Meet up with the locals.
Just recently an outdoor gym in Khanom is finished installing and it is free.
Don't watch the locals exercise but join in. From Khanom Golden Beach hotel drive towards 7 Eleven/the City/Crossover (Seeyak), you will see a couple of hundred meters before entering the city on your right hand the outdoor gym.
I went here and what a fun little place it is, there even is a twin twister, arm pulldown machine, bicycle, cross trainer and many more, okay no heart meter or TV but hey Mr. Cow will stare at you like what on earth are you doing………
Have fun!
