Tricep Pushdowns to Failure! Putting our dynutrition athlete iamthomaspowell, through a set of tricep pushdowns to failure. The first exercise for triceps and fourth of the day after obliterating the delts! I recommend you bring the bar in towards your hips and squeeze the triceps at the peak contraction with a controlled negative. m13gym #MrOlympia #Bodybuilding #Gym #Training #Triceps
