Lower back feeling during pancake work

Hi all, Id like to check with all of you. How does your lower back feel during pancake work in MS-series? 

To describe it for me I wouldnt describe it as pain but more like fatigue especially during the last 1-2 pancake exercises. Would say its a 3/10 in the pain scale. Is this ok or should I recheck My form? Trying to hold a APT full sets and knees to the seiling always. Would really Appreciate feedback on this.

by the way, i dont have/had any lower back issues.

Hi @Jonas Berglund, Yes it is completely normal to feel a slight discomfort and especially if you are feeling fatigued from the series. When in doubt, send a video for form check.
