That’s interesting. I am pretty 2a.
I am currently alternating between 3-4 week accumulation+strength blocks and 2-4 week intensification+power blocks.
During the accumulation+strength blocks, I have basically been doing something similar to a GVT “ramp” or rep ladder every workout, but undulating the reps used. So for example, I may start the block by working up with 3s to a 3 rep max over 7-10 sets, then in the second workout I will use 4s, then the next week I will do 2s and and 5s and and then in the third week I will do 1s and 6s, so I have one ramp that is losing reps each week but going higher and one that is gaining reps each week. I may add a fourth week with a 3-2-1 wave and a 7-5-3 wave, or sometimes I will do 4-5, 3-6, 2-7 and then have a max week. The lower rep ramps are then used to lead into supra-maximal, and the higher rep ramps are used to lead into assistance or lighter layers.
I didn’t know that people were using 6RM ramps, but it really works for me to have 2 ramps running, one that is gaining reps and one that is getting heavier during an accumulation block of training. It’s neat because you may end up hitting the same weight on a 5RM layer that you hit on a 3RM layer at the start of the block.
