The theme might be lingerie but the week will test the girls both physically and mentally. First Charlotte, Alex and Josh lead lessons in yoga, gym and tap dancing. Sophie realises her ‘guns’ are no match for Alex’s toned biceps but its Kathryn who really needs to work out more for her stamina. Jess takes to the downward dog at Charlotte’s yoga lesson and Amanda and Kelsey get an ‘A’ for effort from Josh but an ‘F’ for fail for their tap ability.
