This is why trainjngbto absolute failure is bad. Look at old (dead) man methzer. He could barely move at age 49 due to all that unnecessary heavy duty training he was doing.
Yates also had his number of injuries.
Mark Dugdale tore his chest and quad doing all that hit nonsense.
Its best to leave 1 to 3 reps in the tank before failure.
Even Arnold said training to failure does not mean to exhaustion. It means training until the point when you can no longer do another rep without stopping to take a rest before hand.
