EDEN PRAIRIE, Minn. -- Adrian Peterson says it took him about a month and a half to begin lifting weights after his Feb. 7 sports hernia surgery.
Is the reigning NFL MVP back to lifting the same weight he was before the injury?
"More," Peterson said on Wednesday, grinning after the Minnesota Vikings' first open session of organized team activity practices.
His rehabilitation was "a cakewalk" compared to last year's recovery from a torn left anterior cruciate ligament, Peterson said, and his participation in practice confirmed his progress.
The Vikings let him complete every drill, including letting him carry the ball in 11-on-11 and 9-on-7 drills.
"I'm pretty much 100 percent," Peterson said. "Me knowing my body, I would like to be a little stronger in some areas. But I'm feeling great."
Peterson, 28, ran for 2,097 yards in the 2012 season -- more than half of them (1,068) in the final seven games, beginning with the Week 10 game against Detroit in which he was injured.
He rarely practiced but dropped out of only one game, on Dec. 23 at Houston, coming within 8 yards of matching Eric Dickerson's single-season rushing record (2,105 yards), set in 1984.
"As each game came along, I could kind of feel it getting a little worse," Peterson said. "But it's mind over matter, so I just continued to push and dealt with it."
Peterson said he "definitely earned a lot more respect for your abdominal muscles" and has been ramping up his weight training after initially gearing exercises to reduce pressure on the area.
He was one of 89 players on the 90-man roster on hand for Wednesday's session -- a remarkable participation level for OTAs, in which participation technically is voluntary.
"His attitude and the way he's approaching things is what you want to see if you're a young player coming in and trying to figure out this league," coach Leslie Frazier said. "To be around Adrian, it's good for our team, just good for everybody involved."
Jennings nicked up
Top receiver Greg Jennings was a surprise scratch for Wednesday's practice because of an ankle injury suffered a day earlier, in a session closed to reporters.
"His ankle's a little bit sore," Frazier said. "But he'll be fine. Nothing serious. He's on the side working with (head athletic trainer) Eric Sugarman."
Also sitting out were center John Sullivan (microfracture knee surgery), linebacker Michael Mauti (left knee reconstruction) and receivers Greg Childs (torn patellar tendons) and Chris Summers (ankle).
Childs jogged onto the field briefly for warmups before going inside for a rehab workout. He is less than 10 months removed from surgery.
Veteran end Jared Allen remains the only player absent from OTAs, which he hasn't attended in the past either. He's coming off shoulder and knee surgeries and had a family obligation this week.
