Hand paddles can help a swim coach discover hidden technical flaws in a number of ways. So continue to progressively load volume and intensity to properly stress acceleration(s) specific to creating and sustaining maximal force throughout a stroke cycle. In order to find the flaws, simply be aware of any small pauses that are followed by 'excitable' movements.
The catch in swimming is not a moment in time. Rather its a series of dynamic movements to initiate the propulsive phase of all swimming strokes and we wanted to accentuate that feeling with our Mimic Swim Paddles. And give you a better understanding of your progress with the stroke visualizations in the KineFusion Swimming app.
