I think this has been my biggest struggle so far in GST. I started it back at the end of June. I think I got as high as attempting step 8, though I'd probably lying if I said I matched the proper tempo as I tried to progress towards the beginning. I also did take a couple weeks off in September to rest a lower back injury. When I got back to step 6, I was struggling, so I instead of resetting back a certain number of steps, I did 24x5 for a week (2 sessions), 28x5 for a week, 32x5 for a week, then finally back to 36x5 this week to complete step 6. I'm going to continue making smaller jumps, as I just don't see being able to make the full jump up to sets of 48 reps. I don't have any older videos, but I'm extremely pleased with my progressed on the iM. If I'm not there yet, I have no doubt that I will be by the time I get to 60x5 on the PE. Thanks in advance for any feedback.
