.I am just proposing that the training philosophies Black Label No of Bodybuilders and Marathoners are not the path to an optimum level of fitness where all of the physical skills of cardiorespiratory endurance, strength, flexibility, power, speed, coordination, agility, balance, accuracy and toughness are improved... Whether you adhere to the philosophy of each group alone or in combination.I know this goes against most physical training protocols used in commercial gyms around the world that adhere to the cardio body building combination as the training methods of choice.
