I did not renew my NASM CPT for the same reason. Most of the potential CEUs I saw available were expensive NASM courses that didn't seem like they would benefit my training clients extensively. It would be nice if NASM offered something like, "CPT Renewal Course," where they do quick refreshers and cover new studies or theories that have come out over the past 2 years. I'm all for continuing my education, I just don't think I should have to spend a lot of money to learn information that I will rarely use to say I'm doing so.

Great video. I personally believe that the average person needs to worry about things like metabolism, hormones, T-Levels at all. In most cases, the actual reason people don't make progress is something as simple as exercise selection, lack of training intensity, no workout plan, unhealthy diet and lifestyle. Metabolism is rarely the case. Mostly people use this as an excuse. "I just have low metabolism." For men it is: "My Testosterone is low. I reached my genetic potential just after 2 years of training and now it's time to hop on the gear." What's surprising is that I got a lumen ad at the end of this video 😂

This was a very empowering video!! To me, it's not really the end of the world if I naturally gain weight no matter what I do, but I definitely thought that process was going to begin once I reach 30 in a few years. So it's kind of nice to know that might not happen so long as I can keep up with my current level of physical activity!! It's too bad that NASM seems to have sold out in this way, though :/

I am currently taking the NASM CPT program and it really does upset me how, outside of that program, they seem to not put in the same amount of care. I hope they change things in the future because it is embarrassing being associated with a company that is doing things like this. Thank you for bringing it to everyone’s attention!

Well thank gawd, I still have 5 years before I slow :) I keep being told I'm going "downhill" already and that makes one think "why bother trying". I always thought it depends on at what age each person starts to lose lean muscle tone from aging and 60+ if one does reasonable amount of exercise you would still lose it naturally as everything in your body starts shrinking. In your 50's tho one is still pretty active, unless injured or disabled, and most have good muscle still if they keep healthy/fit. Thanks so much for this new info. Yes drop them and get the other certification.

What about hormones though? Your age definitely affects hormones and hormones can affect your weight. I'm not sure you can make the leap to say hormones affect your metabolism exactly. But it seems many people complaining about a "slow metabolism" are really complaining about weight gain...which can be affected by hormones...which are affected by age. It gets very confusing!

Hi Justina! I was wondering your thoughts on a hypothesis of mine. When I first heard about the new science of metabolism saying that it is stable between ages 30 and 60 I started thinking about other possible explanations for why people often gain fat during those years. I know the one you put forth in this video is that it's due to lifestyle changes but I was wondering if you thought it could also be due to muscle loss. I've heard that after the age of 30 muscle mass decreased a significant amount each decade unless you take measures to prevent it. Seems like that could explain fat gain right?

@JustinaErcole Жыл бұрын

Honestly it could be a thousand different things, because fat gain comes down to holding onto more energy than you’re expending. So it could be muscle loss. It could be lack of movement. It could be stress. It could be hormone fluctuations. It could be almost anything as far as we know with the information we have.

It is pretty tough. In theory you really only need to study the one textbook. But it’s a lot. And you gotta really know the details. I took the exam once and failed the second half (I don’t think they split it into two parts anymore though). But honestly, studying so hard for it taught me way more than I ever would have from a regular personal trainer certification.

Look, I'm a med student in college and even when I am always interested in how calories affect our bodies I can tell you, at the end of the day it doesn't matter because our bodies don't read the labels and say: oh! This cookie has 50 calories and this bunch of strawberries just 20 calories. I should eat the strawberries and not the cookie because it's healthier… Yeah, fruit is always healthier but if you crave the cookie, your body will reverse the strawberries and store the damn fat in your body you're preaching to get rid of. Today, we still don't understand how this machine (our body) works a 100%, and we never will. Eat the cookie, eat the fruit and move a little. And please if you're 30 years old or older, focus on your strength training at least a couple of days per week because I don't know if you're aware, but you are now losing muscle till you are a 100 years old, and you leave your physical body to face the next challenge. You, Justina, are right and I personally don't understand why you haven't hit like the 500k subscribers already. People if you are reading this, subscribe to her, she shares good information also good training classes.

I've been pondering their Group Fitness cert, but it seems weirdly less involved than others I've seen (ie: NASM, my province's certifying body's recommendation, etc). I've really enjoyed some of their CEC courses (which my certifier does credit) and I'm tempted....

I have a question. If in the past, there were hundreds of studies that said age does matter with metabolism then why are we going by this new study that says the opposite? if hundreds of studies say age matters, why are we going by this new one?

@@JustinaErcole I see. So what do we do now with BMR and calorie calculators that ask for age ? Are they asking age because of the previous way of thinking? When I put in my age (40 something) vs 25 years of age I get a 110 calorie difference. Now what…lol. Not sure which calorie amount to go by

@@pamela6470 From what I understand, in this latest research they have compared the metabolism rate of people in a wide age bracket basically from 20 to 60 and so on (I don't remember the details). They have seen that there's not a lot of difference between the metabolism of someone in their twenties to someone's in their fifties or sixties. Hence, they have deduced that there likely isn't a big change of metabolic rate with age as previously thought. If I remember correctly, they have not compared the metabolic rate of a bunch of people when they were 20 and then when they were 60. I hope this helps. EDIT: checking the article they are actually talking about daily total expenditure that, from what I understand, is different from metabolic rate.

@@pamela6470 I honestly don't know cause I don't have a medicine/biology/nutrition background and I am not knowledgable about the methodologies used to perform this sort of studies. My very wild guess is that they are taking the assumption that there is enough variety in the cohort of people they have chosen for the study to remove possible bias. Some example of bias: someone may have had high enough metabolism to start with (when they were younger) and therefore at the time of the study their metabolism will be similar to someone younger but with lower metabolism rate to start with. In a sense they are assuming that averages over a big enough group (a representative sample in statistical therms) of different gender and age will give you the same result as doing averages over some time period for a small group of people, whose metabolism has been measured for decades. This implies that one can obtain relevant results in a shorter period of time. What are the implications towards those tools that give us an estimated metabolic rate, that require your age and assume that it decreases with it? I don't know. Those tools have been developed before this study came out, so it may be that we need to readjust them.
