i spent an hour today working on the 1hbh. my first session. felt good. but there are still technical doubts. i have a trainer who is not techn sound, his own bh is poor. so i have read from various places and need to get doubts clear. 1. trainer says "throw your racket forward". is that correct? 2. one video said keep wrist locked. yes/no. if i throw rack forward, then i cant keep wrist locked. 3. some videos and pics show rack face high at takeback. my trainer says keep rack head low. vids of gasquet and henin show high racket face at start then it loops down in a C like motion. which is right? btw, when i lock wrist racket face goes high. i found keeping the wrist locked usually gave a better stroke. i try only moving shoulder, but trainer criticizes that and asks me to throw rack forward. Added later: I just checked earlier threads, some people have suggested locked wrists. i once again checked the ipodtennis video, the players says keep buttcap facing down at start, so it seems high racket face is correct. thx.
