generally means somewhere in the morning cuz that’s when you’re probably going to have the most control, most stability.
Morning testing provides the most stable baseline, similar to heart rate variability measurements.
Why Elite Athletes Track Different Metrics
Galpin’s work with professional and Olympic athletes reveals a personalized approach to recovery tracking.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Some athletes undergo daily blood and urine analysis, full polysomnography (not just wearable sleep trackers), environmental bedroom sensors, and force plate vertical jump testing. Others track something as simple as subjective feel ratings combined with one objective measure.
The key is identifying the two or three performance anchors specific to each individual, then monitoring markers that reflect those systems.
The Problem With Wearable Recovery Devices
Huberman raises a critical concern about popular recovery wearables, citing research from Stanford colleague Dr. Alia Crum.
Her studies demonstrate that false feedback about sleep quality can drive performance in the expected direction—independent of actual sleep quality.
Tell someone they slept poorly (when they didn’t), and cognitive performance drops. Tell them they slept great (when they didn’t), and performance improves.
The concern? Most consumer devices don’t actually track sleep—they track heart rate and breathing patterns, which are merely correlates of sleep depth.

Huberman acknowledges that sleep trackers have raised awareness about sleep importance, similar to how calorie tracking apps reveal actual intake versus perceived intake. But the proprietary algorithms generating “recovery scores” remain unclear to users.
Sodium Bicarbonate: The Kitchen Cabinet Performance Enhancer
Perhaps the most actionable revelation from Galpin involves a supplement you likely already own: baking soda.
Sodium bicarbonate ranks among the most effective, research-backed performance supplements available—and it costs pennies.
The Science Behind Bicarbonate Buffering
Muscle contraction depends on enzymatic function within a specific pH range. During high-intensity exercise, acid buildup (from hydrogen ions) disrupts this range, causing fatigue.
Critically, you’re not running out of fuel or oxygen—you’re experiencing pH-related enzyme dysfunction.
The sensations of fatigue are actually caused by some signal that hey, we’re starting to run out of pH. You’re not out of gas usually. You’re not too low on oxygen. You’re typically going to see signs or feel signals of fatigue way prior to that. Mostly being pH issues.
Sodium bicarbonate makes your blood more alkaline, providing a larger buffer before acid accumulation reaches problematic levels. This delays fatigue progression, allowing more work output.

How To Use Sodium Bicarbonate Properly
For someone attempting mile repeats or other high-intensity interval work, Galpin recommends:
- Dose: Start with ½ teaspoon of baking soda (you can increase later, but starting lower prevents gastric distress)
- Timing: Consume 20-60 minutes pre-workout; 45 minutes is a safe standard
- Preparation: Dissolve in 10 oz of water
- Application: Effective for anaerobic intervals, circuit training, and high-rep resistance work
Galpin warns that sodium bicarbonate is an effective laxative, so proximity to bathroom facilities matters—especially when starting out.
Peak benefits occur at individualized times between 20-90 minutes post-ingestion, so experiment to find your optimal timing.
The Top Performance Supplements That Actually Work
While promising a deeper dive into supplementation in future discussions, Galpin revealed his short list of “ubiquitously effective” supplements.
Beta-Alanine
Similar mechanism to sodium bicarbonate—it converts to carnosine in muscle tissue, acting as an intracellular acid buffer. Cheap, safe, well-studied, and effective at delaying fatigue.
Creatine Monohydrate: The “Michael Jordan” of Supplements
Galpin calls creatine monohydrate the “crown jewel” of supplementation due to its unique combination of safety, efficacy, cost-effectiveness, and multi-domain benefits.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
It is my crown jewel. It is in my opinion without question the Michael Jordan of all supplementation.
Most people associate creatine with muscle performance, but Galpin emphasizes that the majority of research for the past 20 years has been clinical, not sport-related.
Emerging research explores creatine’s effects on:
- Neurological function
- Mental health and depression
- Cognitive performance
- Brain energy metabolism
Huberman, who takes 5g daily primarily for cognitive benefits, notes he perceives noticeable effects—and Galpin confirms there’s sufficient mechanistic research to support this isn’t merely placebo.
There’s enough mechanism now to understand the metabolic needs. People think the metabolism is needed to fuel muscle. But we forget cells, immune cells, red blood cells, nerve cells, astrocytes, brain, all this stuff requires energy.
Practical Takeaways For Everyday Athletes
You don’t need expensive lab testing or elite-level monitoring to optimize recovery. Start with these evidence-based fundamentals:
- Choose 1-2 consistent morning metrics (grip strength, CO2 tolerance, or finger taps)
- Test under identical conditions each morning for accurate baselines
- Identify your performance anchors—what hidden stressors are dragging you down?
- Experiment with sodium bicarbonate before high-intensity sessions
- Consider creatine monohydrate (5g daily) for both physical and cognitive benefits
Recovery isn’t passive rest—it’s an active, measurable process that determines whether your training builds you up or breaks you down.
As Galpin’s work demonstrates, the athletes who progress fastest aren’t always training hardest—they’re recovering smartest.
