Do you know that free aerobics classes are available all around Bangkok? If you visit Bangkok and want to have some exercise during the trip, you can join the classes. Generally the classes are outdoor and run at the same time. You usually find the classes in the parks or in front of supermarkets.
In the parks
The free aerobics classes are not available in every park in Bangkok. To the best of my knowledge they are available at Lumpini park (the popular one) and Benjasiri Park. In the park usually there are 2 times a day: in the morning (around 6-7 am) and in the evening (around 6-7 pm). Besides, some parks also have yoga classes available.
In front of supermarkets
Maybe it sounds weird for you that there are aerobics classes in front of supermarkets. But, they are available in Bangkok for more than 10 years! And they even have yearly aerobics competition!! The classes in front of the supermarkets such as Tesco Lotus and Big C run only in the evening (around 6 pm), and it becomes a meeting place for many housewives. They usually come to dance and then shop.
You can ask local people about the date and time of free aerobics classes near your place. I am sure they can recommend you at least one. Since Thailand is hot and humid for the whole year, the classes usually are available all year long. So, just dress up and get dancing!
