This varies from person to person, just because of need. Everyone's resilience is different, and the interval is different. Generally, they practice every 1 day. If they do a lot of exercise, they can practice every 2-3 days. If you just want to keep fit, I suggest you take a rest for 2-3 days. If you just want to keep fit and build some muscles, you can do it once a day/kloc-0. If you want to engage in bodybuilding, you can practice it twice a day! Chest muscles: dumbbell flat bench press, dumbbell flying bird. Abdominal muscles, abdomen, and anti-abdomen (sit-ups without abdomen are effective). Practice any movement, do it slowly and recover slowly, so that the muscles can be fully congested and expanded, so that the effect is obvious. You can practice a muscle group every other day, such as chest muscle, deltoid muscle and back muscle on Monday, abdominal muscle, lower limb muscle, biceps brachii and triceps brachii on Wednesday, Friday is the same as Monday, and so on.

When you are tired, you can extend your rest day to avoid fatigue injury. Health first!
