February 6, 2021 — For some time now, speculation about the impact of COVID-19 on obesity risk in children has been plentiful. It makes sense.

Will Home Fitness Surge Past the Pandemic?

January 9, 2021 — We seem to be living in boom times for home fitness – at least for the folks selling it. In 2019, people wondered if Peloton would be a flash in the pan. After a 2019 IPO at 29 dollars per share, its stock price dropped by more than 30 percent in early 2020. But that […]
