Relax Watch the others , do as they do when bowing etc . You can control how fast you practice . After taking ukemi , don ' t race up to your partner again , take your time . Tell your partner that you are new , and that you are not comfortable with a particular ukemi . If everybody does kotegaeshi with free fall , tell them that you cannot do that yet . Relax . Even if everybody else is more experienced , the other guys likely are not used to 2 x 5 hours of Aikido in two days , so most everybody will be huffing and puffing after an hour or 3 . Try to enjoy the experience . When taking back falls , try to slap off with your arms legs high instead of doing a back roll if space is tight . Oh , and especially when throwing someone , look , and look again that you are not bowling them into someone else . Everything is likely to be very cramped .
