I loved this one too. My glutes, lats, and pecs were sore for 2 days afterwards. I also like that they only repeat the rounds once. When I do PHA #1 I normally do the premix where you only do two rounds. Although in PHA #1 there are only do 6 exercises per round whereas PHA #2 there are eight exercises per round. ChelePA is right with the side lateral raises, they alternate bringing the weights to the side of the hips and to the front of the hips. I was confused at first as I expected a side raise alternating with a front raise and it took a few reps for me to realise what they were doing.
