Activity tracker maker Fitbit Inc has said that young adults in the United States are lagging behind older age groups in returning to the same number of steps as before the coronavirus outbreak, Reuters reported.

Women and men under 29 years old took fewer steps in June than the same period a year ago, according to data aggregated from Fitbit users, as the novel coronavirus prompted people to stay at home.

People over 30 years old were closer to last year's levels, and women ages 50 years old to 64 years old even took more steps in mid-June than a year ago.
