Develop powerful hip rotation
Successful freestyle is applying a rotating force (your hips) to a fixed object (your leading hand at the catch). Let your leading hand glide forward in the water (little finger down), reset your hips vertical, then bend your wrist slightly and turn your hips quickly into the catch.
Think less about your arms and more about your hips. Where your hips go, you go.
Always be aware what your hips are doing
