Is 30 minutes of biking a day enough exercise?

Hello there, I'm curious about the effectiveness of a daily 30-minute biking routine as a form of exercise. I've heard that regular physical activity is crucial for maintaining good health, but I'm not sure if 30 minutes of cycling each day is sufficient to meet my fitness goals. Could you please elaborate on the potential benefits and limitations of such a routine, and perhaps suggest any additional exercises or adjustments that could enhance its effectiveness? Thank you in advance for your insights.
