Sitting for longer periods of time has been proven to be dangerous to one's health. Unfortunately, that is exactly what many of us are doing as we continue working at home as a result of the COVID-19 coronavirus pandemic. And with gyms across the country having closed their doors as part of social distancing measures to slow the virus' spread, it seems that we may have little time and space for much needed physical exercises while on home quarantine.

The good news is that now is the best time for you to buy desk exercise machines that are currently available online. These machines help you shed excess body weight and tone your muscles even while you are sitting and telecommuting within the confines of your household. For a more active lifestyle while working at home, here are 7 of the best desk exercise machines to help you stay in shape in the face of the coronavirus threat:
