Finning techniques are the skills and methods used by swimmers and underwater divers to propel themselves through the water and to maneuver when wearing swimfins. There are several styles used for propulsion, some of which are more suited to particular swimfin configurations.
A diver should be able to move through the water using their fins as the exclusive means of propulsion to increase efficiency and minimize the impact to the environment. The use of arms and hands provide very little to the diver’s ability to push through the water and are more likely to cause overexertion.

So, which scuba finning techniques should we focus on and when are we actually going to use them?

FROG KICK
Technical divers commonly use the frog kick as their primary finning technique of choice since the force of this stroke is directed toward the rear of the diver rather than downward to avoid silt. In addition, the frog kick propels the diver through the water easily, while requiring the least amount of work.To start the frog kick, bend both knees at a 90° angle outward and upward, while spreading the lower legs apart horizontally allowing your fins to be parallel to the bottom. The next step is to straighten out the legs while thrusting the fins rearward in an arc shape then clapping them together.

Divers commonly use a variation of this finning technique, called the “modified frog kick” which can be completed by reducing the size of the arc needed to propel the diver forward and kicking mainly from the knees and ankles
