Brief summary
Contemporary cardiopulmonary rehabilitation programs often utilize cycling ergometer, involving one-on-one heart rate monitoring by physiotherapists to ensure that patients reach the target training intensity during training sessions. However, the process is frequently described as monotonous and boring, resulting in early fatigue of therapists and patients as well as poor compliance, leading to undertraining and suboptimal outcomes. This study aims to test the feasibility of the Intelligent Cardiopulmonary Training System (ICRS) and a novel indicator of measuring the adherence to training intensity. The ICRS was developed with the idea to provide machine-based supervision on the user's heart rate during training. It provides moderate-intensity continuous training with a cycling ergometer. This system automatically adjusts the paddling resistance according to the user's real-time heart rate, and helps to improve the user's adherence to pre-determined training intensity without trainer's watch. The automation of intensity adjustment has its potential for conditions in which supervision is not feasible.
Interventions
Participants are required to wear a wristband heart rate monitor and exercise on a cycling ergometer-based ICRS for 30 minutes (5 minute of warm-up, 20 minutes of training followed by 5 minutes of cooldown). The target intensity for the 20-min training period is set at 60%\ 80% HRR determined in the pretest of cardiopulmonary exercise test.

Intervention model description
A small group of healthy subjects with sedentary lifestyle is recruited to validate the ICRS. They receive training with ICRS three sessions a week, for a total of 12 sessions. The outcome assessments are performed before and after the training.
Eligibility
Inclusion criteria
1\. Sedentary healthy people
Exclusion criteria
* Patients whose heart rate can not be used as the indicator of training intensity (eg, ar-rhythmia, atrial fibrillation, beta-blockers users) * With any reason that the patient is not suitable to undergo * Patients who are unable to do cycling due to musculoskeletal problems * Patients who can not follow the instruction of trainers due to cognitive or emotional-problems. * Patients whose medical condition is not unstable.
