Article: Because you don't have a weight machine to help you maintain the proper form, you have to pay careful attention to how you lift the weight. "  If you can't lift and lower the weight slowly and smoothly, choose a lighter weight. If you can't complete the last couple of repetitions, you could find yourself trapped under a barbell or straining your muscles in an attempt to maintain control. A spotter will help you lift the weight safely so you can finish your set. You can often ask another member to spot you in return for being his or her spotter. Make sure you have the same weight on each side and that they're secured with collars. Both dumbbells and plates are racked in order of weight.

Article: Although this is important for everyone's dental health, tooth brushing is especially important for keeping a smoker's teeth white. Brush your teeth twice to three times a day, being sure to brush for at least two minutes each time. Use a whitening toothpaste if you would like to get an extra level of whitening action.  Smokers tend to have poorer oral health and a higher risk of periodontal disease, so it's important to focus on keeping your mouth healthy. In addition to reducing the risk of problems in your mouth, like gum disease, brushing will whiten your smile. Try brushing right after you smoke. This will remove the tar and other chemicals deposited on the teeth quickly instead of letting them set it. There are special toothpastes for smokers. These toothpastes contain more abrasive ingredients, such as baking soda or alumina than normal toothpastes. This helps to get at the tar and nicotine embedded in the teeth. Because these toothpastes have additional abrasive, they can wear down your enamel faster. If you are concerned about your enamel wearing down, consider using smoker's toothpaste some of the time and regular toothpaste the rest of the time. There are specialty mouthwash products that are made to reduce the amount of tar and chemicals in your mouth after smoking. They are made to be used after each time you smoke. Using a normal mouthwash won't keep your teeth white but it will improve your overall oral health. Use a regular mouthwash even if you can't get your hands on an anti-tar mouthwash. Just be sure to pick a therapeutic mouthwash that actually fights gingivitis and freshens your breath at the same time, as opposed to a mouthwash that just freshens your breath. You should be able to tell the difference because therapeutic mouthwashes include fluoride and antimicrobial agents. It's important to floss your teeth before you sleep or after brushing. In addition to improving your general oral health, it will also help to remove nicotine and tar from your teeth. This will decrease the risk of staining in the areas between teeth.  Pick whatever type of floss you like. The type of floss matters less than how you use it to clean between your teeth.  Floss your teeth once a day. It does not matter when you do it, just do it. If you are a smoker you should schedule dentist appointments more often than if you didn't smoke. Consult with your dentist about how often he or she thinks you should come in.  Your dentist will give your teeth a thorough cleaning during your regular visit, which should take away any light staining and lessen any deep staining. If you are interested, your dentist can also give you information about smoking cessation, including giving you information on the ill effects smoking has on oral health.

Article: Keep the person’s head tilted back. Pinch the person’s nostrils closed, using your thumb and forefinger. Cover the person’s mouth tightly with your mouth. Keeping a tight seal over the person’s mouth, slowly give two breaths (“rescue breaths”). Pause between each breath. Watch for the victim's chest to rise. If the chest does not rise, reopen the airway, check your seal on his mouth/nose and breathe harder. Turn the head slightly or tilt it back slightly more, then again try giving two breaths with a pause between. Begin chest compressions if the object is removed but the victim no longer has a pulse. To perform chest compressions:  Ensure that the person is lying flat on the floor on a hard surface. Place the heel of one of your hands on the person’s breastbone, right between her nipples. Place the heel of your second hand on top of the first. Lean directly over your hands. Start performing compressions. Push down with your hands at least 2 inches into the person’s chest, then let the chest rise completely. You will have to push hard and fast. Count out 30 quick chest compressions. After 30 chest compressions, open the person's mouth again and look for a dislodged object. Pull it out if you can. Attempt a quick sweep again if no object is immediately seen. If you do not see the object, give two rescue breaths again, with a one second pause between each. If the person’s chest is still not rising and falling, keep repeating the cycle of 30 chest compressions, then two rescue breaths, until emergency medical assistance arrives. If another person is with you, switch off with him every two cycles. CPR is exhausting. Do not attempt to continue CPR if you are too tired. Improper CPR is not helpful to the patient.

Prepare for rescue breathing. Begin breathing. Reposition the head if the person does not begin breathing. Start performing compressions. Stop and check to see if you can see the object causing the blockage. Continue the cycle until help arrives, if the person does not resume breathing.
