Explanation: Both free weights and machine weights can help you increase your strength. Free weights are versatile and inexpensive. They also simulate real-life lifting situations and promote whole-body stabilization. Free weights are generally safe when used with the proper technique. But it may take some practice to get used to lifting with free weights, and it's essential to use proper technique.
Machine weights also can be effective weight training tools, as long as you use machines that adjust to your body dimensions and allow your joints to move through their natural motion paths. Machine weights are generally safe when used with the proper technique. Many people can learn to use them quickly.
