One of the most popular strength training exercises is the curl. This exercise can be done with dumbbells or a barbell. If you don’t feel that you are ready for a light dumbbell then use a book to curl with.

Stand with your legs shoulder length apart and hold the dumbbell at your side with the gripped hand facing forward. Bring the dumbbell up to as close to your shoulder as possible, do it slowly. Now bring it back down again.  Do this 8 to 10 times with each arm.

As with any exercise you should start out slowly and gradually build up the number of repetitions before you go on to a higher weight.
