Andrew Huberman's Cardio Protocol: Zone 2 and the Elliptical
Explore how Huberman incorporates low-intensity Zone 2 elliptical training into his routine and why he prioritizes it for long-term health.
Andrew Huberman's zone 2 cardio protocol calls for 150 to 200 minutes per week of steady effort at 60 to 75 percent of maximum heart rate, split into sessions of at least 30 minutes, with 45 to 60 minutes preferred, performed three to four times per week. The elliptical suits this protocol because it sustains continuous moderate effort without joint impact.
- 60 to 75 Percent Rule: Zone 2 sits at 60 to 75 percent of your max heart rate, hard enough to breathe noticeably but easy enough to hold a full conversation.
- 150 to 200 Minutes Weekly: Huberman recommends 150 to 200 minutes of zone 2 per week in sessions of at least 30 minutes, with 45 to 60 minutes being the preferred length.
- The elliptical eliminates impact entirely, which makes it far easier to hit four sessions a week without the joint stress that interrupts runners.
- A stride that is too short forces a higher cadence and pushes your heart rate above zone 2, so meaningful stride adjustability is not optional on a good training machine.
- Too Hard Is the Mistake: Most people train zone 2 above zone 2 because the correct intensity feels unproductively easy, but the mitochondrial adaptations are intensity-specific and do not transfer from harder efforts.

What Zone 2 Cardio Actually Means
Zone 2 cardio sits at a specific intensity level, not just "moderate" in a vague sense. It refers to exercise performed at roughly 60 to 75 percent of your maximum heart rate, the range where you are working hard enough to breathe noticeably but can still hold a full conversation without gasping.
Physiologically, zone 2 is the upper boundary of aerobic metabolism before your body begins relying heavily on anaerobic pathways. At this intensity, your muscles are burning primarily fat and using oxygen efficiently. Your mitochondria, the structures inside cells responsible for energy production, are being trained to work harder and multiply. Research on endurance athletes and metabolic health consistently shows that sustained zone 2 training improves mitochondrial density and function more effectively than shorter, harder efforts.
The practical test most coaches use is the "talk test." If you can speak in complete sentences but would not want to keep up a long phone call, you are probably in zone 2. If you can sing, you have drifted below it. If you can only manage a few words between breaths, you have gone above it. Heart rate monitors give a more reliable target, but the talk test is a useful real-time check.
Andrew Huberman's Zone 2 Protocol Explained
Andrew Huberman, a neuroscientist at Stanford University, has spoken at length about zone 2 cardio on his podcast, drawing on research from exercise physiologists including Iñigo San Millán, who works with professional cyclists and has studied metabolic health extensively. Huberman frames zone 2 not as a weight-loss tool but as fundamental maintenance for the cardiovascular and metabolic systems, something he describes as a non-negotiable pillar of long-term health.
The protocol Huberman recommends is straightforward: 150 to 200 minutes of zone 2 exercise per week, broken into sessions of at least 30 minutes each, with 45 to 60 minutes being the preferred session length. He emphasizes that sessions shorter than 30 minutes are less effective because the mitochondrial adaptations being targeted take time within each session to kick in fully. The frequency he describes most often is three to four sessions per week.
Huberman also distinguishes between "true zone 2," where you are holding the intensity steady throughout, and the tendency people have to drift above it because maintaining a truly moderate pace for an hour feels almost too easy at first. That discomfort with going slow is one reason many people never spend meaningful time in zone 2 at all. They end up doing zone 3 by default, a range that is physiologically less efficient for the adaptations being sought.
Why the Elliptical Is a Strong Match for Zone 2
One challenge with zone 2 training is that it requires holding a steady, moderate effort for a long time without stopping. Running tends to push people above zone 2 more easily than they expect, and impact accumulates over repeated sessions. The elliptical removes the impact problem entirely while still letting you maintain a smooth, continuous effort that keeps your heart rate in the right range.
The gliding motion on an elliptical produces no ground-strike force on the joints, which matters a lot if you are training four days per week for 45 to 60 minutes per session. Runners doing that volume frequently accumulate enough stress to require recovery days that interrupt consistency. On an elliptical, many people can maintain that frequency with far less joint fatigue, which supports the regularity that zone 2 training depends on.
