Why this matters

The metric that predicts how long, and how well, you live.

6×
A 10-year Mayo Clinic study of nearly 4,000 adults found that those with the lowest muscle power were six times more likely to die than those with the highest.

Power
Functional capability

Strength means you can lift the suitcase. Power means you can hoist it into the overhead bin. Power is what lets you stand up quickly, climb stairs, and catch yourself before you fall — and it declines faster than strength.

DexaFit + Proteus

Your DEXA shows what you have.
Proteus shows whether you can use it.

DexaFit Measures

Capacity

Do you have it?

  • Lean muscle mass By region
  • Bone density Fracture risk
  • Body composition Fat distribution
  • Visceral fat Metabolic risk
Proteus Measures

Capability

Can you use it?

  • Functional power Watts, multi-planar
  • Reaction speed Acceleration
  • Bilateral balance Left vs. right
  • Power Age Vs. chronological age

Together, they tell you where you stand.

Your position in the matrix determines your most important next step.

Your report

You'll walk out knowing exactly where you stand.

Five data points that tell a complete story about your functional power — and what to do next.

i

Your Power Age

How your power output compares to others of your age and sex — your functional age, not your birthday.

ii

Your Profile

Push, pull, rotate, and lateral force — four planes of movement, benchmarked against normative data.

iii

Your Biggest Opportunity

The one movement pattern with the most room to improve — your highest-leverage training focus.

iv

Your Strongest Area

The movement you're best at relative to your peers. A baseline to protect and build on.

v

What To Do Next

Specific training recommendations — or a full 8-week program built from your exact results.

The Proteus dataset

There is no comparable dataset in the fitness industry.

Your results are compared against Proteus's proprietary normative database — over a billion movement data points, from tens of thousands of individuals aged 7 to 101, factored by age, sex, and movement type.

Common questions

Quick answers before you book.

Who is this assessment for?
Adults focused on healthspan, function, and getting more out of their training. You don't need to be an athlete. Most of our clients are in their 30s, 40s, 50s, and 60s — people who care about how they move and want better data than scale weight or body fat percentage.
How long does the assessment take?
About 15 minutes including setup, instruction, and the four movements. Easy to add on to your existing DEXA visit.
Is it physically demanding?
No. The Proteus uses light, controlled resistance and you perform short movements — push, pull, rotate, lateral lunge. There's no max-effort lifting or jumping. Most clients are surprised how easy the movements feel while still producing precise data.
Do I need a DEXA scan first?
Not required, but the data is most useful when paired with your DEXA results — that's how we determine your full profile across the four quadrants. Most clients book both in the same visit.
How often should I retest?
Every 8 to 12 weeks if you're actively training. Power responds faster than muscle mass to focused training, so retesting on this cadence gives you a clear signal of whether what you're doing is working.
Is the 8-week program required?
No. The assessment is valuable on its own — many clients take the report to their existing trainer or use it to guide their own programming. The 8-week program is for clients who want a turnkey plan built from their specific results.
