 Question is from jay main seven a college professor told us that the eccentric part of the lift is the only Important part of the lift because it tears the muscle if someone only repeated the eccentric part of the lift Would they see major gains, or is it a myth? It's just one variable. Yeah, what kind of a professor would say that only important one. Yeah, it is true that the workout Done everybody's like lifting like grandpa. Yeah, so if so for those lifting don't know what that that means So there's there's there's two there's three parts of a lift There's the concentric that's the lifting so if you think if you imagine me doing a curl The concentric is me curling the weight up then there's isometric was which is where you hold it And then eccentric is when you lower the weight So as you're lowering away the muscle is still contracting, but it's doing so in a way that allows it to your existing more Gravitational forces typically yeah It's it's doing it in a way where it's allowing the muscle to to lengthen while contracting that Part of the lift is the most responsible for muscle growth And this has been shown in studies, but used by itself It quickly leads to plateau and it quickly leads to overtraining because it is a very damaging part of the lift now The concentric part of the lift also tells the body to build muscle and it also is what's definitely the one that contributes most to athletic Performance now at Olympic lifters, okay? They do a lot of Concentric only lifting with barely any eccentric. Yeah now squats. I would say they do lots of you know They'll do some eccentric although they lower the weight a lot faster than most lifters Olympic lifters are buffed as hell too though now They're not as big as bodybuilders or power lifters, but there's your evidence right there that the concentric part builds muscle as well Now there's some benefits to to the part of the lift that doesn't cause lots of damage You can do a lot of it so I can increase the volume quite a bit if I'm doing concentric only E-centric there's only so much you'll I don't know if you guys have you guys ever experienced Experimented with like force negatives and yeah doing all night for how long though I mean I did it for a couple weeks and that was plenty. Yeah, you're you're done your Recovery's done. Well, I'm gonna I'm gonna defend the professor a little bit just because sometimes this is He may have been giving a really good message in my opinion and then they just got misconstrued or misunderstood And that's because I've done many talks with trainers where I'm stressing the eccentric part of the exercise Because nobody else is nobody else is and nobody in the gym is if you were if we were to walk in your average gym right now and Look at 90% of the people lifting weights on the floor a majority of those people are not maximizing the benefits that you get from the eccentric movement portion of the exercise And that is slowing the negative down so the negative or the Resisting the weight we tend to just let gravity do it and we just let it drop or fall and then we focus on the concentric part So in hit in defense of him it is just as important So it's not more important than concentric part of the exercise It's just as important want to add on to that like in sports term So to decelerate is a massive part of preventing injuries in like any athletic pursuit So that that second portion of now I have to slow everything down at once rapidly It's usually where people get hurt And so to be able to kind of break that down and focus on that and strengthen that process is valuable But it's one part so you have to consider all the parts and so I just again I Caution myself to just like highlight that specifically as like the answer No, it's all of it. It's definitely not the answer It's probably the most neglected part though sure of an exercise That I think a majority of people could learn from that or take this advice and go apply it to their training I mean, and I've said this on the show before I mean if you've never done this before I I dare you to have a workout where you just change your tempo of 4 2 2 where it's You know 4 seconds on the negative 2 and the isometric hold position and then 2 on the concentric or the positive part of the exercise Just try messing with that tempo. Don't change your workout do the same exercise as you were planning on doing today But just do that in itself and know watch how different you feel totally you're probably going to be a lot weaker Be okay with that but and you're probably gonna get really sore because you're not used to that tempo and that just highlights the benefits of Really putting some more emphasis on the eccentric part of the lift that most people just aren't doing yeah No, you make a good point. I think people don't focus on the muscle. They're working when they lower a weight They don't focus on the tempo It's like am I if I'm low if what I'm pressing in a bench press I'll tend to focus on the pecs But when you lower do you still focus on the pecs or are you just trying to lower the weight right focus on the muscle You're working as you lower the bar of the dumbbell. That's a great That's absolutely build a lot of control too, which is important
