Disclaimer: I am not a Master of Sport and this is by no means the only way to train with kettlebells. There are many programs out there and different coaches have different methods. These methods are what i have gathered from various sources.
Priorities in kettlebell lifting:
Technique
Choose a kettlebell weight that is relatively light and allows you to have consistent technique (RPT) of 8/10. Err on the lighter side if you don't know. Also if you can't do a competition lift with RPT of 8, do a lower sophistication lift and work your technique.
Volume
You have to do a lot a lot a lot a lot of volume in the competition lifts to be proficient in them. Every rep you do you are improving the skill of the lifts. If you can only remember one thing, it is this.
Duration
Your sets are measured in minutes. The goal is to work longer sets. Work your way up from one minute to ten minutes (or more).
Tempo
Measured in reps per minute (rpm). Minimum recommended is 4rpm for jerk, 10rpm for snatch. When you have reached ten minutes with a certain tempo. Drop the duration and start over increasing the tempo by 1rpm.
Weight
This is the last priority. When you have hit a certain number of total repetitions with a certain weight, it is time to move up a weight and start over the progression. Some recommended numbers:
-2 Arm Jerk: 100
-1 Arm Snatch: 200
-2 Arm Long Cycle: 70
