Your Performance Score

Your Performance Score is 62. A solid base, with clear room to climb.

Most of your answers point to one thing: the body is doing a little less than it used to, and none of it has ever been measured. That is what holds the number back, and it is one of the most workable.

Your reading at a glance
Bottom line
Ten minutes uphill now asks you to slow down, and what your body can do sits a step below where it was five years ago. None of it has been measured, so nothing tells you how much room is left. All three are workable, and the sooner you start, the faster the number moves.
Next move
Three free changes first. Then, if you want to see how much capacity is actually there, a visit to the clinic.
01 · What your score means

A 62, read in plain English.

A score in this range means a solid baseline with clear room to grow. Higher is better, so the goal is simple: move the number up over the next few months. The plan below shows the fastest way.

Your score is built from your answers. These three did the most to hold it back.

Next to five years ago, what your body can do is
You answered"A step back, and I notice it."
Ten minutes walking fast uphill leaves you
You answered"Needing to slow down before the top."
How much of what is going on inside your body has actually been measured?
You answered"Very little. I go by how I feel."

This reading is built only from your fourteen answers. It is a starting point, not a medical diagnosis, and it does not replace a visit with your own doctor.

Three of your answers line up into one pattern.

The work still gets done. What has moved is the ceiling above it. Ten minutes uphill now asks for a slower pace before the top, and next to five years ago what the body can do is a step back you can feel. Neither of those arrived on a particular day, and neither of them shows up on a standard yearly physical, so the only record of the change is your own memory of how it used to feel.

None of this is unusual after 40, and none of it is broken. Think of running the same route every year and finishing a little later each time. No single run is a bad one. The direction only shows up if somebody keeps the times.

Signs the ceiling is holding

  • Ten minutes uphill and you are still talking normally
  • What the body can do is level with five years ago, or better
  • Training moves you forward rather than just holding you steady
  • The numbers behind it have been measured in the last year

Signs it needs work

  • Hills ask you to slow down before the top
  • Five years ago you could do more, and you notice it
  • The same training holds the line instead of gaining ground
  • Nothing underneath has been measured, so there is no way to tell how far
02 · Three free things to lift it
At home · free · start this week

Three changes you can start this Monday.

These come first because they are free, they are what any good plan is built on, and you can start them this week. Each one targets one of the three things holding your score back. They are the first part of the path, and section 04 is the part that measures whether they went far enough.

01

Two strength sessions a week, covering every major muscle group.

Muscle is most of what decides what the body can still do, and adults lose roughly 3 to 8 percent of it per decade after 30 unless training gives the body a reason to keep it. Two sessions a week is the amount the national activity guidelines set for adults. Push, pull, hinge, squat, carry, and add a little weight when it starts to feel easy.
For the ground given back
02

Once a week, take one walk up a hill hard enough that talking gets choppy.

That is the standard test for a hard effort: at that pace you cannot say more than a few words without stopping for breath. Ten minutes uphill is a question about aerobic capacity, and harder efforts lift it faster than steady ones do. Ten to fifteen minutes is plenty to start. Build into it over a few weeks rather than going straight at it, and keep the easier walking too, because the adult floor is 150 minutes a week and the hard walk is on top of it, not instead of it.
For the ten minutes uphill
03

Pick one route and time it every week. Write the number down.

The same hill, the same stairs, the same loop, timed on the same day each week. A change that takes five years to show up cannot be felt, only counted, and a written record is the single best-evidenced way to make a slow one visible. A phone stopwatch and a note is the whole method. It also gives the clinic a real starting line if you go further.
For what has never been measured

Give the hill and the weekly timing two weeks. Give the strength work six, because muscle answers on a slower clock. The check below shows whether they have done their job, or whether measurement is what closes the gap.

