Breathhold Walking Anders Olsson uses this technique to increase carbon dioxide and, thus, increase circulation in his body. It’s not much fun, but the benefits, Olsson told me, are many. Go to a grassy park, beach, or anywhere else where the ground is soft. Exhale all the breath, then walk slowly, counting each step. Once you feel a powerful sense of air hunger, stop counting and take a few very calm breaths through the nose while still walking. Breathe normally for at least a minute, then repeat the sequence.
