Wales captain Rachel Taylor has warned England that her team's fitness is "much improved" ahead of their Six Nations match.
Wales have only beaten England once in their history, when a Non Evans penalty led to an upset in 2009.
Taylor says Wales will not be an easy target when the teams meet on Friday, in spite of losing all three of their games so far this season.
"I think our physicality and our fitness is much improved," she said.
"There's a few things that we're working on to try and get outside of their defence, and that will be something we'll focus on again tonight in training."
England come into the game on the back of a narrow win over Ireland.
