## Playing style and coaching

Muchová is an aggressive all-court player, possessing an intelligent game with exceptional variety. She has powerful groundstrokes from both wings, using both her forehand and backhand to hit winners from any position on the court. She has been praised for her ability to incorporate softer shots, such as drop shots, lobs, and sliced backhands, into her game, constantly breaking up the pace of baseline rallies, and being able to hit winners with these typically defensive shots. She possesses a strong serve, with her first serve peaking at 110 mph (180 km/h) and averaging 103 mph (166 km/h), allowing her to serve aces frequently; she also possesses a second serve that, despite averaging 83 mph (134 km/h), possesses a high amount of topspin, meaning that it can be deployed effectively without being attacked by aggressive players. Muchová is also proficient at defending her second serve. Her footwork, speed, and anticipation allow her to be one of the strongest return players on the WTA Tour. As a result of her exemplary fitness, she is capable of sustaining long rallies, and is an effective counterpuncher, extending rallies until she can create an opportunity to hit a winner. Due to her doubles experience, Muchová is a strong net player, and is one of the strongest volleyers on tour, frequently approaching the net to finish off points. Throughout 2019, her breakout season, she was praised for her style of play by Mats Wilander, who stated that she could "achieve great things". With her on-court demeanour, fluid style, grace, and variety, she has been compared by some commentators to Justine Henin and Roger Federer.
Muchová has had several coaches in her career: Emil Miške (2017–2019, Apr 2023–), David Kotyza (2020–Aug 2022), Jan Blecha (Sep 2022–Apr 2023), and Kirsten Flipkens (2023–).
