6 Ways to Level Up Your Daily Walk

leave a comment »

Emily Pennington has an interesting article (gift link, no paywall) in the NY Times. You can read the entire article at the (gift) link, but here’s what she says about Nordic walking, the first item in her list:

Originally developed in Finland as a way to train cross-country skiers during the off-season, Nordic walkers use specially designed poles with rubber tips to grab the pavement and help engage the arms and core muscles, turning a simple walk into a full-body workout.

Trekkers who can stomach the goofiness of city walking with sticks will see, on average, a 22 percent increase in calorie expenditure and will consume 23 percent more oxygen. The more oxygen your body can consume, the more effectively it can generate energy during workouts.

Companies like Leki and Black Diamond sell various expensive, high-tech poles for would-be hikers, but proper technique is more important than the label. “Whether you use a pole with a handle and strap, or two sticks, the focus of ‘Nordic’ should really be on the fact that you’re using anything to engage your upper body,” said Kirk Shave, who trains Nordic walkers at Mountain Trek Fitness Retreat and Health Spa in British Columbia.

He said that you should hold the poles with your elbows bent at a 90-degree angle and your forearms parallel to the ground. [Wrong, wrong, wrong. – LG] Next, you should use your triceps to press the pole tips into the trail behind you and push off, propelling your body forward.

“The No. 1 problem for hikers, runners, walkers is ultimately knees and ankles,” Mr. Shave explained. Taking some of the strain off the lower body by using poles while walking on flat terrain and down hills can help avoid compression issues in these joints, he added.

Serious error in that report

The information regarding having one’s elbows bent at a 90-degree angle with the forearms parallel to the ground is simply wrong, according to my experience and my instructor. That position places the poles in front of you, which works for trekking poles, where you exert pressure straight down. But when you’re using Nordic walking poles, your arms swing freely and push back, to help propel your body forward. In Nordic walking, one’s arms are straight or only slightly bent — see the two videos in this post.

The Riddle That Seems Impossible Even If You Know The Answer

The key is that if you start with the box labeled with your number, then either you arrive at a box that contains that number or you open boxes endlessly. Given that there are a finite number of boxes, that’s impossible. So by starting with the box labeled with your number, you know that you are in the loop with a box that contains your number. The only issue is whether that loop is 50 boxes or fewer.

Rosy shave

My Simpson Emperor 3 Super evoked a very nice lather from Dr. Jon’s Rose of Phrygia, and the impeccable vintage white-bakelite Merkur slant removed every trace of stubble. A splash of D.R. Harris aftershave, and I start the day feeling great.

The tea this morning is Murchie’s Storm Watcher, since it’s raining again: “perfect for sipping while safe and snug indoors with a good book in hand.”

And in honor of the holiday:

Revising Recipes in a Whole-Food Direction

leave a comment »

I follow a plant-based diet — a diet that excludes meat, dairy, and eggs. A person’s diet, whether omnivorous or plant-based, can be a bad diet. The Standard American Diet (SAD) is an example of a bad omnivorous diet; a plant-based diet of white rice, potato chips, jelly sandwiches, and soda pop would be a bad plant-based diet. It’s important that a person’s diet satisfies the basic criteria for a good diet.

A large body of nutritional research strongly supports following a diet that excludes meat, dairy, eggs, refined foods, and highly processed foods manufactured using industrial processes from refined ingredients, generally with added sugar, salt, and cheap food oils (like soybean or cottonseed oil), along with artificial colors and flavors and enough preservatives to ensure a long shelf life. (That sort of “food” is generally sold packaged with a brand name.)

Thus research indicates that the healthiest diet is a whole-food plant-based diet, which consists of foods that are either not processed at all (for example, fruit) or minimally processed (for example, chopped and perhaps cooked). Eating a good variety of whole plant-based foods provides a diet that satisfies the essential criteria. (Useful templates to ensure variety: Dr. Greger’s Daily Dozen and Dr. Heber’s food-color guide.) Such a diet includes ample amounts of high-quality protein — see this comparison of protein from plants vs. protein from animals.)

So when I find a vegan recipe that includes highly processed ingredients, I will generally try to swap those out in favor of whole-food ingredients — as I did in an earlier post for the Spicy Avocado-Lime-Cilantro Sauce. Substituting whole ingredients (like garlic and onion) for highly processed ingredients (like garlic powder and onion powder) will also generally make the dish taste fresher.

You can find (much) more information in this post.
