Mirror is expanding its fitness platform with a new line of accessories. To enhance its strength training classes, the interactive home gym is introducing the Mirror Dumbells. The smart weights track reps, correct form, and recommend the ideal weight for each exercise like a personal trainer. They also maintain the same sleek, minimalist aesthetic as the Mirror with a matte chrome finish, zinc faceplates, and glowing blue numbers. They will be available in weights ranging from 1-35 lbs. starting on November 22, along with 1 and 2-pound sets of ankle weights.
