Hi lovely,

Reformer Pilates is a great workout! But we’ve had some women tell us that they have bulked up from reformer pilates. Some workouts do include lots of squats and lunges which build muscle in your quads and can make your legs bigger and more muscly. This depends on your teacher and the style of reformer pilates that they teach. Again, if your goal is to slim down your legs, I would try a few different teachers and classes to find one that suits you best. If you are still having issues with reformer pilates, I would try regular floor-based pilates instead. :)
