Flat support is very simple and can be practiced anytime and anywhere. There is no requirement for the venue. You can practice at home and in the office when you are free.
Therefore, you can practice several groups in your spare time or in the gym as one of the exercises in physical fitness.
However, flat support is not suitable for slimming. Many people persist in a group for a minute or two, not to mention that you can't persist for an hour. Even if it lasts for an hour, it can only consume about 200 calories.
The ability of flat support is not proved by the time you insist on. Supporting one hour is not the same as supporting two minutes. Just like running, what suits you is the best.
Overweight people who do flat support will put more pressure on their backs because of their overweight abdomen. This kind of people had better lose weight first, and use kneeling posture as flat support to reduce the difficulty. For beginners who never exercise, the initial flat support movement can start from10s,15s, 20s, 30s or any time they can bear, regardless of the support time.
From this point of view, plate support is a deified action, and its function is not so magical.
