Sure, we can all apply going to failure, and beyond (forced reps, drop sets for example), for results. It is another protocol of training. More of a shock and awe approach, but with a short period of limited sets and more spaced out workouts. Do not want to make going to failure a core part of any or all workout. As, every set of every exercise. That becomes counterproductive as far as recovery and future progress goes.
If trying to go to the point of failure (momentary, complete and negative) than have it as the last set, or two, of a muscle group exercise. And maybe once or twice workouts every third or forth week.
Guy's who do BB curls will do something like that, going to momentary failure (can not budge the bar at all) than have a workout partner(s) help lift the bar up to the top position of the curl. Than the curler will preform negative reps by slowly, and in control, lower the bar back down to the bottom position. Have taxed the positive phase of the curl, and with the negatives you will be taxing the negative portion of the curl. The negative action of most any exercise is much stronger than the positive. Your getting almost complete exhaustion of the muscle that way. Can use a DB, one arm at a time, either standing or sitting (cont. curl). Benches, chins, squats, etc also work well with this training. Good Luck.
