"Health is trendy, and we probably have never worked out as much as we do now," Fredrik Koterjahn, head of marketing at the institute, tells news agency TT.
Fitness bracelets are worn around the wrists and monitor a person's efforts as they work out. The bands, for example, can measure how many steps someone takes and how many calories they burn, and also keeps track of how well a person sleeps.
The institute has been coming out with a Christmas Present of the Year since 1988, and over the years, they have included a CD player (1991), a mobile phone (1994), an internet package (1996), and a tablet computer (2010). One criterion for the selection is that it must represent the era in which we live.
