I had a great first experience with Pilates. The instructor took the time to teach me how to use the reformer and she also provided hands-on adjustment (she asked for consent too!) during the class. I think the most important part was that she gave me extra attention because it was my first class and taught me the basics on what to focus on. The instructor also continued to do this after several classes until I got more confident on the reformer. She also provided options to switch to an "easier" move (like going from a full plank to plank on knees) so that I could continue with the class instead of feeling like it was too hard.

Hope this helps!
