Hey everyone. I'm curious, I'm planning on attending the AOSB briefing and have seen that you need to do sit-ups (50 in two minutes, right?) My question is, do you have somewhere to place your feet or someone to sit/stand on them? Because I've been practising and have always done it by placing my feet under the sofa. Is this wrong? Should I be practising with nothing on my feet whatsoever? Thanks.
