resistance by pushing your knees with your hands and pulling your knees against your hands. continue to breathe normally and hold the resistance for 10 seconds. return to your starting position using slow and controlled movements and then repeat two additional times. would likely look something like this. i don't know if that would make a difference, but that's definitely something to consider.
i definitely don't think it should just be abandoned. if anything, it's more to think about! but those are just my own thoughts.
