Sheffield United players swapped hitting the net for hitting the punch bags as pre-season training took a somewhat different path than normal.
Coaches from Sheffield City Boxing Club put Blades, including new signing James Wilson, through their paces at the English Institute of Sport in Sheffield and it didn't take long for the footballers to work up a sweat.
Starting off with perfecting their stance, the players eventually took out their frustrations on the punch bag and quickly realised how hard boxers work in their own training.
However, as tough as it was, striker Billy Sharp was happy to try something new.
"It was enjoyable, it was good to do something different rather than football," he said. "It was good of them to show us their sport and we appreciate their time out in taking us. It was hard work."
As different and difficult as it was, Sharp admitted that pre-season under new manager Chris Wilder has been impressive as a whole, with the emphasis on improving technique rather than energy sapping runs up hills.
"We've obviously been doing some running but we've had the balls out from day one so credit to the gaffer he's let us have the balls out and get used to those straight away," added Sharp. "After the first week we've improved on the ball and in our fitness. We've got five weeks to get to full fitness but the gaffer's wanting us to be right at it and be as fot as possible as quick as possible."
