There is No Off-Season > Training to Failure

• What causes Failure?

  Gradual fatigue of target muscle fibers. All muscle fibers don't come into play at once. You use some, they become fatigued, and the body recruits new ones to take their place. Until the body is unable to contract anymore.

• Process of Oxidation

  Used in production of muscle contraction. Oxidation requires a fuel source (ATP found in muscle) and oxygen. When fuel or oxygen is depleted, muscle fibers can't contract until replenished during rest.

• Lactic Acid

  Build up of waste products resulting from the release of energy due to muscular contraction. The burning sensation felt in the muscle while pumping out reps is due to accumulation of this lactic acid.
