In tennis, the forehand (the shot hit with the dominant arm) is typically faster and stronger. Consequently, the dominant side develops and strengthens naturally through continuous play on the court. However, the non-dominant side used for backhand shots might be neglected. Without proper attention and training, the non-dominant leg may become weaker in terms of strength, coordination and quickness.
The disparity between the dominant side and non-dominant side creates an imbalance, commonly referred to as "lazy leg syndrome." This can impact movement efficiency and lead to difficulties while playing tennis, especially when making quick lateral movements or changing directions on the court.
Preventing "lazy leg syndrome" requires balanced and consistent training that targets both the dominant and non-dominant legs and sides of the body. This can involve exercises focused on strengthening the non-dominant leg and improving its coordination and speed.
