From a reader ( and a chiropractor) via email
“I have a a question regarding the movement “Toes2Bar”. I have several die hards for patients and despite my best efforts to educate them, they just never seem to be able to wrap their head around the fact that all this lumbar flexion and high volume are causing back injury. That being said, I wanted to get your take on the amount of lumbar disc loading that might go on during this toes2bar movement. Personally I have tried them and I do notice my back is sore the next day. Just wondering if you thought this movement might load the spine less than an actual situp or crunch, similar to the SL situp you advocate.”
My response-
1- I recently heard an anecdotal report about a severe skull fracture from losing grip on Toes-to-the-bar. Most people use momentum to get the last few and if grip fails the results could be catastrophic.
