I'm actually quite baffled on this idea. Are you supposed to stay on your toes throughout your entire groundstroke, on both backhands and forehands? I remember BB stated something about this when posting about forehand technique on IwishIwasBetter's thread, but I wasn't sure if he meant you're supposed to stay on your toes during the ENTIRE forehand. This video also threw me off: I was unsure whether or not Federer was just playing around. http://www.youtube.com/watch?v=1ImeQaAyFPc&feature=related At many times throughout this video, it appears that he is flat-footed on several strokes. Is this just him playing? Or did I not catch that he's still on his toes? What is correct technique? On your toes ALL THE TIME? ...or you can put your heel down, specially when loading up on your shot?
