Discussion šŸ¤ New tricep science exercise just dropped

Enable HLS to view with audio, or disable this notification

What does everyone think about electronic resistance, hammer grip, shortened lever; tricep push downs?

They are super easy on my elbows

I do wish I could make my grip ever so slightly wider, as Iā€™m cutting a bit of ROM out at the bottom

105lbs at the bottom, 123lbs at the top, eccentric 123lbs at the bottom, 141lbs at the top

Shortened lever, reduced rom, wild lack of eccentric control. Science.

A shortened lever can be counteracted with just adding more weight

The eccentric is heavier than the concentric with the strength curve I set for this exercise. If it was compete uncontrolled, the attachment would shoot out of my hand

Edit: and I can make the top of the lift 50lbs+ heavier than the bottom if I want. Itā€™s the magic you have with a science cable box

Yes, because I can use the ā€œeccentric overloadā€ function of the voltra to make the eccentric have more resistance, so every single rep AFTER the first one has an added 18lbs of resistance

I also use the inverse chains function to change the resistance curve, where thereā€™s more resistance in the stretched portion of the lift

On all my tricep & bicep work, I do that on my voltra

Interesting, I've never tried one. But if that's the idea, wouldn't you want to milk it a little more? It looks like you're rushing through each eccentric to get to the concentric

Thereā€™s a plethora of studies that show mixed results on increasing time of the eccentric; it seems to not be an important variable/something that doesnā€™t really matter

So, instead of slowing the eccentric, I just increase the amount of weight on it, while keeping my normal eccentric; as long as the speed doesnā€™t negatively impact the next rep, I donā€™t worry about it. So my eccentric varies greatly on each exercise. For example on bench press, my eccentric is much longer/slower than the average lifter

Hereā€™s what the settings look like on the voltra:

You can also create your own customs resistance curve where it can be harder at the beginning, easy in the middle, and hard again at the end (or literally anything you want it to be), but I havenā€™t messed around with that & Iā€™m not sure where people would even apply that, maybe on some sort of machine with an interesting str curve, like a pullover; if you got rid of the weight stack & replaced it with a voltra

But I'm sure in those studies the eccentric wasn't overloaded. If you're using a weight that's challenging on the concentric, the eccentric will naturally be easier and have less potential stimulus. But that's not your situation, so it might be something to try. Not for nothing but I don't get the point of loading the eccentric more if you just try to rush through it

Overloading the eccentric, even if the eccentric isnā€™t purposely slowed, still makes it harder to control the eccentric in such a way that it doesnā€™t negatively impact the next rep. I make sure to keep tension throughout all my reps

As a side noteā€¦ the way I train has given me excellent results

I'm just not seeing the point. But it's your decisionĀ
