Membership Tour

Everything inside, before you decide.

Measured sexual activity averages 6.0 METs for men and 5.6 for women — the exact line between moderate and vigorous exercise. Which side yours lands on is trainable. Membership is the training.

The guided tour

Eight slides, start to finish

Step through the whole platform in order — what it is, how you're measured, what you train with, who you train alongside and what it costs. Use the arrows, the dots or your keyboard.

Step 1 of 8

1 · The idea

Train for better sex. Make sex better training.

Sex sits right on the line between moderate and vigorous exercise. Which side yours lands on is trainable — and training it is the whole product.

  • Five capacities: Endurance, Control, Mobility, Strength, Mentality
  • Programs that build them, session scoring that proves it
  • No public feed, ever — your training stays yours

Your Performance Quotient

Six minutes, five capacities, one number out of 100 — the unweighted mean of Endurance, Control, Mobility, Strength and Mentality. Your lowest subscore is your limiter, and your limiter names the block you train next. Re-test every four weeks.

Session Quality

Score the session, then raise it

SQ scores execution out of 100: vigorous-zone share 45%, average intensity 25%, duration 15%, muscular recruitment variety 15%. PQ moves slowly. SQ can improve tonight.

Raise Your SQ

  • Interval structure — deliberate tempo surges and recovery. The largest lever on vigorous-zone share.
  • Position sequencing — ordering positions so different muscle groups take the load.
  • Active-partner rotation — both partners working, raising the average for both.
  • Duration extension — added minutes at a held intensity.

Honest numbers: 101 ± 52 kcal for men and 69.1 ± 25.6 for women per session, mean 24.7 minutes (Frappier et al., PLoS ONE 2013). It was never 300 calories. The way to raise it is to train the intensity.

Devices and health apps

Your wearable does the measuring

Live heart rate

Session mode reads heart rate live, tracks time in the vigorous zone and scores SQ as you go.

Apple Health

Sessions write to Apple Health with true elapsed minutes. The 2× credit stays in your iSexercise ledger — inflating a health record would be dishonest.

Encrypted sync

Session data is encrypted on your device before it syncs. We store ciphertext and hold no key, so we cannot read it.
