It is a great way to stay fit and healthy, and it can also be used to improve sports performance. Weight lifting can be done with free weights, such as dumbbells, barbells and kettlebells, or with weight machines. It is important to use proper form and technique when lifting weights, and to use the right amount of weight for your fitness level. Weights and weight lifting can be used to target specific muscle groups, and can be used in combination with other exercises such as running, stretching and cardio.
