evidence that accelerometer-based activity monitors, when worn on the wrist or arm, have the potential to classify many important RT constructs including exercise type and number of repetitions performed. Atlas Wearables (Austin, TX) recently developed the wrist-worn Wristband2, an activity monitor which

( Papastergiou, 2009 ), to name a few. In this study, we focused on wearable digital technologies and, in particular, the use of accelerometers. Notably, the shift toward integrating wearable digital technologies in PE is part of a larger global trend regarding the quantification of health, educational outcomes

). Epidemiologic studies of PA during pregnancy have largely relied on self-report via questionnaires ( Evenson et al., 2012 ) although they are prone to measurement error ( Matthews et al., 2012 ). Device-based measures of PA require the estimation of wear-time, or the amount of time the tracking device was worn

, Sattar, & Lean, 2017 ). In order for individuals to truly attain their step goals, the ability to accurately determine step count becomes important. Wearable technology was rated as the top fitness trend the past two years ( Thompson, 2015 , 2016 ), and this tendency is expected to grow as the use of
