Sexual fitness training

Train for better sex.
Make sex better training.

Train five capacities for longer stamina, more available positions, better overall health and calm confidence under load. Then measure Session Quality and coach the activity itself from the 6.0-MET line toward a genuinely vigorous workout.

Two pillars

Train for it

Build the capacity to last longer, recover faster, use more positions and stay calm under load. Endurance, Control, Mobility, Strength and Mentality are programmed like athletic qualities: blocks, progressions, deload weeks and retests.

Make it count — and make it vigorous

Untrained sexual activity sits on the line: men averaged 6.0 METs and women 5.6.^[2] Which side of the vigorous threshold your session lands on is trainable. We score execution, credit vigorous minutes at 2× in-app, and keep every energy figure honest.

The 6.0 MET threshold

The five capacities

What the PQ measures, what we train

Endurance

Aerobic capacity and vascular function. The single best-evidenced physical input to sexual performance.

Deep Base · 8 weeks

Control

Pelvic floor strength, speed and release. Governs timing, continence and orgasmic control.

The Control Block · 8 weeks

Mobility

Hip, adductor and thoracic range. Determines which positions are available and comfortable.

Open Hips · 6 weeks

Strength

Posterior chain and trunk endurance under load. Holds position without fatigue or compensation.

Two Bodies · 12 weeks

Mentality

Attentional control, arousal regulation and confidence under load. Trains calm presence without adding performance pressure.

The Quiet Mind Block · 6 weeks
