Article: In this article, we consider the box having the lighting fixture or device as the "source" of the power from the circuit breaker.  Two wires enter the source fixture's wire box from the circuit breaker; the black one is called "line" or "hot", and the white wire is neutral (which is grounded at the breaker box). Only the black/line/hot wire is going to be switched. The white/neutral connects directly to the light/device. Note that some jurisdictions now require a neutral wire at each switch location, due to modern changes in switching technology that may require a neutral for a complete circuit, such as "smart switches". For simplicity, this article ignores such a requirement, as these "extra" neutral wires are simply run to each location and are not being switched. This is the "supply" to the switching system.  Remove about 0.25 inches (0.635 cm) of rubber/plastic insulation from each wire. Use pliers to twist the exposed ends of the two black wires together. Complete the connection by screwing a properly sized wire nut onto the joint tightly. Lightly tug on each wire to make sure they are both tightly connected. Wrap the wire nut connection with electrical tape for safety and durability. Repeat this wire connection process at each wire connection. Do not nick or skin the wires anywhere other than at the ends being connected.  This red wire is the one that will supply power to the light after traveling through all of the switches. It is the installer's choice whether to use the red wire or "white" wire (identified with blue or other color) as a traveler. This description uses the red wire as the "switched" wire from the furthest switch. The video uses a different technique to "carry" the white wire, as neutral, through each junction box, all the way to the remote light.
Question: What is a summary of what this article is about?
Look at the wires involved. Connect the black wire coming from the breaker into the fixture location to the black wire going to the first 3-way switch. Connect the white wire coming into the fixture/device box to the white wire on the fixture. Connect the black wire coming from the fixture to a red or white wire that leads out of the box to the first 3-way switch box, and (if using white) identify the white wire with a color marking, such as red electrical tape.
Article: In general, the quicker you move, the harder your body has to work, the more energy it uses, and the more calories you burn. For instance, a moderate-weight person can burn about 70 more calories per hour by increasing their walking speed from 3.5 to 4.5 mph (5.6 to 7.2 km/h). Thus, if you're interested in either burning calories or boosting your athletic potential, you'll want to move faster, rather than slower.  Most health resources define "brisk-paced" walking at about 3.0 mph (4.8 km/h) or greater — if you're unsure of where to start, this is a good benchmark pace.  Note that, in addition to providing better exercise, brisk-paced walking also decreases the amount of time you'll need to take to walk any given distance, freeing up more time for you to do other things with your day! As noted above, pedometers don't just measure steps while walking. Since they record any sort of rhythmic, repetitive, up-and-down motion, they're also useful for recording your steps during any number of other exercise activities. Keep in mind, however, that because your average stride length may differ for these activities, the distance reading you get may not be accurate. Below are just a few other activities for which a pedometer can measure your "steps":  Running Hiking Climbing stairs Jump roping Some pedometers even have options to measure your speed and distance on a bicycle. In general, people lose weight over time if they spend more calories per day than they take in from their food. If walking is your only form of daily exercise, you can use your pedometer to help you stay on track for your weight loss. Since your pedometer can tell you how far you've walked, you can use any online calorie calculator to find how many calories you've burnt based on the distance you walked. Add this to your basal metabolic rate (BMR), the number of calories you burn simply from living, and you'll know approximately how many calories you spent during the day. For instance, a 180 lb (81 kg) person who walks five miles over the course of three hours during the day burns about 720 calories. If this person's BMR is about 1,800 calories (typical for a young 6-foot tall male) they burnt about 2,520 calories during the day, so eating fewer calories than this would cause them to lose weight. Keeping your daily activity at a reasonable level isn't like a New Year's resolution that can be abandoned a few weeks after it's made — it should be a lifelong commitment. People who make a habit of exercising (with or without a pedometer) experience demonstrably longer, healthier lives on average than people who don't. However, these benefits are only the result of sustained, long-term fitness commitments, so try to stay motivated as you use your pedometer to make the task of consistently exercising much easier. Below are just a few ways to get "pumped up" for your fitness goals:  Remind yourself of your goals when you don't feel like exercising. Reward yourself when you achieve minor goals. Get a healthy amount of rest every day. Listen to exciting, captivating music. Watch inspirational movies. Take occasional breaks from your fitness routine. Tell other people about your goals.

Walk at a brisk pace. Use movements besides walking. Use your pedometer to help you count calories. Keep yourself motivated for the long haul.
