Fitness Equipment is any apparatus or device used during physical activity to enhance the strength or conditioning effects of that exercise by providing either fixed or adjustable amounts of resistance, or to otherwise enhance the experience or outcome of an exercise routine.
Activity trackers are available both with and without display.
Certain movements of the user, such as working in the household, cycling, swimming, dancing or rowing can distort the results obtained from activity trackers. In a test conducted by Stiftung Warentest, for example, no product determined the distance of a bike ride, even approximately. Furthermore, the determined values for the human energy transformation were erroneous. With the heart rate, large deviations have been observed at wristlet trackers, and it is recommended for this purpose to use appropriate chest straps.
