Primary Muscle: Abs
Equipment: Bodyweight
Level: Intermediate
Purpose: To target the upper abs.
Execution: Lay flat on a decline bench with your legs locked under the pads. Place your hands by your ears but avoid holding your neck. Crunch up, lifting your shoulder blades off the floor while curling your spine. Squeeze your abs as you raise yourself, especially at the top of each rep, before slowly lowering yourself to the start position. Be sure to fully exhale your breath as you crunch up and inhale as you lower yourself.
