Tips for choosing the right exercise equipment

Tips for choosing the right exercise equipment

You can launch an effective exercise program using only what nature gave you: your body. But because regular activity remains an elusive goal for most people, a multibillion-dollar industry has blossomed around the promise of surefire success. Health club memberships and home exercise equipment are excellent exercise solutions for many people. Do keep these cautions in mind, though:

• Even the best equipment and most tricked-out gyms only produce results when used regularly.
• Learn to use equipment properly to avoid injuries that could sideline you temporarily or permanently.
• Exercise equipment comes in all sizes, shapes, and price ranges. It pays to check consumer ratings and follow our other tips for smart consumers before making your purchase.

Following are some basics you should know if you’re in the market.

Cardio equipment

If you stop by any gym, you’ll see rows of machines designed to simulate cycling, walking and running, kayaking, rowing, skiing, and stair climbing. Whether motorized or not, sized for heavy-duty gym use or in lighter home versions, these machines offer good cardio workouts that burn calories and fat. What’s more, your workout takes place indoors, away from fickle weather.

Price varies from a few hundred dollars to thousands, depending upon whether a machine is motorized or programmable, and whether it has add-ons, such as devices to measure heart rate, calories or METs burned, time elapsed, and so forth. While this information tends not to be entirely accurate, it could encourage you to step up your workouts or may be important if your doctor has advised you to limit activity. The following are some of the more popular types of aerobic exercise equipment.

Cross-country ski machine

This machine lets you exercise arms and legs simultaneously, as you would in cross-country skiing. The sliding motion is easy on the knees. On some machines, you have to move one ski forward to make the other move back. On others, the skis move independently. In addition, certain ski machines use ropes, while others have stationary handgrips. Check out all these types to see which one is most comfortable for you. Look for a wide foot bed for stability.

Elliptical trainers

These machines provide a circular up-and-down motion that’s a cross between a ski machine and a stair-stepper. They provide a nearly impact-free workout, which is easy on the joints. Resistance and grade can be adjusted automatically or manually on some models, and levers with handgrips to work the upper body may be available, too. It may take a little while to get used to the unusual motion. Look for comfortable handlebars and nonslip pedals with curved ridges. Try the machine out at varying speeds and grades to make sure it feels stable.

Rowing machines

Rowing machines work the back, arms, and legs simultaneously, offering as close to a total-body workout as available from a machine. Unless you’re used to rowing, the motion initially may feel unfamiliar, and some people find it hard on the back. When purchasing one, consider pulley models instead of piston models for a more realistic rowing experience.

Stair-steppers

These machines provide a low-impact workout that approximates climbing flights of stairs. Some modes have levers with handgrips to work arms, too. Beginners may find stepper machines strenuous, and the motion can be hard on the knees. Look for machines that provide independent foot action and are equipped with handrails and large stair platforms.

Stationary bicycle

An exercise bike takes no training and is easy to use, although it can be uncomfortable for long stints. While riding isn’t as effective in preventing osteoporosis as weight-bearing exercise, it does provide an excellent cardiovascular workout. Look for a model with a comfortable, adjustable seat and toe clips. If the seat is too hard, find out if you can replace the seat with a cushioned model bought separately.

Treadmill

This machine enables you to walk or run indoors. Some models offer a flexible, less joint-jarring surface. Opt for a motorized treadmill. When purchasing one, look for a strong motor (the machine will last longer), a belt that’s long and wide enough for your stride, a sturdy frame with front side rails for safety, and an emergency stop device. You should be able to adjust the speed and grade so you can walk at a comfortable pace.

Strength equipment

By harnessing gravity, body weight, external weight, or tension as a resistance force, these devices help you build strength. As with cardio equipment, styles and prices range widely, from expensive professional equipment most often found in gyms and health clubs to affordable, portable home models.

If you’re just starting out, you can save a fortune by selecting a few basics — comfortable walking shoes plus hand weights or resistance bands or tubing — instead of investing a considerable sum of money in weight lifting machines.

Ankle weights

These are optional for strength exercises like the side leg raise and hip extension. Look for comfortably padded ankle cuffs with pockets designed to hold half-pound or 1-pound weight bars to add as you progress. Ankle weight sets are usually 5 to 10 pounds. A single cuff may suffice, depending on the exercises you intend to do.

Exercise mat

Choose a nonslip, well-padded mat for floor exercises. A thick carpet or towels will do in a pinch.

Hand weights

Depending on your current strength, start with sets of weights as low as 2 pounds and 5 pounds, or 5 pounds and 8 pounds. Add heavier weights as needed. Dumbbells with padded center bars and D-shaped weights are easy to hold. Weighted bands that strap onto wrists and kits that let you screw weights onto a central bar are available, too. Weights are a good place to save cash by checking sports resale stores.

Resistance bands and tubing

Resistance bands or tubing can be used for a full-body strength workout. Attractive features include low cost, light weight, portability, and ease of storage. As with weights, you can measure how challenging the resistance is by how many repetitions of an exercise you can do: if less than eight, resistance is too high; if more than 12, it is too low. Positioning your hands or feet closer together or farther apart on the band or tube before starting an exercise helps vary resistance. Try different positions to learn which make repetitions easier or harder.

