Yes I did do that with the one knee bent (modified version). The evening of that workout, which was pull/abs, I experienced outside hip pain when trying to sleep. I can’t figure out what other move that day which would have contributed to the pain. So I took a guess it was the side plank reach thru(modified). I thought maybe because I was holding up my bodyweight on the one side and maybe my pelvis isnt strong enough. Just wondered what would be a good alternative.
