Increase your speed by improving your feel of the water
There are 4 sculling drills included in this video:
Top Scull: This drill helps you feel the water at the setup phase of the stroke. Imagine piling up two mounds of sand in front of you.
Mid Scull: This drill helps you feel the water in the push phase of the stroke. Make sure your elbows are in front of you so you can see them in your peripheral vision. Think angles.
Rear Scull: This drill helps you feel the water at the exit phase of the stroke. Make sure you don’t recover your hand too early by twisting your hand. Keep your hand against the water until your fingertips come out of the water. Imagine rolling a ball behind you.
Sculling on Your Back: Change it up by going on your back. You can go forwards or backward. This is an excellent core exercise too.
For all of these drills, make sure your body position is level with the surface of the water. Use a buoy or kick board between your legs for added buoyancy if needed until you develop the correct form.
