Monofins in freediving: dolphin technique

The monofin brings the feet together on one surface and gives a dolphin-like movement, which is a favorite among freediving champions.

What distinguishes the monofin

The single stroke of a single fin generates more thrust with the same energy than two separate fins and this conserves energy and oxygen for a longer time.

Correct movement technique

Wave movement
The whole body participates in the movement like a wave starting from the central region and ending with the fin. It is not just the movement of the legs, but the rhythm of the entire body.

Frequency and Amplitude
Slow, deep strokes are better than quick, shallow strokes to save energy.

Suggested training

• Start getting used to wearing a monofin in the pool
• Wave movement exercises on the edge outside the water
• Horizontal swimming in the pool, focusing on rhythm, not speed
