Jenkins has hinted that the mood in the Welsh camp is positive as Rob Hawley's side seek their first win of the competition in Paris on Saturday.
"Everyone in the squad is raring to go," Wales Online quotes Jenkins as saying.
"We were disappointed with the first half last week and the result and everyone is keen to get back on the pitch and get the match underway. It's a huge game for us and we can't wait.
"We started poorly last week but we put together some good rugby in the second half and we want to take that into tomorrow. However we know that we have to play that way for 80 minutes and we have to put France under as much pressure as possible."
Wales lost their opening Six Nations match 30-22 to Ireland last week.
