This is my seventh week doing intermittent work on level 5. This week I did 20 rounds for L5D1 on Monday.
Then on Saturday, I pulled off the L5D3 test in 4:52. The pull-up sets were 6-5-5-4-3-3. The push-ups were 30-21. The squats were straight through. Form was solid, although not perfect. I took advantage of a little bit of a jump for the first pull-up of each set, but there was no swinging. The push-ups were at least down to where my upper arms were parallel with the ground, but I didn't hit my chin/chest on every rep. The squats were likewise probably not always as deep as I do them for the D1 routine.
Now on to level 6. The last time I was on level 6 was in 2012 and it took 7 months on level 5 to get there. What was different? This time around I have been doing more of a "greasing the groove" type routine. I have been building up push-ups, chin-ups, and pull-ups with smaller sets throughout the day. So, my conclusion is that for me, anyway, just focusing on Simplefit didn't produce progress as quickly as the greasing the groove strategy.
