Inclusion Criteria:  diagnosed with type 1 diabetes for more than 12 months using either multiple daily insulin injections or continuous subcutaneous insulin infusion willing and able to perform resistance exercise HbA1c < 10.0%  Exclusion Criteria:  Individuals with HbA1c >9.9% have been excluded as higher HbA1c suggests difficulties in diabetes management, which could be a substantial confounder for blood glucose outcomes. Frequent and unpredictable hypoglycaemia is an exclusion criterion as it would impact the participants' safety during and after exercise. A change in insulin management strategy within two months of the study would exclude a participant as the risk of hypoglycaemia will be higher than normal until they master the new treatment regimen. As the study involves performing physical activity, the following exclusion criteria have been imposed in the interest of participant safety: blood pressure > 144/95, severe peripheral neuropathy, a history of cardiovascular disease, musculoskeletal injuries affecting the ability to perform resistance exercise. Individuals who are treated with medications (other than insulin) that affect glucose metabolism (e.g. atypical antipsychotics, corticosteroids), as these would have an impact on the main outcome measures. Finally, a body mass index >30kg/m2, smoking, and moderate to high alcohol intake (>2 drinks per day) would exclude a possible participant, as each can increase the risk of hypoglycemia.
