my waist, my butt, my legs, all so stiff i am like doing machine dance in the pool instead of wave like motion.
how do you guys practice that wave-like moving body?

Learning swimming at outdoor swimming pool and getting sunburn. Can we apply waterproof sunblock before going in to the swimming pool? What kind of waterproof sunblock is recommended ? Thank you
