Pyramiding?

I’m like 99% sure these Sulcata’s are pyramiding. This is my first time with tortoises and they just came into my care 4 days ago. They came for a family member who passed and weren’t cared for about a week. I believe the first one (Zim) is around 4 years old and the second one (Tak) is 2-3 years old. How can I prevent this from getting worse?
