Add strengthening exercises to your walking workout to build muscle. Even though strength training does not burn considerable calories, it replaces your fat with lean muscle mass. Your body works harder to sustain your muscle mass, raising your resting metabolism so you burn more calories throughout the day. Invest in light hand weights or wrist weights and pump your hands as you walk. Build lower body muscles by lifting your knees high during part of your walk. Stop every five minutes and do a series of squats or lunges.
Surgeon General: The Surgeon General recommends 30 minutes or more of accumulated moderate intensity physical activity on five or more days per week to improve health and fitness. "Accumulated" means you can do it in shorter bouts throughout the day (for example, 10- or 15-minute intervals throughout the day), and "moderate intensity" means you feel warm and slightly out of breath when you do it. You can read more about the Surgeon General's "lifestyle" recommendation at:
Structurally diverse aromatic chemicals are degraded via the common products such as catechol, protocatechuate, gentisate, hydroquinone (benzene-1,4-diol), homoprotocatechuate, dihydroxyphenyl propionates, and homogentisate (Vaillancourt et al., 2006). The ring cleavage of catechol is performed by two distinct enzymes: intradiol oxygenases (utilize nonheme Fe(III) to cleave the aromatic nucleus ortho to (between) the hydroxyl substituents) and extradiol oxygenases (extradiol dioxygenases utilize non-heme Fe(II) to cleave the aromatic nucleus meta (adjacent) to the hydroxyl substituents) (Harayama and Rekik, 1989).
“Carrying extra weight will increase the intensity and your calories burned without requiring a lot of extra effort, depending on the weight you use,” adds Spraul. "You can hold dumbbells in your hands or put some heavy books in a backpack — whatever works for you! It doesn't have to be complicated. Just make sure that the added weight is not throwing you off balance.”
Before starting a walking program, check with your doctor if you have a chronic medical condition or if you have had a recent injury. But don't assume that you aren't able to start exercise walking if you do have medical issues. Exercise walking can help control disease progression and relieve symptoms in people with cardiovascular disease and diabetes, and many people with arthritis or other musculoskeletal problems will experience symptom relief from a medically supervised exercise walking routine. Exercise is an important part of all weight-loss programs that will help with many chronic medical conditions.
Here’s what’s happening in your body when you’re running and walking: “Muscle action that propels you from point A to B requires the utilization of a thing called ATP,” explains Janet Hamilton, an exercise physiologist and running coach with RunningStrong. “Your body stores only a limited amount of ATP (enough for only a few seconds of activity), so it needs to replenish that supply, and it does so by metabolizing your stored fuels (glycogen and fat). The process of making useable energy (ATP) from stored fuel (glycogen and fat) is dependent on how much you need and how quickly you need it.” So the more intense the activity, the greater the demand for fuel—and since walking is less intense and demanding than running, it doesn’t demand that ATP be produced at the same rate.
Triglycerides are a common form of fat that we digest. Triglycerides are the main ingredient in animal fats and vegetable oils. Elevated levels of triglycerides are a risk factor for heart disease, heart attack, stroke, fatty liver disease, and pancreatitis. Elevated levels of triglycerides are also associated with diseases like diabetes, kidney disease, and medications (for example, diuretics, birth control pills, and beta blockers). Dietary changes, and medication if necessary can help lower triglyceride blood levels.
Add Weights: Another way to add intensity to a walking routine is to use weights. “Whether you're on the treadmill or you hop off on your ‘rest interval,’ you can add weight to keep your heart rate up and add some strength training into the mix,” says Crockett. “While you're walking on an incline, adding some dumbbell shoulder presses or dumbbell jabs can help you tone your arms and burn even more calories. [Or] hop off the treadmill after your fast interval and try some quick high repetition exercises, such as dumbbell squats, squat to press, weighted jumping jacks or weighted sit ups.”