The HCI PhysioStep MDX, for example, is built specifically around this idea of stress-free continuous effort. Its recumbent design and swivel seat allow users with limited mobility or joint sensitivity to get full cardiovascular work done in a position the body tolerates well. It supports up to 500 lbs and offers 16 levels of electromagnetic resistance, giving a wide enough range to dial in precisely the intensity zone 2 requires without overshooting it.
For people comparing how ellipticals stack up against other cardio equipment for this purpose, the physiological differences between these machines become relevant quickly, especially for anyone managing knee or hip concerns.
Stride Length and Resistance: Dialing In the Right Intensity
Getting zone 2 right on an elliptical is partly a matter of matching your stride length and resistance to your body. A stride that is too short forces a higher cadence to maintain output, which can spike heart rate above the target zone. A stride that feels awkward wastes energy and creates compensations in your gait. The best machines for this kind of training offer meaningful adjustability.
The SportsArt E876 adjusts stride length from 17 to 29 inches electronically, which is a wider range than most users will ever need. That range exists to serve genuinely different bodies, not to look impressive on a spec sheet. A shorter user working at a 19-inch stride and a taller user at 26 inches can both find the cadence and resistance combination that puts them in zone 2 without compensating their mechanics. The E876 also includes a 3-speed fan and fingertip controls, so you can make small adjustments mid-session without interrupting the steady aerobic state you are trying to maintain.
Similarly, the SportsArt E874-13 features electronically adjustable stride length alongside a 13-inch SENZA touchscreen, which gives real-time feedback on pace and heart rate. Watching your heart rate trend during a 45-minute session teaches you more about your actual zone 2 than any pre-workout estimate does.
Self-Powered Ellipticals and Zone 2: A Different Feel
A self-powered elliptical, one that generates resistance from your own motion rather than a motor and electromagnetic brake, changes the relationship between effort and output. On a motorized or electromagnetically braked machine, you can cruise at a fixed resistance while your legs find their rhythm. On a self-powered unit, you control everything, and the resistance curve responds directly to how hard you push.
The SportsArt V886 Verso is a self-powered 3-in-1 cross trainer that combines elliptical, stepper, and cycle movements. Because it is self-powered, there is no motor drawing electricity. The effort required to keep the flywheel moving means your output and your intensity are directly linked in a way that some users find easier to keep honest. You cannot accidentally coast in zone 2 on a self-powered machine the way you might on a motorized one.
The tradeoff is that self-powered machines tend to require slightly more skill to pace consistently. If your cadence drops, resistance increases, and your heart rate can spike above zone 2 before you realize it. For experienced athletes with good body awareness, this is not a problem. For people just learning to work in zone 2, a machine with preset resistance levels and heart rate monitoring may make it easier to hold the target range.
The mechanical differences between front-drive and rear-drive designs also play into this, since the feel underfoot changes significantly between the two and can affect how naturally you fall into a sustainable zone 2 cadence.
The Health Benefits Behind Zone 2 Training
The case for zone 2 training is not just about fitness performance. Research across metabolic health, cardiovascular function, and longevity consistently finds that this intensity range produces adaptations that higher-intensity training does not replicate well. Mitochondrial biogenesis, the creation of new mitochondria in muscle cells, is particularly pronounced at zone 2 intensities. More mitochondria means better fat oxidation, improved glucose regulation, and greater aerobic capacity over time.
Cardiac output, the volume of blood your heart pumps per minute, improves with sustained zone 2 training through adaptations in stroke volume. Your heart becomes more efficient at filling and ejecting blood, which means a lower resting heart rate and a greater reserve capacity during harder efforts. Studies following both recreational and elite athletes have documented these changes, and they appear to occur regardless of fitness starting point.
For metabolic health specifically, zone 2 training has been linked to improvements in insulin sensitivity and lipid profiles. San Millán's work, which Huberman references frequently, suggests that impaired fat oxidation at zone 2 intensities is a useful early marker of metabolic dysfunction, and that training in this zone consistently can restore that capacity. The implication is that zone 2 is not just useful for athletes. It may be one of the most effective interventions for general metabolic health available without a prescription.
A deeper look at what sustained elliptical training does to the body fills in more of this picture, particularly for people approaching this from a health rather than a performance angle.
