Lie on your back with your hands planted beside your ears, fingers pointing toward your feet (or set up for your tier's variation). Press through hands and feet, lifting your hips and chest toward the ceiling into the bridge for your tier. Hold, and keep breathing.

Declare your tier before starting. The timer starts when the declared position is reached and stops when any part of it breaks. Arms straight where the tier requires it. Longest hold at your tier wins; a higher tier always outranks a lower one.
