Training to failure occasionally can trigger gains in muscle hypertrophy and strength. Using this method too frequently, however, can depress anabolic hormones and lead to overtraining, suppression of the immune system, and overuse injuries. Athletes interested in failure training should periodize their workouts by combining periods of exhaustive and sub maximal workouts to promote adaptive changes and allow recovery. While failure training has a machjo appeal., it prolongs recovery time and interferes with other activities, such as learning sports skills. Failure training can also severely injure muscle cells, creating a condition called rhabdomyolysis. Myoglobin from muscle cells leaks into the bloodstream and can cause kidney failure. While sometimes useful, training to failure excessively is inefficient, inefective, and protentially dangerous.
