Banana boat is an ab workout.

To preform it, follow the steps below:

  1. Lie on your stomach.
  2. Stretch your arms and legs straight out and slightly up, lifting most of the rest of your body off the floor (this is the "Boat" position).
  3. Turn to your back while keeping your arms and legs elevated (the "Banana" position).
  4. Turn back, keeping yourself above the ground.
  5. Repeat as necessary.

Starting on banana or boat first is simply preference.

It may be noted that when doing this in a group, the usual "One... Two... Three..." is replaced with "Banana... Boat... Banana..."
