A popular option is the tonal mirror. It costs around $3,000, with additional smart accessories for an additional $450. After a quick strength assessment, it uses your results to adjust sets based on your goals and current limits, and the mirror automatically adjusts in one-pound increments as you progress.
According to the Tonal website, the mirror also offers recommended workouts tailored to your goals. Some training categories include athletic performance, pre and postpartum, boxing and barre. Streaming workouts are also available but require a $49 per month subscription.
