What is the Plank Timer with Form Check?
Most plank timers just count down. This one watches your body through the camera, measures how straight your line is from shoulders to heels, and times how long you hold with good form. When your hips drop it says 'Hips too low', and if they rise it says 'Hips too high'.
It works from the side, front or diagonal because it measures hip height in real 3D. It announces your time at 10, 20 and 30 seconds and every minute, tracks the percentage of good form and remembers your best clean streak.
