To prevent injuries when starting a new fitness program, it's important to follow several strategies. Begin with a proper warm-up to prepare the muscles and joints. Gradually increase the intensity and duration of workouts to allow the body time to adapt. Incorporate a variety of exercises to prevent overuse injuries and ensure a balanced approach. Additionally, using proper techniques and equipment, like supportive footwear, is critical. Listening to your body and allowing for adequate recovery time can further minimize the risk of injuries.
