If you're concerned about your technique and you're training alone. Video yourself lifting and send it to people or post it on here. Don't work on general strength stuff cause it will_never_help you become a better lifter, I've seen people that back squat 200kgs and can barely snatch 70.
Weightlifting is like golf, if you want to get better at it then hit golf balls, swinging a weighted bat will not improve your golf. If you stick to snatch and cj you WILL get better at it.
Not a lot of volume. In the morning I hit max power snatch/clean. In the PM I max out then deload (-10kg from last successful attempt) for 3 doubles or I'll go back down and max in the hang. On my "off" days I just work to a max in powers, pause at the knee or maybe doubles.
It took me about 6 months to get pretty efficient with the lifts. After 5 months I was doing two-a-days, so my learning process was sped up. The main thing you want to focus on is sticking to snatch and clean and jerk. Don't be doing pulls and things like that. I lift at a gym 3 times a week, the other 4-7 sessions are alone in my garage.
Right now my snatch is close to 90% of my CJ. I think roughly 83% is the typical percentage so I wouldn't say my ratios are dead on. I don't usually worry about that. As Jon North says, "I aint got time for percentages." I just max out, If I was snatching 100% of my CJ I'd still be happy.
Technical assistance is any lift related to the competition lifts which aren't the full lifts. As for max lifts during contest prep you move up the highest lifts to 95%. true 100% lifts are for competition only. Training max changes everyday, and its wise not to go to a true max until competition. Training is to provide volume of technique and fatiguing work.
