For the kinds of pushing movements you described, you can use it to got to failure on slow, full-range pushups and split squats, without locking out at the top of the movement, to keep the tension going.Well, I think MYO is a technique to get closer to failure, so yes I believe it was the intensity of the exercise. I wouldn't want to use it on something like bench or squats because it would be dangerous. Failure using MYO is a complete meltdown on the last set.
