The purpose of this pilot randomized clinical trial is to evaluate the willingness, acceptance, adherence and signs of benefits of structured home-based pulmonary rehabilitation (HPR) and supervised pulmonary tele-rehabilitation (PTR) on respiratory symptoms, quality of life, functioning and physical activity in patients with ILD (Interstitial lung disease, Idiopathic pulmonary fibrosis, Sarcoidosis), Bronchiectasis and Asthma who have a clinically assessed need for a pulmonary rehabilitation program. The main questions the project aims to answer are: * Will HPR and PTR appeal to a minimum of 30% of the eligble patients * Be greatly accepted (≥70% of participant complete 70% or more of the planned sessions) by patients agreeing to participate in the study * Will PTR and HPR lead to positive changes in respiratory symptom relief, symptom relief in general and improve or maintain physical functioning larger than usual care Researchers will compare with a comparable control group who gets usual care (scheduled controls and medication but no exercise intervention) to examine the willingness to be randomized and to get an indication on possible health related effects. Participants will be randomly assigned to one of three groups: 1. A structured supervised group-based PTR (exercise twice a week; each session consists of 35 min. evidence-based exercises and 25 min. of patient education) 2. An individual HPR program (self-initiated physical activity) with motivational and professional counseling once a week (10-15min), supported by a tablet screen 3. A control group receiving usual care (CON)
