My 2hbh used to be my very favorite shot--it was a fluid stroke, powerful, and I could generate a decent amount of topspin, plus hit deep shots and place them well. Suddenly my backhand is entirely on the fritz. It seems to pop up a lot (moonballs--AUGH!), slice when I don't mean to, or else I just have NO power--can rarely hit past the service line. In other words, I hit these really spinny or scoopy lobs all the time, or I kinda mishit it and it bloops along, barely over the net. I know I'm doing something differently because it tweaks my back while it used to be a totally comfy motion. It also sometimes hurts my wrist to hit a backhand. I'm at a loss, because I've never had to really think about my backhand. It's always just been my best stroke, even when I would occasionally switch to a 1hbh (I only use a 1hbh for slice, normally) for topspin backhands, and that was also very natural. Now I can't do 2h or 1h AT ALL, plus it's become physically painful (lower back). I've decided that one or a combination of the following might be involved: 1) tight wrists, 2) insufficient shoulder turn, 3) short backswing, 4) hitting too early/too late/general timing issues, 5) not keeping my weight forward, thus hitting off my heels, 6) low racquet speed, 7) grip (racquet too open), 8) hitting too far from my body, thus trying to "arm" it over, 9) new racquet giving me trouble, 10) poor footwork, 11) loss of confidence, 12) frustration. That's a lot of factors to consider. Can anyone help me narrow it down, or at least highlight the more likely culprits? Y'all know things. Please share. And please, pretty pretty please, don't tell me to use the search function! I wanted to describe specifically what's going on with my backhand in particular. And I'm sorry I can't post video, but I'm not that technologically advanced. Thank you thank you thank you thank you in advance advance advance. Advance.
