Generally speaking, it is more appropriate for office workers to exercise for 30 minutes to 1 hour every day. This time does not need to be completed at one time, and it can be practiced in two or three times. The length of fitness time also depends on the individual's physical condition, goals and schedule. If time is tight, you can choose high-intensity short-term training, such as HIIT. At the same time, we also need to pay attention to diet, sleep and other aspects to comprehensively maintain good health.
