Paul Lefiti

Paul Lefiti has spent over 20 years studying tennis serve biomechanics and is widely regarded as one of the game's most detailed serve analysts. He works with players across all levels and is known for helping advanced servers increase their speed dramatically—often taking players from 110–115 mph into the 130 mph range through improved mechanics and sequencing. His approach combines deep biomechanical understanding with clear coaching cues, covering everything from grip and stance to advanced sequencing, hip loading, supination, and kinetic chain efficiency. Paul uses multi-camera analysis and speed tracking in his sessions, providing detailed voiceover breakdowns that help players understand exactly where power is created or lost throughout their motion.
