毎日運動する

You can use it as a basic statement. To be polite, change it to 毎日運動します. If you are currently in the habit, use 毎日運動しています. This 'te-iru' form is very common. It sounds more natural for ongoing habits. You can also use it to ask questions. Just add a question mark or か. For example, 毎日運動しますか？ asks if someone exercises daily. It is a great conversation starter.

Use it when discussing your lifestyle. It is perfect for a doctor's visit. You can use it at the gym. It works well when making New Year's resolutions. Use it when texting friends about your fitness goals. It is also great for job interviews. It shows you are organized and disciplined. Use it during small talk about hobbies. Everyone understands the value of health.

Do not use it for specific sports. If you play tennis, say テニスをする. 運動 is a broad, general term. It covers things like jogging or lifting weights. Also, do not use it if you only go once a week. That would be 週に一回 (once a week). Using 毎日 when you don't mean it might make you look like a liar! Avoid it if you are just walking to the fridge. That doesn't count as 運動 in most conversations.

Japan has a deep culture of daily movement. Have you heard of ラジオ体操 (Radio Taiso)? These are morning calisthenics. They started in the 1920s. You can see people in parks doing them. Even some companies start the day with these exercises. It is a national symbol of health. Being 運動不足 (lacking exercise) is a common worry in Japan. There is even a national holiday called 'Health and Sports Day.'

You will often hear 運動不足 (undō busoku). This means you aren't moving enough. Another fun phrase is 三日坊主 (mikka bōzu). This means 'a three-day monk.' It refers to someone who quits a habit quickly. Many people start 毎日運動する but become a 三日坊主. If you are serious, you might say 筋トレする (kin-tore suru). This specifically means weight training. It is very popular with the younger crowd lately.
