DonnaJean Wilde turned a demanding core exercise into a five hour test of endurance at the Huntsman World Senior Games in Utah. The Canadian grandmother, who is 61 years old, held the female abdominal plank long enough to beat her own world record by nearly 30 minutes.

Wilde completed the feat on Oct. 4, according to Storyful. Her attempt began at 3:03 p.m. and ended at 8:03 p.m., putting her in the plank position for exactly five hours.

A spokesperson for the World Senior Games told Storyful that several judges rotated in and out of shifts during the attempt. Their coverage continued throughout the full period, from Wilde’s afternoon start to her evening finish.

The accomplishment gave Wilde a new mark after she had already secured the female abdominal plank world record. Storyful reported that the Utah performance surpassed her previous time by nearly half an hour.

Her latest record is still pending review and approval by Guinness. The reported achievement nevertheless represents a substantial improvement over the earlier record listed by the Guinness Book of World Records.

Wilde set that previous mark on March 21, 2004, at the Canadian high school where she once served as vice principal. Her recorded time on that occasion was 4 hours, 30 minutes and 11 seconds.

Guinness specifies strict positioning requirements for anyone attempting the record. "To successfully achieve the record, the challenger’s forearms and toes must touch the ground at all times," Guinness states.

The rest of the body cannot rest on the floor during the attempt. "The remainder of the body must be lifted off the ground and be kept straight throughout," Guinness also says.

Wilde previously described the physical strain she felt after completing her earlier record. "My elbows hurt pretty bad," she said.

She also explained how intensely she concentrated on maintaining the required position. "I was so worried about losing my form, and I think that’s why my quads hurt because I was just really tense."

Wilde told Guinness that the first two hours "went by quickly," while the following two hours proved considerably harder. Her effort became particularly demanding as she moved into the final portion of the extended plank.

"The last hour was the most challenging, just to stay focused and keep my form ," Wilde said. During the final 30 minutes, she concentrated on "breathing, staying calm and not shaking."

Planking became part of Wilde’s daily routine years ago after she broke her wrist. She discovered that she could still perform the exercise while wearing a cast, allowing her to continue being active despite the injury.

The position also allowed Wilde to combine planking with other activities. "I realized that I could read and do things when I was planking and fell in love with it," she said, according to the report.

Wilde encouraged other people interested in holding extended planks to continue practicing. "Keep trying and keep practicing. When you have to read or work on your computer, just get on the floor and do it on the floor."

Guinness reports that Wilde has 12 grandchildren. Her five hour performance at the Huntsman World Senior Games now awaits Guinness review and approval before the new record is confirmed.
