Dean Mumm says that the Waratahs commitment on the training field has resulted in their improved form over the last three matches.
Prior to the Waratahs three match winning streak the 2014 Super Rugby champions had only managed to record two wins from six matches.
Waratahs prop Benn Robinson slammed the Waratahs effort on the training field back in March, and the squad seemed to have taken note of the comment as just under a month later they are looking in much better shape with three wins on the trot.
Mumm explained to WA Today: “When we look back earlier in the season [at] what we weren't doing, the standards of work on the training paddock wasn't as good as it needed to be, so we've changed that and that's been a little bit of a difference.
"It's little things. If you accept a couple of dropped balls on the training paddock when you're doing basic skill drills, they're going to flow through to the game."
Assistant coach Nathan Grey has often expressed his disappointment when performances were not going according to plan this season. .
"If you're blowing up for the sake of blowing up, there's not a lot of point, but if it's got a key point behind it and it's about setting the standards you need to be competitive and win matches, then we're all for it," said Mumm.
The Wallabies lock praised the Bulls scrum ahead of this weekends clash and added that the Waratahs will have to get themselves ready for a physical onslaught when they face the Pretoria based team.
He added: "Their scrum's going very well. They maul a lot as a side. If you look at the way they've scored throughout the season, a lot of their tries have come off set piece and that's going to be where they're going to come at us.
“We're going to have to have our physical game in order to make sure that we can be there and give ourselves the opportunity when it presents itself."
