Hi Bailey,
Thanks for your question. Can I ask first, what equipment are you using? What rubbers and how old are they?
If you watch our video on how to generate more spin with the forehand topspin: https://tabletennisdailyacademy.com/videos/how-to-generate-more-spin-with-the-forehand/ from 35 seconds Tom explains how to brush the ball very well. Has this video helped? Please let me know how you get on.
Thanks,
Dan
