Exercise isn't the goal. Fitness is. We measure yours and build a program around it.
VO2 max is one of the strongest predictors of how long you'll live. Most people have never had it measured. We test it with a metabolic cart, screen your movement quality and hanging endurance, and build a coached training program around the results.
How this protocol works
This isn't just testing. It's a coached cycle designed to get you where you want to be.
What we measure
VO2 max
How long you'll live, in one number
Maximum oxygen uptake, measured with a metabolic cart and a submaximal ramp protocol. Not estimated from a watch. This is one of the strongest predictors of all-cause mortality, and most people have never had it tested.
Dead hang
Shoulder health and endurance under load
How long you can hang from a bar with straight arms. Tests shoulder stability, grip endurance, and lat engagement over time. One of the simplest markers of upper-body functional capacity, and a daily practice we prescribe to every member.
Standing vertical jump
Power fades faster than strength
A measure of explosive power output. Power declines faster than strength as you age, and it's the thing that keeps you from falling. Most fitness programs ignore it entirely.
Movement Quality Score
Where your body is restricted
A 5-position functional screen: full squat hold, overhead reach, single-leg stance, floor get-up, and passive bar hang. Each failed position generates a daily practice prescription to fix it.
Zone 2 benchmark
Monthly progress tracking
Same workload, same modality, every month. This tracks your aerobic improvement over time without requiring another VO2 max test. Your team reviews trends and adjusts your program.
What’s different after this protocol
You know exactly where your body stands. Not “I feel like I’m in decent shape.” Actual numbers: your VO2 max percentile for your age, your grip strength against population norms, how much power you generate, and whether your body moves the way it should.
You’ve spent a full training cycle on a program built around those numbers. Regular coaching calls, movement video review, and a plan that adjusts when life gets in the way.
At the end of the cycle, we retest everything. Same protocols, same equipment. The numbers either went up or they didn’t. If they moved, you know the program is working. If they didn’t, we figure out why and rebuild for the next cycle.
What this protocol delivers
- Your VO2 max measured by metabolic cart, with your percentile ranking for age and sex
- Dead hang time and vertical jump power benchmarked against population norms
- A Movement Quality Score (0-5) with daily practice prescriptions for any failed positions
- A training program built for your tier, equipment access, and schedule
- Coached training with regular check-ins and movement video review
- Zone 2 benchmark sessions tracking aerobic improvement over time
- A full retest showing what changed
- Integration with every other protocol: your glucose data, sleep patterns, and body composition all inform your program
”Do you exercise?” is not a fitness assessment
At your annual physical, your doctor asks if you exercise. You say yes. They check a box. That’s it.
But “I exercise” covers an enormous range. It says nothing about your cardiovascular fitness, your strength, your power, or whether your body moves well enough to keep doing the things you care about. Those numbers matter more than most people realize. Low VO2 max carries a mortality risk comparable to smoking. Low grip strength predicts disability and death independent of anything else on your chart.
The problem: nobody measures these numbers outside of a research lab. Your trainer tracks your PRs. Your Apple Watch estimates your VO2 max (and gets it wrong more often than not). But nobody has put you on a metabolic cart, tested your grip with a calibrated dynamometer, screened your movement quality, and built a program around the results.
You wouldn’t manage your cholesterol without a blood test. Why would you manage your fitness without measuring it?
The plan: coached training cycles
Assessment, program, coached training, retest. Your team runs you through the same battery at the start and end of each cycle, so the numbers either move or they don’t. Members who keep progressing transition to Alumni with periodic retests and self-directed training.
See how a cycle runs
Full assessment. Your team runs the full battery. Movement quality screen across 5 positions. Grip strength. Vertical jump. VO2 max via metabolic cart. Based on results, you’re assigned a tier: Foundation, Development, or Performance. You also set Decade Goals together, which are the specific physical tasks you want to be able to perform at 75, 85, and beyond.
