I'm trying to better my footwork and recently to incorporate more crossover step into my game, but I'm getting conflicting messages from different sources. Right now the most common time I'll use it is on my approach shot. But I want to start using it more on my baseline attack. When's the right time to shuffle/ crossover/ run along the baseline? And to confirm, crossover step lets you cover more ground correct? Because I had a friend that was telling me you use it is for smaller movements? Do you have any good drills or scenarios to practice this out? Thanks as always.