How to Structure Your Zone 2 Sessions on an Elliptical
The Huberman protocol is clear on volume: 150 to 200 minutes per week, in sessions of at least 30 minutes. In practice, most people find it easiest to build toward this with three sessions of 45 to 50 minutes, which puts you at the higher end of the recommended range without requiring five separate training days.
Set your heart rate target before you start
Calculate 60 to 75% of your estimated max heart rate and write it down. Most ellipticals with integrated displays, like the E876's 16-inch SENZA screen, will show your heart rate in real time if you hold the grip sensors or pair a chest strap.
Spend the first five minutes finding your pace
Start at a low resistance and increase gradually until your heart rate settles into the zone. Do not rush this. Overshooting early and then backing off disrupts the steady aerobic state you are building toward.
Hold the zone for the full session
If your heart rate drifts above the top of zone 2, reduce resistance slightly rather than slowing your cadence dramatically. Small resistance adjustments keep your mechanics consistent and your output steady.
End with a gradual cooldown
Drop resistance for the final three to five minutes and let your heart rate fall naturally. This supports cardiovascular recovery and prevents the dizziness some people experience when stopping an extended aerobic session abruptly.
Choosing an Elliptical With Zone 2 Training in Mind
Not every elliptical serves zone 2 training equally well. The features that matter most are adjustable stride length, reliable heart rate monitoring, smooth resistance adjustment, and enough stability to feel comfortable during a long, steady session. Choppy resistance changes or unstable pedals make it harder to maintain the mental relaxation that long zone 2 sessions actually require.

The right choice depends heavily on what your body tolerates and how you prefer to train. The HCI PhysioStep MDX is the only recumbent option in this group and makes the most sense for anyone with hip, lower back, or balance concerns. Its swivel seat and walk-through design also make getting on and off straightforward, which matters across long training blocks. The SportsArt units are built for users who want a more upright, traditional elliptical experience with premium adjustability and display technology.
If you are earlier in your research and still deciding which category fits your situation, browsing the full range of elliptical machines gives you a clearer picture of how these models sit relative to the broader market. For people who also use a treadmill or are considering one alongside an elliptical for zone 2 work, the treadmill collection is worth a look, since some training plans use both interchangeably across the week.
Common Mistakes That Undermine Zone 2 Training
The most widespread mistake is training too hard. Zone 2 feels almost uncomfortably easy to most people when they first try to hold it honestly. There is a strong impulse to push the resistance up or increase the pace because working at a genuinely conversational intensity does not feel productive. This impulse is worth resisting. The metabolic adaptations zone 2 produces are intensity-specific, and spending that time at zone 3 or zone 4 trains different systems.
Inconsistency across the week is the second major problem. Three sessions one week, zero the next, two the week after that will not produce the cumulative adaptations that a steady 150 to 200 minutes per week builds over months. The elliptical helps here because the low joint stress means most people can maintain their schedule even through minor soreness or fatigue that would sideline a runner. Consistency compounds.
A third issue is session length. Huberman's emphasis on 30 minutes as the floor is grounded in the way mitochondrial signaling builds during a session. Cutting sessions to 20 minutes to fit a busy morning undercuts the biology. If your schedule is tight, two longer sessions and one medium session per week will still outperform five short ones.
How Zone 2 Fits Alongside Other Cardio Modalities
Huberman's protocol does not replace high-intensity training. It sits alongside it. His full cardio framework includes one session per week of higher-intensity work, often structured intervals, and then the three to four zone 2 sessions making up the remainder. The two types of training are not competing; they are complementary. High-intensity work builds peak capacity and VO2 max. Zone 2 builds the aerobic base that makes everything else more efficient.
Some people find that adding a weekly stair-climbing session or a vigorous cycle class fits naturally into this structure as the higher-intensity component, while the elliptical handles the zone 2 volume. How those two machines compare for cardiovascular intensity is useful context if you are building a mixed-modality week.
For people using a recumbent setup like the HCI PhysioStep MDX for zone 2, it is worth knowing that seated elliptical formats can produce equivalent cardiovascular output to upright machines when resistance and duration are matched. The position changes; the physiology does not have to.
Over six to twelve months of consistent zone 2 training, most people notice that the heart rate they once reached at moderate effort now requires noticeably more work to hit. That shift, a lower heart rate at any given output, is one of the clearest signals that the aerobic adaptations are taking hold. It is less dramatic than the progress that comes from intense training, but it runs deeper and tends to persist longer. That durability is partly why Huberman and the researchers he cites treat zone 2 not as a training phase but as a permanent feature of a healthy life.

