Summary

If you’re serious about building muscle quickly and effectively, there’s one fundamental concept you need to master: the difference between mechanical stress and metabolic stress. In this episode, I break it all down for you. I explain what each type of stress means, how they work, and exactly why they’re both essential for muscle growth. Mechanical stress focuses on heavy lifting, progressive overload, and creating maximum tension in the muscle fibers. Metabolic stress relies on the "burn," higher reps, shorter rest periods, and techniques like supersets and drop sets to push your muscles to the limit. I also share practical tips on how to program these methods into your workouts so you can stop wasting time and finally start seeing results. Whether you’re new to strength training or looking to break through a plateau, this episode will help you understand the science behind muscle growth so you can train smarter, not just harder. Tune in and get ready to transform your workouts—and your physique.Keywords: build muscle fast, mechanical stress, metabolic stress, muscle hypertrophy, strength training, progressive overload, workout science, fitness for women, bodybuilding, muscle growth strategies, fitness podcast

0:00.0	Hey, team, how you doing? Welcome to the Kim Constable podcast. Nobody cares work harder. I'm actually live here on Instagram. This or not on Instagram, live here on YouTube. This is the first time I've ever actually recorded a podcast live. But I thought that I record these podcasts, well, usually weekly at the minute. But I never actually just hit live, you know, go live on
0:22.8	YouTube. And I thought, well, why not go live on YouTube, record the podcast live? If there's any
0:27.6	questions that come up, I have my computer here. So I can answer any questions for anybody who jumps on
0:32.2	live. And I think I'll do these live every week from now on. And I'll set up a specific time when I'll go live and you guys can can join in and ask questions directly during the podcast interview.
0:45.3	Isn't that like, or not interview. I can't even speak today. Directly during the podcast recording. It's actually so cool to be able to do new stuff like this. I've been changing up a lot of stuff in the business
0:54.5	and the way I do things in the business simply because I do believe that because of AI,
1:00.5	the way that the world is working and the way the online world is working is actually
1:05.7	changing quite a bit in terms of, you know, everybody is doing highly created videos now. Everyone is using
1:13.0	AI. Everyone's using chat GPT. It's very hard these days to find out or to figure out what is real
1:19.6	and what is not because so much of what is written is written by chat GPT. Here's actually
1:25.0	just a little side note. Here's how you can tell if something's been written by chat gbt first of all there's loads of emojis um or emoji maybe that's the plural of
1:33.3	emoji is emoji uh chat gptt loves using emoji so if something has a lot of emoji in it you know it's been
1:39.9	written by chat gptt also long dashes in the middle of the words so long dashes are not something
1:45.3	anyone would normally write in a sentence or in a paragraph or whatever but chat chbt
1:51.1	always uses these long dashes so anytime i use chat chb t to write anything i just go ahead and delete
1:56.6	all the long dashes afterwards because i don't want to sound robotic like everybody else.
2:01.5	And also the reason why I've started doing a lot more lives and a lot more podcast recordings
2:06.6	and, you know, these live YouTube recordings is simply because I think that in a world where
2:12.6	we are increasingly on social media, we are increasingly scrolling on our phones. We are seeing so much
2:18.8	AI stuff coming out. Now, I think sometimes it's hard to know what's real and what's not.
2:23.3	And I do think that the world is going to make a huge shift back to wanting real people, real
2:29.2	content, wanting to see more live style training and live interviews and podcasts and Q&As and that kind of
