This is the first one I’ve looked back at and wondered what was I thinking.
Now if I were to program this the main purpose would be to lactate power in lower body during front squats. I’d also lower the percent to somewhere in 50s range so the athlete get more contraction.
As for the handstand hold it’s purpose would be to improve the system ability to pump the blood from lower to upper, which is a regular thing in a CrossFit workout. Lastly holding isometrics under duress is a great opportunity to focus controlling breathing.
