So, first of all, all this stuff can be fairly normal as a beginner. You’re not going to improve overnight, so keep practicing. Also, everyone’s body is different. No one’s is truly perfect. DO NOT GIVE UP. Don’t quit. If you really feel that your class isn’t the best for you, talk to your instructor. If you’re still unsure, talk to the owner of the studio. Finally, take a look into other studios. I wouldn’t recommend the last one for a while, though.
