It depends not only on the coach, but also on the members to see if there is any difficulty grading in the gym courses. If the course is graded, the time will be longer, and the new and old members will take classes together, and the coach can only take care of the majority. Therefore, gym courses must be divided into elementary, intermediate and advanced. At present, the best gym in Baoan District of Shenzhen is aerobic fitness, which is located on the fourth floor of Xinyijia Supermarket, Park, Zone 22, Baoan District.