After a few weeks of doing these consistently

Signs the changes are working

  • The same hill goes by without slowing down
  • Your weekly time on the same route has come down
  • The weights you started with have started to move up
  • A hard week costs a day or two, not most of the next one

Signs the changes are not enough

  • Same hill, same slow-down, six weeks in
  • The weekly time has not moved
  • Strength has not moved despite consistent training
  • The work is being done and nothing has shifted

If the left column is true, the base is working, and that is the right foundation to build the rest on. If the right column is true, it points to something underneath that only measurement can settle. Either way, the visit is where you find out which of the two you are looking at, and how much capacity is actually there.

03 · A story like yours

How someone with a score of 62 turned it around.

The starting point. A man in his early fifties in Mill Valley, CA came in with almost the same reading: busy job, still training twice a week, but the hill on his usual walk now made him ease off before the top, and what he could lift and carry had drifted down over five years. None of it had ever been measured. His score sat right around the middle.

First, the free steps. He started with the same three changes in section 02: two strength sessions a week, one hard walk up the hill, and the same route timed every Sunday. Six weeks in, the weights had started to move and the time on the route had come down by half a minute.

Then, what the steps could not reach. The hill still asked him to slow down, so he booked a visit. A morning of testing put numbers on what he had been reading by feel: his aerobic capacity came back below the range for his age, a body-composition scan showed less muscle than his weight suggested, and his grip strength sat lower than expected.

The plan that followed. The team kept the free steps, built the training and the eating around what the testing showed rather than around a guess, and re-tested a few months later so he could see the direction of travel. The hill stopped asking for a slow-down, and his score climbed out of the middle.

The free steps did real work on their own. The testing showed the part he could not reach by feel.

04 · If you want to look deeper

How our clinic can help you.

Here is what we do, in plain words, and what each part is for. None start from a quiz.

The longevity diagnostics
The deep baseline JYZEN starts its longevity patients on. Blood, urine and stool panels sit alongside biological age testing, heart-risk profiling, imaging and a brain map, so the picture covers the things a standard yearly physical never looks at.
Why it fits your resultYour reading is about capacity, and capacity is the one thing a set of answers cannot settle. This is the step that replaces the estimate with a measurement.
The Biometrics Lab
A morning of physical measurement in one room: VO2 max, grip strength, body composition, lung function and resting metabolic rate. It measures the two things your answers could only estimate, which are what your engine can actually do and how much muscle you are carrying.
Why it fits your resultTen minutes uphill is a question about aerobic capacity, and a VO2 max test is what answers it. Grip strength and body composition settle the rest of what the body can do.
The 90-Day Metabolic Reset
One of JYZEN's published programs, run over three months by the medical team. Training, eating and recovery are built around what the testing showed, with the numbers re-checked along the way instead of only at the end.
Why it fits your resultGround given back over five years is won back with training and food built on the numbers rather than on a guess, and re-checked while it is happening. That is what this program is.
The health tech floor
The room of recovery technology JYZEN runs on a membership: red light therapy, cryotherapy, Vasper training, and resting and active altitude training. The clinic's own line is that these reward consistency rather than the occasional visit.
Why it fits your resultWhat moves capacity is how much training you can hold, and what decides that is how well you recover between sessions.
None of these start from a quiz. The right next step is a visit. A JYZEN doctor looks at your answers, runs only the testing that makes sense, and decides what, if anything, fits you. Plenty of people leave with just the free plan and nothing to buy.
A note from your doctor

Ethan, this is common, and one of the more workable results we see. Nothing here is broken. A step back can be stepped forward again, and the first part costs nothing. Start with the three changes above this week, because they are the foundation everything else is built on. What they cannot tell you is how much capacity is actually there, and that is what the visit is for, with no pressure either way.

"Bio-optimization means restoring, regenerating, and elevating your health so you can live the life you love and love the life you live."
05 · The next step

The reading is done. The next step is yours.

Start with the three changes in section 02. They cost nothing and begin the work this week. To find out how much capacity is actually there, the next step is a visit. Here is exactly what that is, so there are no surprises.

Book your visit

A tour of the space is free, and guest services confirms the visit fee with you when you book, before anything is scheduled. The tour is free and the fee is confirmed before you book. A clear plan, not a sales pitch.
