Great tennis isn't just about hitting the ball hard – it's about having flawless tennis form: perfect posture, balanced movement, efficient weight transfer, and smooth biomechanics. Even small form flaws can rob you of power, consistency and injury resistance.
In 2025, the best players and coaches rely on advanced tennis form analysis to spot and fix these subtle issues. OnCourtAI takes this to the next level with AI-powered analysis that processes over 30,000 data points from a single 30-second video, examining more than 40 phases of every stroke to give you professional-level feedback instantly.
No more relying on 'feel' or waiting for your coach to notice something. Our tennis form analysis tool catches everything – from slight posture imbalances to inefficient footwork patterns – and shows you exactly how to fix them.
Why Tennis Form Analysis is Essential for Improvement
Poor form is the silent killer of tennis performance. It leads to:
- Reduced power and spin generation
- Inconsistent shot placement
- Higher injury risk (tennis elbow, shoulder strain, lower back pain)
- Slower recovery between shots
Traditional coaching can spot major issues, but subtle form problems often go unnoticed. OnCourtAI's tennis form analysis changes that by measuring every aspect of your body position and movement with scientific precision.
Players using regular form analysis improve their overall technique efficiency by 29% on average within 8 weeks – backed by OnCourtAI research.
How OnCourtAI Revolutionizes Tennis Form Analysis

- Movement Efficiency: Split-step timing, recovery steps, court positioning
Key Form Elements Our Tennis Form Analysis Examines
Posture & Balance: The Foundation of Great Tennis
Poor posture is the root cause of many technical issues. Our analysis tracks:
- Spine alignment throughout the stroke cycle
- Shoulder level consistency (prevents 'arm-y' swings)
- Centre of gravity position and movement
- Head stability during contact
We find that 60% of club players have excessive forward lean on groundstrokes, reducing power transfer by up to 20%.
Footwork & Movement Patterns
Efficient movement is crucial for consistent form. Our tennis form analysis measures:
- Split-step timing and depth
- Weight transfer efficiency
- Recovery step patterns
- Court positioning relative to ball trajectory
Players improving footwork patterns through our analysis win more points in extended rallies.
Stroke-Specific Form Analysis
Each stroke has unique form requirements:
- Serves: Trophy position posture, spinal extension, landing balance
- Forehands: Unit turn completeness, hip-shoulder separation, finish position
- Backhands: Non-dominant arm extension, torso rotation, follow-through balance
- Volleys: Knee bend depth, forward weight commitment, head position
