Hi is there an alternative to doing abdominal curls/100's without including table top. Just as a trial, because I would like to do a test to see if the table top and 100's are straining my hip flexors or not.
I know I can just do them without the table top and just keep my knees bent and feet on the floor. But don't feel that would be working my core as hard as if I included the table top. Is there a modification I could do as a trial?
