I imagine a horizontal bar, like when using the pump, but with two small indicators moving towards the center of the screen. A huge green field is centered on and occupies the middle of the bar, and if the player hits the confirmation button while the indicators are over it they manage to get unstuck. Too early, or let the indicators touch in the middle, and they fail. But there's like a second and a half, easily handled.
Of course, those huge green chunks? Easily hit? Is it just your imagination, or are they getting thinner? The timing more precise as your BMI goes up?
