For many Americans, regular exercise is a complicated commitment-one made at the beginning of January that fades out within weeks or months. Busy work schedules,a lack of motivation and unease towards exercising in public all contribute to the discouraging statistics that only around a quarter of adults exercise enough per week.
This month,enterptiser Trent Ward and designer Yves Behar are uncovering their design for a mirror fitness system,Forme. Forme is reflective like a mirror, uses machine learning to heighten workouts, and offers attachments including ankle belts, rope handles and a heart rale monitor. When not in use, the two arms that form the resistance pulley（滑轮）system fold behind it and the display screen disappears, turning Forme into a simple full-length mirror.
Interest in home exercise has particularly increased recently around the world. Home workout apps have seen a significant uptick in downloads,and trendy brands like Peloton have rolled out free virtual workouts for everyone stuck indoors. One French athlete who was kept away from others chose to run an entire marathon on his 23-foot balcony.
But beyond the new restrictions affecting daily workout routines,Ward and Behar are tapping into the same concerns that have made every home workout appealing： the ability to save time and sweat in the privacy of one's home. In an age of personal metrics（衡量标准）-where one can measure their heart rate and sleep cycles with smart watches and train for marathons with AI smart sneakers-Ward and Behar want to improve exercise through machine leaming. Forme evaluates performance and adjusts weights accordingly. Easy access to performance data also makes it easier to track that progress and stay motivated.
Though it's too soon to tell if mirror gyms will be the trend of the late 2010s to 2020s,Behar explained that having a screen in the home can become the basis for more than just fitness,such as shopping or telemedicine.
