A user on Quora asked 'how many days should one workout in a week', to which many people responded. One of the most liked comments was where biologist and power lifter Helgi Briem shared, "Once a week is a bare minimum to maintain a base level of strength. It is not enough to make progress but can prevent deterioration, for example while on holiday or during a competition season in a sport. Twice a week produces slow gains for most people and is the minimum effective workout routine. For the vast majority of trainees, three times a week is a sweet spot, providing good progress with adequate recovery."
Celebrity nutritionist Rujuta Diwekar recently shared on social media that the minimum number of days a person should workout in a month is 7 days. She also added that you should have home cooked food at least 22 days a month.
Furthermore, you have to be realistic about your schedule. If you can include only 2 days of workout in a week, make the days count by including an intense training schedule. Five days a week is considered ideal for most, but finally it depends on how much your schedule allows.
