Check out our articles section, under features. Check out the videos as Tom said. Check out our links. When I started weightlifting, there was nothing to be found on the sport anywhere yet I succeeded. Now you have immense information right here on this site at your disposal, if you seek it. I worked many hours to make it available.
It's tough to become beyond your original coach, but often the right thing to do.Educating yourself thru vids/books/classes will really help you to find the truth,both for yourself, and from what your coach has been trying to tell you.All good coaches develop a mutual teamwork w/ their athletes in seeking their best performance.Sometimes lifters bail on what could have made them great, sometimes coaches push them away.In the end, your lifting is YOUR baby.
Maybe you could post a video of your lifts?Sounds like Dr. Phil could chime in here on the relationship with your coach.Perhaps your coach is frustrated because you have not met his expectations?Perhaps some private feedback from some of your closest team mates would be enlightening.Don't be discouraged. Do you have a first meet you are working towards?Do you do full front squats? Do you wear weightlifting shoes?
Also, are you REALLY doing all your coach asks, or just kinda part-way?Lots of coaches' frustration comes from lifters not taking their opportunity seriously,rather than from frustrating obstacles that will be overcome eventually w/ diligence.Some coaches have no patience for the less-perfectly-talented, but if you really are putting in steady work w/o giving lots of lip, then a coach would have to be pretty limited to not understand how unpredictable development can be. Knowing all the stuff to help people achieve their best, AND patiently applying it thru thick and thin (of progress, not attitude) are not every coaches forte'.Try doing jumps from a medium box/bench, to the floor, exploding up to a high box/bench (that requires you to flex your knees and hips quickly and fully after major extension) -- this could help you transition from powers to fulls.Also, trying some Hip-SN and Hip-CL (no lowering as in Hang work) may help you gain the better ability to drop.
