Video Analysis

Here's the video that both Ali and Martin reviewed and commented on. Thanks to Erick Hong for participating in the video shoot. Even though it seems I won most points, Erick did beat me.

Video-study case: The AIM-X coaches have reviewed recreational tennis players and have with the video screening come up with findings that are shared below the video. The exercise that AIM-X provides as the ones that can be done for improving performance, in this case, Split-Stance are also shown under the Video analysis. 

Primar findings of the analysis:

  • The player (me) is often not performing Split Stance 
  • This makes the player being to late in preparation before most of the strokes
  • The player need to work outside and inside the court with the Split Stance

Although the player in question only plays once a week, the coaches said that he has the potential to develop his game by training on Split Stance (working with the feet) and not least playing more frequently.

Drills: Specific drills to improve Tennis split-stance;

  • Split Step to Shuffle

  • Split Step to Sprint

  • Split Step to crossover

  • Split Step to Crossover Behind

Split stance exercise should be done both outside the Tennis court. If you struggle with the Split Stance as I do, the continuous and repetitive performance of the shown exercises is key. 

Reviewing the exercises:

  • Stand tall throughout all exercise, that is an Athletic position when starting the drill
  • Try to move as rapidly as possible after performing the Split Stance
  • Implement the drills every time you hit the court - performing the drills as a warm-up for example. 
  • Quick feet and being in position all the time are key in Tennis. Improving the basics will give you a better foundation in your playing style.
