there are 2 ways of disengaging iliopsoas and doing abs - either pull legs back as u crunch, meaning active hip extension

>abs aren't attached to legs bot, at all :D u just need a way to stabilize pelvis and disengage iliopsoas & rectus femoris while u crunch for abs, this is the way:
>>and abs are easily isolated from iliopsoas when u hook heels on edge of bed and pull down as u crunch, pull heels to ur ass and down - switches off iliopsoas, gives u abs in weeks cause it's again noobz gainz - new stimuli
so u move upper torso in relation to pelvis, but u can also move pelvis in relation to fixed upper body
>dragon flag? but u said hooman it's all iliopsoas and rectus femoris and is retarded and will injure lower back and no abs will be mad
all true bot-bottom, so u bend legs in knees and hips and lift entire setup up, do not roll on your spine - no, lift up :D the squeeeze on abs especially upper abs - TREMENDOUS
flexing hips all the way switches off iliopsoas because it's got too much slack to do anything in this case
