Key benefits Targeted core and upper-body training: Designed to work the abdomen, arms, back and shoulders to improve strength and tone. Safer, more comfortable exercise: An elbow support reduces pressure on joints during rollouts and planks, allowing longer, more controlled repetitions. Hands-free guided workouts: Built-in phone holder lets you follow video routines or track time and reps while you train. What it does and how it solves problems Multiplies the effectiveness of bodyweight routines by adding controlled rolling motion for deeper abdominal engagement than static exercises alone. Reduces discomfort and risk of strain with an elbow-support design, so users can focus on form instead of compensating for pain.
