No offense taken, I just wanted to use your post as an opportunity to make a point.
1) get a coach
2) train with the coach
Now I taught myself the lifts too, and have hit some fairly decent numbers, but after 16 years of doing this stuff I'm now training with a coach. Why? I saw videos of my last meet and saw how sloppy my technique had become and I want to get things cleaned up.
That's my best advice!
PS: Oh, sorry, you said "WITHOUT" a coach!
