Three-time Olympic medalist Lindsey Vonn is known for her intense fitness routines.
On social media, the retired skier typically posts her workouts inside a gym with her private trainers.
But starting in early March, when the Covid-19 pandemic hit and many states issued stay-at-home orders, Vonn had to get creative with her workouts when gyms around the country closed.
Vonn, 35, says she used everything from big bottles of bleach to jugs of Costco olive oil and even her dogs as weights while working out at home.
"My one dog, Bear, weighs about 85 pounds, so he was pretty difficult to squat with. And then Lucy is a little overweight [for a Cavalier king Charles Spaniel]. She's about 20 pounds, so I could use her for like single leg stuff," Vonn told CNBC Make It on May 29.
Vonn said she didn't attempt to workout with her third dog, Leo, who weighs about 95 pounds.
"I drew the line at 85 pounds. That was good for me," Vonn said.
Vonn also used household items, like a chair, to do step ups and she used her staircase for cardio.
"I would run up the stairs, run down and do side runs and long strides to keep the cardio going and get a good leg workout," Vonn said.
The key to staying consistent at home is to stick with a schedule, according to Vonn.
At home, Vonn said she works out five days a week, typically Monday through Friday, with her fiance, New Jersey Devils hockey player P.K. Subban. They usually workout from about 8:30 a.m. until about 9:30 or 10:00 a.m., she said.
During quarantine, exercise has helped Vonn cope, she said. "Obviously, it's been hard, just like it has been for everyone else. I definitely found that the more I work out, the better I feel mentally and physically."
Amid the Covid-19 pandemic, Vonn has also teamed up with Under Armour to share her at-home workouts and meal plans to help inspire people to stay fit and motivated.
She credits her success to being a hard worker.
"I was never the most talented skier, but I outwork people," Vonn said.
