A typical duration for a warm-up before exercise is about 5 to 10 minutes. This timeframe is usually sufficient to gradually elevate heart rate and increase muscle temperature. A warm-up should consist of dynamic movements that mimic the activity to be performed, preparing the body for the specific demands of the workout. This helps reduce the risk of injury and enhances performance by improving flexibility and range of motion. Ultimately, a well-timed warm-up can significantly contribute to a safer and more effective exercise session.
