Intro: The wall never misses.

This simple but effective solo drill — hitting a tennis ball 100 times against a wall — sharpens your reaction time, consistency, and feel for the ball. Whether you’re a beginner or advanced player, this RB100 Challenge tests your precision and focus under fatigue.


The Rules

  • Use a racket and tennis ball (soft or regular)
  • Find a solid wall (tennis court wall, garage, gym, etc.)
  • Keep the ball alive for 100 continuous hits
  • Reset the count if you lose control

Why This Works

  • Trains timing, accuracy, and footwork
  • Builds mental focus and physical endurance
  • Great for warm-up or conditioning days
  • Can be adapted for squash, paddle, or racquetball

Tips for Success

  • Stand 2–3 meters from the wall
  • Use your dominant and non-dominant hand for balance
  • Focus on rhythm and recovery between hits
  • Try forehands, backhands, or alternating strokes

Upgrade the Challenge

  • Add footwork (side steps between hits)
  • Use a smaller racquet or foam ball
  • Aim for a target zone marked on the wall
