Primary Outcome Measures

Name	Time	Method
Change in muscle strength	Change from baseline to 12 weeks	Sum of one repetition maximum for the 7 resistance exercise
Change in interstitial glucose time in range	Change from 6 hours before (baseline) to 6 hours after (post-exercise) an exercise training session	Interstitial glucose time in range (3.9-10mmol/L) measured via continuous glucose monitoring

Secondary Outcome Measures

Name	Time	Method
Change in interstitial glucose average	Change from 6 hours before (baseline) to 6 hours after (post-exercise) an exercise training session	Interstitial average glucose measured via continuous glucose monitoring
Change in appendicular skeletal muscle mass	Change from baseline to 12 weeks	Measured by DEXA
Change in whole body fat mass	Change from baseline to 12 weeks	Measured by DEXA
Change in interstitial glucose time in hyperglycaemia	Change from 6 hours before (baseline) to 6 hours after (post-exercise) an exercise training session	Interstitial glucose time in range (\>10mmol/L) measured via continuous glucose monitoring
Change in HbA1c	Change from baseline to 12 weeks	HbA1c concentration
Change in interstitial glucose time in hypoglycaemia	Change from 6 hours before (baseline) to 6 hours after (post-exercise) an exercise training session	Interstitial glucose time in range (\<3.9mmol/L) measured via continuous glucose monitoring
Change in interstitial glucose variability	Change from 6 hours before (baseline) to 6 hours after (post-exercise) an exercise training session	Interstitial glucose variability measured via continuous glucose monitoring
Change in physical function	Change from baseline to 12 weeks	Measured by the short performance physical battery