Frequently asked questions
Is an elliptical actually a good machine for zone 2 cardio, or is it just a compromise for people who cannot run?▾
It is genuinely one of the better options for zone 2 work, not a fallback. The continuous gliding motion keeps your heart rate steady without the spikes that hill variations or pavement changes can cause during running. For sessions of 45 to 60 minutes done three to four times a week, the absence of joint impact also means you can maintain that consistency without needing extra recovery days between sessions.
Is zone 2 cardio on an elliptical safe for people with joint problems or limited mobility?▾
For most people with knee, hip, or lower back sensitivity, an elliptical is one of the safest ways to reach and hold zone 2 intensity. The HCI PhysioStep MDX takes this further with a recumbent design, a swivel seat that rotates 360 degrees for easy entry, and a max user weight of 500 lbs, making it accessible even for those transitioning out of physical therapy or managing significant mobility limitations. The electromagnetic resistance system gives 16 levels of adjustment so you can stay precisely in the 60 to 75 percent of max heart rate range without overshooting.
How much does a quality elliptical for zone 2 training typically cost?▾
The range among the machines PPW carries is fairly wide. The HCI PhysioStep MDX sits at $4,295 and covers the needs of most home users focused on steady aerobic work. The SportsArt E874-13 is priced at $12,995 and adds electronically adjustable stride length and a 13-inch SENZA touchscreen for real-time heart rate feedback. The SportsArt E876 comes in at $14,495 with a 16-inch SENZA display and a 17 to 29-inch stride range. What you are paying for as price increases is primarily adjustability, display quality, and build durability for heavy daily use.
What should I look for when setting up an elliptical specifically for zone 2 sessions?▾
The most important setup factor is stride length, because a stride that does not fit your body forces compensation that makes it harder to hold a natural, steady effort. The SportsArt E876 adjusts from 17 to 29 inches electronically, which covers a genuinely wide range of users. Once stride is set, pair it with a heart rate monitor from the first session so you learn what resistance level and cadence puts you in the 60 to 75 percent max heart rate range before you form habits around the wrong intensity.
What does it cost to run an elliptical over time, beyond the purchase price?▾
Most standard ellipticals have modest ongoing costs, mainly occasional lubrication of the rail system and replacement of consumable parts like pedal straps over years of use. Self-powered models such as the SportsArt V886 Verso ECO-NATURAL Cross Trainer use the motion of the user to generate electricity, which eliminates the power draw entirely. Plug-in machines like the HCI PhysioStep MDX require an electrical outlet to run the display, but the draw is minimal compared to treadmill motors.
How do I maintain an elliptical used for frequent zone 2 sessions?▾
With three to four sessions per week at 45 to 60 minutes each, you are putting real cumulative hours on the machine. Wipe down the rails, stride arms, and contact surfaces after each session to prevent sweat corrosion. Check the drive system and any adjustable stride components every few months for looseness. For electromagnetic resistance machines like the HCI PhysioStep MDX, there are no friction pads to wear down, which reduces the frequency of mechanical maintenance compared to older resistance systems.
How do I know if the stride length on a given elliptical is right for my height?▾
A useful rule of thumb is that a natural walking or jogging stride for most adults falls somewhere between 18 and 24 inches, with taller users needing more range. The SportsArt E876's 17 to 29-inch adjustable stride covers that full spectrum and then some. If your stride feels choppy or you find yourself shortening your natural gait to stay on the footpads, the machine is likely set too short for your body, and you will end up raising your cadence to compensate, which pushes heart rate above zone 2 faster than expected.
What is the most common mistake people make when trying to do zone 2 on an elliptical?▾
Going too hard. Zone 2 at 60 to 75 percent of max heart rate feels almost uncomfortably easy for the first few weeks, and most people drift into a harder zone because steady moderate effort seems unproductive. The result is that they end up in zone 3, which produces less of the mitochondrial adaptation that zone 2 training is specifically targeting. A machine with real-time heart rate display, like the SportsArt E874-13 with its 13-inch SENZA touchscreen, makes it much easier to catch that drift before it becomes a habit.
