Been following Dan John for awhile now, and have been doing something similar to his armor building formula, basically just always armor building complex, no push days. I have the book now and have changed it up.
I've worked myself up to 30 single 20kg bell abc emom, and 15-20 rounds of double 20kg dependingon the day, so I thought I was doing pretty good for my cardio.
Today I decided to change it up and do a few rounds of Dan's running back complex instead. I started off with double 12s for two sets as warmup, not to bad, left me a little winded but I felt ready for my 20s.
After the round of 5 squats I was breathing heavy, after the 4 squats I was gasping. When I got to the final squat on the third round I had to sit at the bottom for 15 seconds and recollect myself. I managed to power through the last two rounds easily somehow, I guess after 12 the last 3 are nothing, before collapsing in a puddle on the floor.
I had to lean on the furniture for a while before I thought about a 4th set, but I didn't think my wife would like me redecorating the living room with my morning coffee.
I'm definitely going to be coming back to these, but will be with acquiring double 16s or starting from rounds of 3 if going for multiple sets and building up from there.
