Brief summary: Reduced-exertion high-intensity training (REHIT) is a novel form of exercise known for being non-classical, time-efficient, and effective on different populations. However, REHIT was scarcely tested on sedentary women with mortality risks. The aim of the study is to compare the effects of REHIT versus short moderate-intensity training (SMIT) on functional capacity, resting heart rate (RHR), and activity enjoyment in sedentary young women.

Detailed description: The aim of the study is to compare the effects of reduced-exertion high-intensity training (REHIT) versus short moderate-intensity training (SMIT) on functional capacity, resting heart rate (RHR), and activity enjoyment in sedentary young women. Therefore, sedentary young women will be randomly allocated to either a: i) REHIT group or ii) SMIT group. Both groups will perform an intervention over 6 weeks duration for 10 minutes each session for 2 sessions/week, but with different intensities (REHIT or SMIT). Both forms of exercise will be conducted on a cycle ergometer with the subjects monitored throughout the intervention. Before and after the 3-week intervention, functional capacity (6-minute walking test) and RHR will be measured. Additionally, physical activity enjoyment (Physical Activity Enjoyment Scale) will be assessed after the intervention.

Eligibility criteria: Inclusion Criteria:

* Women.
* Age between 18 and 25 years old.
* Those who score a low physical activity level (\< 600 METS min/week) in the International Physical Activity Questionnaire-short form.

Exclusion Criteria:

* Women who suffer from musculoskeletal.
* Women who suffer from neurological diseases.
* Those who are taking medications.