Program delivered. Your team delivers a customized training program selected from a library of templates (tiers crossed with equipment profiles: full gym, minimal, or hybrid). The program covers Zone 2 cardio targets, resistance training, power work, and daily non-negotiables like squat sits, hangs, and walking.
Coached training. You film movement sessions; your team reviews the video and responds. Wearable data is monitored for resting heart rate trends and HRV drops. When something comes up, pain, low energy, no time, each scenario has a specific adjustment built into the program. No guessing.
Milestone check. Your team reviews proxy metrics: heart rate, HRV, and adherence data. If you’re improving, you continue. If you’re not improving despite good adherence, they run a systematic review looking at sleep, nutrition, hormones, and iron. If adherence is the issue, they simplify the program.
Full retest. Your team runs the same battery: VO2 max, grip, vertical jump, movement screen. Results are compared to your baseline. The next cycle is planned. Members who meet graduation criteria after sustained progress transition to Alumni status with periodic retests and self-directed training.
This isn’t a program with a finish line. It’s a physical practice you build over years.
We match the program to where you are
Three tiers. Foundation (Tier 1) is for members building a base. Development (Tier 2) is for members who train but without much structure. Performance (Tier 3) is for members already fit and training consistently. Same testing, same coaching cadence, same retest across all three. What changes is where the program starts and how fast it progresses.
See what each tier looks like
Foundation (Tier 1). You’re not currently active, or you’ve been away from structured training for a while. A baseline training schedule plus daily non-negotiables: a squat sit, a dead hang, a daily walk. The goal is building a base without burning out.
Development (Tier 2). You exercise regularly but haven’t been training with structure or measurement. Zone 2 cardio, resistance training, and power work designed around your specific test results and weak points.
Performance (Tier 3). You’re already fit and training consistently. The program focuses on pushing VO2 max higher, maintaining or improving power output, and addressing the movement restrictions that show up under load. More advanced programming, more volume.
Common questions
Is this protocol right for me?
A few patterns fit. You exercise regularly but have no idea whether what you're doing is actually working. You've never had your VO2 max or grip strength tested and want to know where you stand relative to your age group, not an estimate from a wearable. You're over 40 and starting to notice things you used to do without thinking are getting harder, and you want a plan to reverse that trend rather than accept it. You have a trainer but nobody is measuring outcomes, integrating your health data, or retesting to verify that the program is producing results.
How does this work?
Full assessment, a training program built around the results, coached training with ongoing check-ins, and a retest to see whether the numbers moved. Members who meet graduation criteria after sustained progress transition to Alumni with periodic retests.
Do I need to complete other protocols first?
No. Physical Capacity is Protocol's most popular offering and can be your first protocol after The Foundation. It also serves as the integration point for exercise prescriptions from other protocols.
I already have a trainer. Is this different?
Yes. Your trainer programs your workouts. This protocol measures your baseline capacity (VO2 max, grip strength, power, movement quality), sets evidence-based targets, integrates your health data from other protocols (glucose, sleep, hormones, body composition), and retests to verify improvement. Many members keep their trainer and use Protocol for the diagnostic and programming layer.
What if I'm not currently exercising much?
That's Tier 1, Foundation. A baseline training schedule plus daily non-negotiables: a squat sit, a dead hang, and a daily walk. The program meets you where you are.
What comes after this protocol?
Physical Capacity is the integration point for every other protocol. Your CGM data from Metabolic Health shows which training types improve your glucose response. Sleep Health data informs training timing and recovery capacity. DEXA results from Muscle and Body Composition inform protein targets and resistance training volume. Exercise prescriptions from other protocols are unified here into one program, so you're never juggling conflicting advice.
What does this cost?
Included in Protocol membership: $695/mo, or $7,500/yr prepaid (save $840). The Foundation Assessment is the on-ramp: $1,500 standalone, included with annual membership.
From the Protocol blog
VO2 max is the number that predicts how long you'll live. Have you ever had it measured?
Not estimated by a watch. Measured by a metabolic cart, interpreted by an exercise physiologist, and used to build a training program designed for the physical tasks you want to perform at 75, 85, and beyond.
