Your body, measured—
not estimated.
Box is a physiological testing lab. We measure your VO₂ max, lactate thresholds, resting metabolism and body composition, then hand you the numbers your training and nutrition should actually be built on.
Every test: consultation, lab measurement, report & debrief. Led by Jack Braniff — MSc, SENr & CISSN.
Six tests. One question each.

Pick the combination that answers your question. Every price includes consultation, lab measurement, a full report and a 1:1 debrief.
InBody body composition
A 15-second scan plus a short consultation — muscle, fat and water, segment by segment.
RMR + InBody
Your resting metabolic rate by indirect calorimetry, plus an InBody scan — calorie and macro targets built on real numbers.
VO2max only
Treadmill or bike ramp test — your aerobic ceiling and personal heart-rate and pace training zones.
VO2max + Lactate
The VO2max ramp plus blood lactate sampling — your zones pinned to the decimal. Our most popular test.
VO2max + RMR
Your aerobic ceiling and training zones, plus your resting calorie burn — the two numbers behind training and nutrition.
VO2max + Lactate + RMR
The complete picture — aerobic ceiling, exact lactate thresholds and resting metabolic rate, in one visit.

A nutritionist and a lab, under one roof.
Most people either see a coach who guesses at their numbers, or a lab that hands them a spreadsheet and no plan. Box does both — gold-standard measurement, then a registered performance nutritionist who turns it into training zones, calorie targets and a fuelling strategy you can actually follow.
Testing is led by Jack Braniff — MSc Sport & Exercise Nutrition, SENr & CISSN registered, UKAD anti-doping advisor and author of Fuelling The Functional Athlete.
Consultation
Fifteen minutes on your history, training and goals, so the test and debrief are built around you.
Measurement
Breath-by-breath metabolic carts, blood lactate sampling and InBody analysis — the same methods used in sports-science labs.
The report
A clear, designed report of your numbers — thresholds, zones, substrate use, race predictions — yours to keep.
The debrief
You sit down with Jack and leave knowing exactly what each number means and what to do next.
Monochrome—until it’s about you.
The brand is black and white. Your data isn’t. Every report speaks in the same six-colour zone system, so once you’ve read one, you can read them all.
