Systematic sclerosis (SSc) is a potentially severe disease characterized by various visceral involvements including lung. The investigators hypothesize that a respiratory rehabilitation program specifically designed for people with systematic sclerosis with early lung disease could help to decrease respiratory deficiencies, improve aerobic capacity and prevent activity limitations and participation restrictions. Before testing the effectiveness of such a program, a pilot study is needed to assess its feasibility and optimize its content. Participants will have 1 supervised session in the outpatient rehabilitation department. Each patient will then perform the home personalized exercises program for 3 months. The feasibility of the program will be assessed at 3 months using patients' adherence to the program (assessed by the number of lost to follow-up, the number of questionnaires not completed, the amount of aerobic activity and the amount of home personalized exercises, treatment burden, adverse effects and quality of life.
