If you do your own research you’ll quickly find out that hanging leg raises bias the hip flexor instead of the abs (unless you do a really specific/technical form adjustment that 99% of people are oblivious to and still doesn’t make it ideal for targeting the abs). It’s more likely that she just has good genetics and is lean if that’s her main ab movement. If you want to actually induce a lot of hypertrophy in the abs you need to do some form of weighted crunch in 7-15ish rep range.
Very true, hanging leg raises are very hip flexor biased. I’ve been doing them for almost 5 years now. It’s definitely difficult and takes intent to feel your core on the concentric, slowed eccentrics are always good for getting into the groove. You can also do crunch variations while hanging, so you get the full kit and kaboodle for core
Hanging crunches are basically what I was getting at with the technique adjustment, glad to see someone keeping the nuance around leg raises; a lot of people will just blindly/misleadingly call them an ab movement. If you haven’t, definitely try weighted crunches on a ghd if you have access to it. Possibly the greatest loaded crunch movement in history
