"This was the first time (I skated) with (other NHL players)," Selanne told Iltalehti, adding that he had been skating four times per week in July.
The nine-time NHL All-Star indicated that he's "healthy," and hasn't been running track or playing tennis this summer, which is why he's done more on-ice training.
Selanne hasn't officially made any decisions for next season, but all signs point to him returning for one final year.
"I'm ahead of the biggest decision of my career," he said. "I have three options I can choose from."
The native of Helsinki, Finland, will either re-sign with the Anaheim Ducks, join another team (though that appears to be unlikely), or retire.
A motivator for Selanne is the upcoming 2014 Winter Olympics in Sochi, which he admits he's very "interested in."
In 1,387 career NHL regular-season games with the Winnipeg Jets, Anaheim Ducks, San Jose Sharks and Colorado Avalanche, Selanne has accumulated 675 goals and 755 assists for 1,430 points.