Bands. These look like big, wide rubber bands. They come in several levels of resistance from very light to very heavy, designated by color.

Tubing. Look for tubing with padded handles on each end. These also come in several levels of resistance from very light to very heavy, designated by color. Some brands come with a door attachment helpful for anchoring tubing in place when doing certain strength exercises.

What is it about coffee?

What is it about coffee?

Remember when people (and their doctors) used to worry that coffee would harm their hearts, give them ulcers, and make them overly nervous?

In excess, coffee, and more particularly, caffeine, can cause problems. But the fretting about two or three cups a day, or even more, is fading as study results suggestive of health benefits from coffee keep on coming in. Coffee drinking is associated with a lower risk of depression among women, a lower risk of lethal prostate cancer among men, and a lower risk of stroke among men and women. Earlier research also shows possible (it’s not a done deal) protective effects against everything from Parkinson’s disease to diabetes to some types of cancer.

Coffee contains literally a thousand different substances, and some of the lesser lights are thought to be responsible for healthful effects in other parts of the body. Some studies show caffeinated and decaffeinated coffee as having the same effect, which suggests that something else in coffee is involved.

It gets complicated, though. Caffeine and some of these other substances in coffee seem to have their good and bad sides, and coffee’s overall effect may depend on how much they cancel each other out.

Caffeine: Good for the brain, bad for other parts?

Caffeine is the most commonly consumed psychoactive drug in the world, and some of its behavioral effects (such as arousal) may resemble those produced by cocaine, amphetamines, and other stimulants. Coffee consumption accounts for about 75% of the adult intake of caffeine in the United States, although that might be changing among younger adults with the growing popularity of energy drinks.

The caffeine content of coffee varies greatly, depending on the beans, how they’re roasted, and other factors, but the average for an 8-ounce cup is about 100 milligrams (mg). Tea has about half as much caffeine as coffee. Decaffeinated coffee has some caffeine, but the 2 to 4 mg in an 8-ounce cup is a smidgen compared with the caffeinated version. The lethal dose of caffeine is about 10 grams, which is equivalent to the amount of caffeine in 100 cups of coffee.

Caffeine gets absorbed in the stomach and small intestine and then distributed throughout the body, including the brain. The amount circulating in the blood peaks 30 to 45 minutes after it’s ingested and only small amounts are around eight to 10 hours later. In between, the amount circulating declines as caffeine gets metabolized in the liver.

Caffeine probably has multiple targets in the brain, but the main one seems to be adenosine receptors. Adenosine is a brain chemical that dampens brain activity. By hogging adenosine’s receptors, caffeine sets off a chain of events that affects the activity of dopamine, another important brain chemical, and the areas of the brain involved in arousal, pleasure, and thinking. A part of the brain affected by Parkinson’s disease, called the striatum, has many adenosine receptors; by docking on them, caffeine seems to have some protective effects.

Outside the brain, caffeine can be a performance enhancer, boosting the strength of muscle contraction and offsetting some of the physiological and psychological effects of physical exertion. But, especially in the short term, it also has negative effects, which include raising blood pressure, making arteries stiffer, and increasing levels of homocysteine, insulin, and possibly cholesterol.

Chlorogenic acid and other antioxidants

Explanations for the association between coffee consumption and lower rates of heart disease and diabetes often point to chlorogenic acid and other obscure antioxidant substances as the responsible parties. Antioxidants are substances that sop up reactive molecules before they have a chance to harm sensitive tissue like the lining of blood vessels. Some experiments have shown that chlorogenic acid may also inhibit absorption of glucose in the digestive system and even out insulin levels.

Chlorogenic acid might be another coffee ingredient with a split personality. Along with caffeine, it seems to push up levels of homocysteine, an amino acid that has been associated with artery-clogging atherosclerosis.

Vitamins and minerals

Coffee isn’t a great source of vitamins and minerals, but as a plant-based drink, it contains some, and a few that we should be getting more of.

Let’s start with magnesium. A cup of coffee contains about 7 mg, which is a drop in the daily-requirement bucket (420 mg for men, 320 mg for women). But because we don’t eat enough fruit, vegetables, and whole grains, the average American’s intake falls about 100 mg short of the daily goal. A cup of coffee or two can help close that gap a little bit.

Potassium can offset some of the negative consequences of sodium. At about 116 mg per cup, coffee’s contribution toward the 4,700 mg of the potassium that we’re supposed to get daily is a widow’s mite, but it’s something. A cup of coffee also has small amounts of niacin (0.5 mg) and choline (6.2 mg).

A health drink? Not quite.

It is one thing to say that coffee may be good for you; it’s another to say it’s so good for you that drinking it should be recommended. And we’re not there yet.

All of the favorable studies and all of the seemingly healthful ingredients in coffee are good news for coffee drinkers. They can relax and enjoy their habit. And people who don’t drink coffee can find plenty of other things to do to help keep themselves healthy.
