Participants assigned to the intervention group will be asked to perform a personalised exercise programme, undertaken three times a week (with no more than two rest days between sessions) for 12 weeks. Participants will meet the researcher face to face immediately after randomisation. During this meeting, a brief physical assessment will be undertaken and exercise goals will be discussed and agreed with participants. The researcher will then design a personalised exercise programme for each participant using the resources available on the web-based exercise website. The exercise programme prescription and progression will be in line with American Diabetes Association (ADA) and American College of Sports Medicine (ACSM) guidelines (Colberg et al. 2016). The website (www.webbasedphysio.com) will be used to deliver the intervention. This website has been modified, in collaboration with South Asians, to be culturally suitable for people of South Asian backgrounds in terms of content and language (Albalawi et al, under review). The researcher will contact participants every two weeks via telephone to encourage use of the website, ask about progress, and to deal with any technical issues that they might face while using the website. Participants will be advised to contact the researcher to request a change in their programme or if a problem arises. The researcher will make changes remotely and participants will be informed of any changes by phone or email. Participants will be asked to meet the researcher face to face to discuss progression and goals at week 6 (midway). Regardless of groups allocation, all participants will be assessed three times by a blind assessor at baseline (week=0) , after the end of the intervention (week=12) and 8 weeks after the end of the intervention (week=20).
