If I remember correctly the idea was to progress to the duration of the set at given RPM. Both of these can be set individually, depending on the goal. Say, you want to compete in GS, choose LCCJ and so have to progress to 10 minute set. You start with - say - 16 kg bells, lift at 5 reps per minute for 2 minutes. Next session - same weigh and RPM, progress to 3 minutes and so on. When you manage to do 10 minute set you can increase RPM and start from 2 minutes again. Once you get to what you think is meaningful RPM then you increase the weight.
Are you sure you are talking about the AKC Fitness Template that I attached? Because it never proceeds to 10 minute sets. It's more of an escalating density protocol, where the longest possible set is 6:00 (i.e., 3:00 per hand). At "Level 20" you would do 6:00, rest 00:30, do 6:00 of a second exercise, rest 30 seconds and do 6:00 of a final exercise. Take a look at the template. Also, under this protocol you only ever use one bell, never two, so there's not much connection to GS-style jerks or LCCJ.
Initial duration, weight and RPM - up to you. Never a problem to start too low/slow/short. It would let you "get into gear" and you can quickly progress to the parameters that become meaningful to you.
Again, it sounds like you experienced something rather different than the AKC template that Shaf provided. According to what I have uncovered, the initial weight, duration of set, rest periods, and RPM are all defined.
I didn't like this template. The problem starts when the weight becomes significant. Then you will have several sessions where you have to do long sets with heavy weights - 5, 6, 7, 8, 9 and 10 minutes. Too much of a load in my opinion. Rudnev was all about waving of the load. He even had this metaphor comparing the load with ECG: constant load is straight line, the ECG of a dead person; varying amplitude - ECG of a normal person. He was also big on supplemental training - circuits etc.
That's very interesting and something I am wondering about with regard to this protocol, but as I pointed out earlier, you will never go beyond 6:00 sets in this template. I think that V. Fedorenko considered 6:00 to be adequate for non-GS specific training, because I notice that his Kettlebell Pentathlon was set up the same way (five exercises for a six minute set each). However, the point about a steadily increasing load is well taken and I like Rudnev's parallel to an electrocardiogram.
If I think about it, the "wave" effect would happen between weights. Once you have reached Level 20 at a given weight, or with a given trio of exercises, you back down to Level 1 where volume, etc. drops way back.
Thoughts? I appreciate your viewpoint as you have dealt with many of these people in the past when I was pretty much ignoring all of it.
