In brief
What you will learn
- •Fit and stiffness shape the movement task.
- •Body line comes before harder propulsion.
- •Turns must preserve direction and equipment security.
Choose equipment from the task
Monofin and bifins create different movement patterns and demands. Foot-pocket fit, blade stiffness, ankle mobility, venue rules and the learner goal matter more than appearance or the fastest equipment available.
Establish the line before increasing resistance
Hands, head, trunk and legs create the direction the fins will amplify. Moderate short repetitions make it easier to notice hip breaks, excessive knee action or a head position that redirects the body.
Build propulsion that remains recoverable
Increase distance or resistance only while the learner can stop, surface and remove equipment without distress. Numbness, rubbing, cramp or a shifting foot pocket ends the repeat.
Carry the body line through the wall
Set the push-off direction before applying force, hold a controlled streamline and begin the first propulsion cycle without collapsing at the hips.
- Use a visible depth marker.
- Compare several moderate exits.
- Recheck fit after turns.
