Heyhey, yeah definitely have a read of the links Mick provided, it's a great method, and I use it alot.
It's essentially a rest-pause technique, but different reasoning and way of going about it than usual rest-pause. You're only going close to failure, not complete failure, and essentially doing an 'extended' set at that high activation level, and extending that out so more reps are at that level. So it therefore has more 'effective' reps. Rather than having to do a set, rest, then do a whole new set to reach those end reps, it recreates those last-few-reps-of-the-sets over and over.
Definitely not for beginners at all, an advanced technique and you have to have good solid exercise technique and experience with going to failure or near failure to know what it feels like and to be very in tune with your body's exertion and fatigue levels.
It definitely saves time in your workout too.
Would actually love to hear Bryan's thought on myoreps and the scientific validity in terms of hypertrophy benefits. It clearly is a method that works, and has worked time and time again with many many people, but why that is intrigues me... unless it's moreso related to it still adhering to general HST principles so it's bound to work, but the question is why do straight sets when you can do myoreps and vice versa... Borge is the man, and I really resonate a lot with his training thoughts, and he definitely knows his stuff, incredibly knowledgeable.
