Article: Wear workout clothes that give your body a full-range of motion. Pick an outfit that fits well but is not too tight. Usually, loose-fitting comfortable gym clothes work. Choose fabric that wicks away moisture, rather than wearing your old cotton t-shirt and sweats. It's always important to wear closed-toe athletic shoes that fit well. Keep them tied tightly, as loose laces pose a risk of injury. If you're a beginner, start with light dumbbells. Dumbbells weighing 2-5 kg (4.4-11.0 lbs) are best for beginners. Slowly work your way up to heavier dumbbells over the course of several weeks. For example, increase the weight of the dumbbells after using them in your work out two times a week for four weeks. If you are pregnant or have a history of back or joint problems, talk to your doctor about safe lifting limits. It's important to give your body some time to warm up and to limber your joints before burdening them with heavy weights. Try working with lighter dumbbells for 5 to 10 minutes before switching to heavier dumbbells for the remainder of your workout. Poor posture or straining during lifting can cause severe injury. Try to avoid jerking your arms or back (or the dumbbells themselves) when you're lifting. If you're ever unsure of proper form and position, talk to a trainer or staff member at the gym. Ask them to demonstrate the moves or adjust your form while you are exercising. You can also watch instructional videos online for help. If you start to strain or huff and puff, it's time to set the dumbbells down. You're more likely to get injured lifting dumbbells when you're tired because your muscles or joints can give out under the weight. It's safer (and usually more fun!) having a buddy to work out with. Lifting dumbbells is particularly dangerous when you're lifting alone because you don't have anyone to take the weight from you or monitor your physiology if you run into trouble.

What is a summary?
Wear the right clothing. Start with light dumbbells. Warm up before lifting heavy dumbbells. Perfect your form. Quit when you're tired. Work out with a buddy.
