毎月運動する

You can use this phrase just as it is. It acts like a simple statement of fact. If you want to be polite, change する to します. You can put it at the end of a sentence. For example, tell your doctor 毎月運動します. Or tell a friend 毎月運動するよ. The よ adds a friendly, informative touch. It’s very flexible and easy to remember.

Use this during a casual chat about your lifestyle. It’s perfect for when someone asks about your hobbies. You might use it when signing up for a gym. It also works well in a health diary or app. If you are making a New Year's resolution, say this. It sounds realistic and achievable for most people. Your friends will appreciate your honesty about your pace.

Don't use this if you exercise every single day. In that case, use 毎日 instead of 毎月. Also, avoid it for one-time events like a marathon. This phrase implies a repeated, monthly rhythm. If you only walked once last year, don't use it. Your Japanese friends might think you're joking. It’s for habits, not random accidents of movement.

Japan takes health very seriously, especially as people get older. You will see many seniors walking in parks every morning. There is a concept called Metabo (metabolic syndrome) that people avoid. Companies often encourage employees to stay active. Exercising isn't just a hobby; it’s seen as a social responsibility. Even simple stretching counts as 運動 in many contexts. It’s about longevity and staying useful to society.

You can swap 毎月 for other time words. Try 毎週 for 'every week' or 毎日 for 'every day'. If you want to be specific, name the sport. You could say 毎月テニスをする for monthly tennis. Another common one is 定期的に運動する for 'regularly exercising'. This sounds a bit more professional or serious. Use ジムに通う if you specifically go to a gym.
