A well established entrepreneur with a background as a stuntman and U.S. Marine, William “Bill” Humphries leads Giddy Up Sports and Seven Corp. Online Businesses. As a fitness trainer, Bill Humphries developed the signature Body Attack System. The platform integrates anaerobic and aerobic training, as well as weight training, as a way of achieving superior aesthetic results and weight loss.
Lower intensity and extended in duration, aerobic exercise allows cells to access energy through a preferred oxygen-to-fuel metabolic pathway. Muscles cells contract frequently and with minimal fatigue, and are able to take in sufficient fuel and oxygen.
As exercise grows more intense, aerobic metabolism is no longer enough to supply the body’s energy needs. In conditions when oxygen is not available to the cells, the muscles employ anaerobic metabolism strategies, which result in the release of waste molecules that impact muscle contractions and cause performance fatigue. Once the higher intensity workout shifts down to a slower pace the muscles again transition to an aerobic metabolism footing that allows for the waste molecules’ removal or chemical conversion.
While not as stressful to the joints, muscles, and heart, aerobic exercise does not build exercise performance capacities or endurance to the same degree as anaerobic exercise. Thus, a combination of the two is often recommended for those serious about fitness.
