Parramatta have continued their recovery mission, adding rugby league's most decorated trainer, 65-year-old fitness guru Ronnie Palmer, to their training staff.

Palmer, who was tapped on the shoulder by the Panthers as part of Anthony Griffin's overhaul, will join the Eels in November as the newest member of the club's high-performance unit.

The veteran trainer, with a body that still puts some professional rugby league players to shame, said he was leaving Penrith with a heavy heart but excited about the prospect of helping Brad Arthur rebuild the Eels.

"It's just a matter of the situation that's prevailed," Palmer said. "I'd still love to be at the Penny Panthers because it's taken five years to develop a really good team and culture and I think it's only going to get better.
