Pilates lowered long-term blood sugar markers in type 2 diabetes

Exercise is a cornerstone of managing type 2 diabetes, but most of the evidence centres on aerobic training and conventional resistance work. Pilates — low-impact, controlled movement — is popular with people who find higher-intensity exercise difficult or intimidating, yet whether it actually improves blood glucose control has been unclear. HbA1c is the standard marker of longer-term glycaemic control, so establishing whether a gentler modality can genuinely shift it matters for anyone weighing up their exercise options. This review set out to pool the randomised evidence and put a number on it.

The researchers searched eleven databases up to April 2025 for randomised controlled trials comparing Pilates, of any type, against standard diabetes care in people diagnosed with type 2 diabetes. From 368 studies initially identified, eight met the inclusion criteria for the systematic review and seven contributed data to the meta-analysis. The two outcomes were glycated haemoglobin (HbA1c) and fasting blood sugar, and effects were pooled as mean differences between the Pilates and standard-care groups.

Pilates significantly improved both glycaemic markers relative to standard care. Across 275 participants, HbA1c fell by 0.96% (95% confidence interval −1.39 to −0.52). Fasting blood sugar, pooled across 231 participants, dropped by 23.98 mg/dL (95% confidence interval −35.89 to −12.07). Both results reached statistical significance at p < .001. On this basis the authors conclude that Pilates may be an effective intervention for reducing HbA1c and fasting blood sugar in people with type 2 diabetes.

Structured exercise is already established as beneficial for glycaemic control, and this analysis extends the evidence base to Pilates specifically — a modality that had not previously been quantitatively synthesised for these outcomes. The picture it paints is encouraging but not definitive: the pooled samples are small, at under 300 participants for the primary outcome, and the included trials used varying types of Pilates. Open questions include the optimal frequency, duration and format, how Pilates compares head-to-head with aerobic or resistance training, and whether the effect holds up in larger and more diverse populations.

If you have type 2 diabetes, or are supporting someone who does, this is a reason to think of Pilates as a genuine metabolic intervention rather than merely gentle stretching. The pooled trials suggest meaningful movement in both HbA1c and fasting glucose compared with standard care alone. It does not replace prescribed management, and the evidence base remains small, but it broadens the menu of exercise styles with randomised-trial support for blood glucose control — useful for anyone who prefers, or is limited to, low-impact movement.
