VO2 max predicts all-cause mortality better than most blood markers, and it responds to training at any age. It also plateaus. Most people who train hard and stop improving are doing too much at moderate intensity and too little at the two ends.

The programme measures where your thresholds are, writes the training around them, and measures again eight weeks later. If the number did not move, the plan changes.

Eight weeks at a time

Each block opens with a lab visit: VO2 max on the metabolic cart, lactate at four stages, force plate and grip. Lucía Ferrer writes the next eight weeks from those numbers. Overnight HRV tells us week by week whether you are recovering from it.

Bloods run with every block, so a fall in ferritin or a rise in resting heart rate is seen in weeks, not at the annual check.

Billing

€7,900 a year, billed yearly. Eight lab visits instead of four. If you booked a baseline in the last 60 days, its price is deducted in full.

Every eight weeks

All 120 markers at baseline and month 12. The draws every eight weeks repeat the markers your training depends on.

Best for

For you if

You already train four or more times a week and have stopped improving, or if you are preparing for one event and want it measured.

Not for you if

You are starting from no exercise: the membership will move your numbers further for less.

You want a coach on the floor with you; we write the plan and test it, we do not run your sessions.

Your baseline

Start with a number, not a feeling.

One morning in Madrid. A report you keep. A physician who reads it with you.
