Hey everyone,
I mastered PE1 progression all right. I was on week 9 of PE2. However, I noticed that when performing these exercises, my neck hurts A LOT. I have a lower back injury and also I have absence of cervical lordosis (i.e. my neck vertebraes are missing their natural curvature or are "rectified"). I was wondering if I could skip all the way to PE4, AS LONG as I still do the mobility for PE2, and PE3 as part of my warmup? Is this advisable?
