It really depends on what you want to achieve. If it is to increase muscles, multiple groups are better. If it is to reduce fat, multiple groups are better. Of course, if you are a novice, it is better to suggest fewer times and more groups, so as to avoid being injured by excessive load. However, it is ok to exercise in small groups or groups, depending on what you want to achieve. And you can adjust each interval training mode according to your own situation. This will have a better effect on your exercise.

Moreover, the laws in different exercise modes are also different, that is, each exercise mode has its own amount of exercise within a suitable range, that is, the number and frequency of exercise groups. For example, push-ups and dumbbells, the number of push-ups will basically be redundant dumbbells, and the number of groups is basically the same as dumbbells. Of course, this is just a statement. The most important thing in exercise is to look at the individual. Everyone's situation is different. Some people have better physical fitness and may train more. Some people with weak constitution may have to take their time and train less.

Each exercise method and the number of combined movements play different roles. What kind of exercise can exercise a certain muscle or what kind of exercise, different combination actions have different effects, some are muscle gain, some are weight loss, and some are explosive. This is completely different. However, it is best to finish each group at the same time. This interval has a certain saying. Every exercise method has its interval. Of course, when we exercise, we'd better find a fitness instructor. They will be more professional.

The fitness instructor will formulate training methods according to your situation and your requirements, and will make some changes slowly according to your physical changes.
