These extra workouts are intended to raise the lagging muscle groups . While working almost nonstop, you will also raise your general physical preparedness (GPP), something else that is often overlooked. For sports many drills can be used as well. Agility, flexibility, and dexterity can also be improved. These are workouts that do not necessarily serve to directly increase the bio-motor qualities of our sports but instead increase our work capacity, aid recovery and induce hormone release. By performing extra workouts we better equip our bodies to perform those workouts that DO serve to increase the required bio-motor qualities and hence make greater progress in the long term. Benefits are accrued from extra workouts because increased blood flow aids recovery, lactic acid is associated with release of growth hormone, glucose disposal and nutrient uptake are greater following extra workouts and increased work capacity allows the body to accept and recover from greater training loads in the main workouts. If recovery ability is in abundance extra workouts can be performed more intensely as a mean to bring up weak points or build muscle tissue.
