I just had question on force reps or the end of failue set..we always hear about (example))eccentric portion asisted by partner for few extra…or isometric hold at the beginning or end of set …is there any benefit from like doing set failure then doing few concentric only portion of reps..where partner helps on eccentrics portion…i was just wondering i know partials at end …
Definitely a weird idea if hypertrophy is your goal
Not only are there no benefits, it’s actually impossible.
If I understand your question properly, you are talking about your partner helping you during the eccentric portion and stop helping for the concentric portion.
In other words, when you lower the bar, your partner helps you to lighten the load but stop helping during the lifting portion.
Am I understanding you right?
If that is what you mean, it is a physical impossibility.
When you hit failure (as you mention in your question), it means that you cannot lift the weight anymore.
When people hit failure (which is really CONCENTRIC failure) they can still do the eccentric/lowering portion by themselves (because most people are 10-40% stronger eccentrically) BUT they cannot do the concentric portion anymore.
So what you are asking (if I understood you correctly) cannot be done, for the simple fact that after you reach failure on a set, you cannot do more concentric/lifting reps. So having a partner assist you on the portion you can still do by yourself (eccentric) but not helping on the portion you cannot do yourself (concentric) is not possible.
Forced reps have you do the eccentric/lowering portion by yourselt, and your partner help you during the concentric portion (because at that point you cannot lift the weight by yourself anymore). That is a method that’s been around for at least 40 years.

I think you might be confusing eccentric and concentric. Because what you said makes zero sense.
Eccentric is when you lengthen the muscle under tension (e.g. when you lower the bar to your chest on bench press, when you go down on squats, when you bring the bar back up in a lat pulldown, etc.)
Concentric is when the muscle shortens under tension (when you actually lift the weight). For example, when you press the barbell up on bench press, when you stand up on squats, when you pull the bar toward you on rows and pulldowns.
Typically we are 10-40% stronger during the eccentric. Which means that the eccentric portion of the lift is “easier”.
As such, when you hit failure on a lift, you actually have hit CONCENTRIC failure (you can no longer lift the weight) but you likely have not hit ECCENTRIC FAILURE and thus can still do eccentric-only reps or reps when you do the eccentric by yourself and the partners helps during the concentric.

Im sorry.i confused you and i left out important detail…thanks for the reponse ct
(example) bent over rows 6 reps to failure or 1 rir…then rest 20 seconds do concentric only part for few reps an so on …like rest past fashoin…just for like change pace…just thought
Yeah, that’s rest/pause training. Very effective. But typically we do both the concentric and eccentric phases. Doing only the concentric decreases the effectiveness of the rep by around 1/2 to 2/3.
But regular rest/pauses are my favorite hypertrophy method. I just don’t see the logic or benefit in not doing the eccentric.
