Do a few light stretches as well. The main portion of the workout is a series of exercises called repetitions. Either one is fine-or try both. Weight machines position your body specifically to work one muscle or muscle group. Machines are considered the most foolproof method for beginners, almost guaranteeing that you use the correct form, which helps prevent injuries.
Free weights are hand-held weights such as barbells and dumbbells.
If you think about it, a machine keeps the weight in balance, while it's up to you to stabilize a barbell while you're lifting it. That means you use more muscles and get a more thorough workout. A good weight-lifting plan will usually incorporate both weight machines and free weights. It depends on your goals, but the key word for a safe and beneficial weight-training program is moderation. The most common mistake that beginners make is trying to lift too much too soon.
