286 only requires body weight, as pushups, sit-ups and lunges can be done. Resistance bands are also good options. If more resistance is needed, books, food packages and other objects can all be used as weights for training. Time Exercise duration depends on individual aerobic capacity, but sets of 30 to 50 minutes are recommended. Type Multicomponent exercise programs including aerobic, resistance, flexibility and balance training exercises are recommended 4 . Volume Guidelines recommend at least 150 minutes of aerobic exercise and two resistance training sessions per week. My personal view, considering the risks of immune depletion related to high volume training, is that people who used to exercise before the pandemic should try to keep the same training volume. People who were sedentary should try to adhere to the minimal requirements. Progression It is time to keep fit, not to pursue increases in fitness. Conclusion Government measures that restrict people at home during the COVID-19 pandemic do not need to encourage the wider spread of the sedentarism pandemic. Exercise can fight both public health problems, as long as it is adequately prescribed. Maintaining regular physical activity at home is pivotal for healthy living during and after the COVID-19 global crisis. Author contributions Conception and design of the research: Castro RRT.
