Thirty minutes? Training (30? 0 Hugh)
No warm-up and stretching.
Standing all the way, no squatting, no jumping, fancy leg lifts, knees and elbows. There is no intermittent exercise, so the heart rate has never dropped. The action looks ordinary, but it tests the control and balance. It's not easy to make a standard!
Therefore, although this set is not very expensive, it has been sweating wildly. There will be quite a gasp at first, and then it will gradually return to normal. It's good to do it on an empty stomach, but not amazing! The difficulty is medium and low, suitable for beginners.
