The only times pair skating partners can give each other assistance in executing lifts are "through hand-to-hand, hand-to-arm, hand-to-body and hand to upper part of the leg (above the knee) grips". They are allowed changes of hold, or going from one of the grips to another or from one hand to another in a one-hand hold, during lifts. There must be one full revolution after a change of hold is made for it to count towards a team's score, but the man can change holds from his left to right arms, or from his right to left arms, with at least one revolution in each hold. Teams earn fewer points if the woman's position and a change of hold is executed at the same time. They earn more points if the execution of the woman's position and the change in hold are "significantly different from lift to lift". Teams can increase the difficulty of lifts in any group by using a one-hand hold. A lift is judged illegal if it is accomplished with a wrong hold.
