From a Wall Street Journal online article:
Now 63, Mr. Peterson has progressed from bike paths to rugged mountain trails and is known for his caped helmet emblazoned with his nickname, UniGeezer. Based on his GPS and bike computer, he estimates he’s logged nearly 30,000 miles, or 24 million pedal revolutions, since he started.
He thinks there’s a fear factor that prevents more people from trying unicycling. “If you fall, 99% of the time you land on your feet,” Mr. Peterson says. His worst injury was a torn piriformis, a tiny muscle behind the glutes, from overuse.
Unicycling isn’t as trendy as spin class, but Terry Peterson says he sweats just as much and smiles way more.
In 2006, at age 50, Mr. Peterson was 30 pounds overweight and got winded climbing a flight of stairs. His job as a piano tuner in Lomita, Calif., was mostly sedentary.
Popular workouts like running, cycling and boot camp sounded boring. “I needed something that would constantly demand my attention and keep me entertained,” he says. He thought back to his childhood unicycle, googled his old toy and was wowed by online videos of Canadian off-road unicycling pioneer Kris Holm. “This wasn’t the cheap ride I had when I was 11,” he says. “He was on a real, purpose-built unicycle doing unreal tricks.”

Mr. Aiona paddles with his club on Tuesday and Thursday nights and Saturday mornings for 90 minutes to two hours.They alternate between sprints and endurance paddles of up to eight miles in a six-man outrigger canoe. They also work on paddle technique and do huli drills. “Huli is Hawaiian for turn over,” he explains. “If you flip your canoe there is a very precise process for getting everyone safely and efficiently back in. We call out positions to make sure no one is underneath.
This study, combined with the results of previous studies, supports the hypothesis that engaging in morning exercise may result in more weight loss compared to engaging in a similar amount of exercise later in the day. Furthermore, we observed individuals who performed most of their exercise sessions in the afternoon or evening tended to have slightly higher levels of EI and reduced NEPA and NEEx, suggesting that there are potentially important differences in the components of energy balance based on time of day exercise is performed.
“Living a healthy lifestyle may help offset a person’s genetic risk of dementia, according to new research.
Gravel riding is more jarring than road riding so strength and mobility really come into play. “Your upper body takes much more of a beating,” Mr. Wilwerding says. “Especially when you’re riding bumpy terrain for eight hours.” With the help of a coach, he has trained to participate in five century rides—three road, two gravel—this summer. His next ride, the SBT GRVL, takes place Aug. 18 and covers 141 miles and about 9,000 feet of climbing in Steamboat Springs, Colo. “I’m in the best shape of my life outside of my collegiate swimming career,” he says.
