Doing Pilates twice or three times a week is usually enough to observe progress over time, depending on your training goals. Exercise professionals agree that three times a week is ideal, but for those attending a reforming Pilates class, two or three days a week should be sufficient. Research has revealed that twice-weekly sessions can have a positive effect on changes in body composition. Significant differences in the initial and final measurements of skin folds and in body fat percentages were observed.
Additionally, 72% of the participants in the once-a-week group experienced complete improvement in their symptoms after six weeks, and 30% reported improvement after the first week. In conclusion, twice a week is enough to achieve Pilates results. However, if you want to maximize your progress, it's recommended to attend Pilates classes three times a week.
