INPUT ARTICLE: Article: These key muscles provide a strong base for your upper body, helping ensure good form and stability when lifting. They include: Deltoids: These muscles from a triangle pointing down from your shoulder, and help rotate and lift your arms. Trapezoids: Coming down from both sides of your neck and forming a point in the middle of your spine, these are essential for shrugging motions, twists, and pulling something down towards you. Lats: Found on your ribs and back, your lats help keep your body stable and spine aligned. With your arm hanging by your side, grab a comfortable dumbbell (one-handed weight). Keeping your arm straight and elbow locked at 90-degrees, raise the weight up so that your arm is straight in front of you. Do not keep going up your arm should be at a 90-degree angle to your body. You will look a little like an old cartoon robot, with bent arms and a stiff back. Aim for 3-5 sets of 10-15 reps. Variations: Mix in sideways deltoid raises. Bend your elbows at 90-degree angles so that the weights are in front of your body, roughly stomach level. Raise your elbows up and to the sides, as if they were wings, and then slowly return your arms to your sides. Stand with your feet shoulder-width apart. Hold a barbell at neck height with both hands shoulder-length apart on the bar. Push the weight straight up above your head, ending with your arms completely extended, then slowly return it below your chin. Do 3-4 sets of 8 reps. Keep your back straight and your feet solid to keep your balance. Never bend your back, contort your arms, or lean either way to get the weight up -- you need to be able to get the bar up in one fluid motion. If you feel tired, stop. This exercise can be dangerous if you drop the weight above your head. Military press is also a great exercise for your back and triceps. Hold a barbell (long, two-handed weight) near your thighs with your arms hanging straight down. Lift the weight 2-3 inches by raising your shoulders, then slowly lower them back down. Repeat for 3-4 sets of 20-30 reps, as shrugs work best as a high-volume exercise. Lie face-down on a bench with your arms hanging freely in front of you. With a dumbbell in each hand, pull the weights up until your arms are bent 90 degrees, as if you were rowing a boat with both hands. Many gyms have rowing machines as well that let you perform this sitting down by pulling on a weighted cable. Keep your back straight and bend from the waist to row, not the lower spine. Pull-ups are fantastic full-body workouts, but they hinge on having a strong back. The wider your grip, the more intense the exercise will be for your back muscles. Grab an overhead bar so that your feet cannot touch the floor. Pull your chin up over the bar, then lower yourself so that your arms are straight. Repeat for as many reps as you can. Many gyms have assisted pull-up machines that remove some of your weight, making your push-ups easier. You might encounter reverse pull-up machineswhere your pull a bar down to chest height instead of pulling yourself up. This is a great way to get stronger, but know that the closer you put your hands together the more this becomes a tricep exercise.

SUMMARY: Know the essential muscles in your shoulder and back. Do deltoid raises. Do military presses. Do shoulder shrugs to build shoulder and back muscles at the same time. Do rows to build back muscles. Do pull-ups to build your back along with your arms.

In one sentence, describe what the following article is about: If you want to make the investment, buy an electric trimmer specifically designed for eyebrows. Otherwise, if you have a beard or mustache trimmer, use this. It's not a good idea to use hair clippers, as the blade is too wide and won't give you much precision. Only use an electric trimmer if you have bushy eyebrows that need to be thinned and shortened. You must use caution with an electric trimmer because there is a large margin of error, and you don't want to remove too much of your eyebrow. A nose trimmer also works well because of the narrow blade width. The goal of trimming with an electric trimmer is remove length and bulk, so comb the hairs up and out, away from the skin, tilting the teeth away from the face at a 45-degree angle. Hold the comb in place when the desired length to be cut is in the teeth of the comb. It is better to trim a little bit and repeat than to trim too much on your first pass. Only allow about 1 mm of hair to stick up out of the comb so that you only cut 1 mm of hair at a time. Repeat this later if you need to remove more. Turn the trimmer on and press it to the comb near the outer edge of your eyebrow. Gently and carefully move the trimmer along the comb, trimming the hairs as you go. It is important to keep both hands steady so you don't remove more hair than you intend to.
Summary: Choose an eyebrow or beard and mustache trimmer. Comb the eyebrow hairs outward with the provided fine-tooth comb. Run the electric trimmer along the length of the comb.

All chemicals, including substances like window cleaner or antibacterial cleaner, have the ability to remove the protective coating on the screen, which will inevitably result in a shorter life for your device. Never use a substance other than water to clean the screen. Don't use cleaners meant for LCD screens, either. Those are meant for a different type of material, and they're harmful to iPhone and iPod Touch screens. Even natural substances like vinegar and lemon juice are too abrasive for cleaning the screen of an iPhone or iPod screen. Water is fine to use in very small amounts, but it should never be directly poured or dripped on the screen. Always use a microfiber cloth to transfer a little moisture to the screen, and make sure to wipe it off right away with a dry cloth. Submerging an iPhone or iPod Touch in water is a sure way to ruin it. Don't try to soak it in an effort to remove a stubborn stain. If you accidentally get too much water on the screen, examine the user manual that came with your device to determine what steps you can take to fix it. Using an abrasive towel, or even a paper towel or napkin, can scratch and damage the screen of an iPhone or iPod Touch. If you lost the cloth that came with your device, you can pick up a new one at a computer store, or use a cloth meant for cleaning the lenses on glasses. If your device's screen has been damaged by a stain that won't wipe away, check out the warranty that came with it to determine whether you can take it in to have it cleaned or repaired. Trying to do so yourself may result in further damage.

One-sentence summary -- Don't use household cleaners to clean your iPhone or iPod Touch screen. Don't soak the device in water. Always use a lint-free cloth. Be willing to get your device professionally cleaned.
