It's time to get serious-and smart-about training your legs. Learn the inner workings of your lower body to maximize your growth in the gym!
If you're serious about building an aesthetic, athletic physique, you simply have to develop your legs. Training them not only helps them look great, but also gives you a strong, stable base for improved performance and additional physical power. In my opinion, your legs are the most important muscle group to train, hone, and build.
And let's be honest, there's no way you can build the size and strength you want without using your legs. They're literally half of your body.
I'm here to teach you more about the muscular and skeletal anatomy of your legs. I'll also teach you select exercises that can help you build a strong, shredded, and muscular lower body. This trainer brings science and squats together to help you build the lower body you've always wanted!
BETTER LEGS, BUILT BY SCIENCE
We've covered a lot of information, but I hope you understand how important your hips and legs are. If you need to, go back and watch this video again. I want you to get as much out of this trainer as you can. Put this all together and learn why we're spending time on our legs. To get the most out of our training and the most out of our physique, we need to train legs. As the saying goes: Friends don't let friends skip leg day.
FOLLOW THE BUILT BY SCIENCE PROGRAM
Look for the exercises and techniques discussed above in the weekly legs workouts of the six-week Built by Science program. Watch all the overview videos before attacking the gym. Remember, you need to combine mind and muscle to build your best possible body.

I feel like I just attained a university degree in Health & Sciences after watching this.

[@JohannaMueller57]

that's right - a 25 minute video and a degree are about the same. ;)

[@ZockaBrotha]

+JohannaMueller57 calm down, he said that he feels like he attained a degree

[@schmidty5107]

+Daniel McIsaac Now that's an express course, I tell ya what.

[@chrisryan6464]

It means you have low standards dude. And that is the problem nowadays, people watch you tube videos and think they are being enlightened so they go and share their stupid opinions online and in person.

[@alexmalabre767]

For real this channel is very educational

[@nezludel]

straight video game character this guy is

[@whatthefckd9208]

Agreed

[@mitchwow5325]

Jake Lewis I was literally just about to say that looool 😂😂

[@Pixxelina]

Mike, I could listen to you teaching all day long. This leg lesson is so thorough and comprehensive, it makes it easy to understand how to shape your legs. Thank you for sharing your knowledge.

[@chris71388]

I'm studying college anatomy right now. This is great stuff.

[@user-ld3dl2hi7n]

ok

[@ocean_kp]

I'm currently training as a PT and these videos are absolute GOLD. So great for bringing together so many concepts and the teaching cues for these exercises are brilliant. This guy has SO much knowledge and breaks it down in such an easy way to understand because of it's practical relevance. I'm going completely back to basics now with my training, super low weights and will be trying to get these techniques sorted - love this channel have totally subbed!

[@nationalstudentclearinghou6303]

When you are a medical student, studying for anatomy exam, and you watch this... great!

[@briankenyan1799]

I'm so happy to be part of this

[@DaveO0808]

Craig, just standing there and relaxing, looks 10x better than I do flexing and posing all kinds of shit lol.

[@pizdecki]

Great video! As an Art student but also a lifter I find this very useful when it comes to understanding anatomy and how the body works while in motion. Looking forward to see more episodes.

Been looking for videos like this for a long time :) great work, guys!

[@zstrizzel]

Wow, just learned more about my legs muscles watching this than any other video/article I've seen. Thanks guys.

[@1995Benzo]

Craig has the perfect leg anatomy for this amazing course.

[@mattmsantos]

That guy has sculpted a great body!

[@Anonymous_Pi]

This man Craig is literally 100% muscle.

[@alejandroguerrero5425]

This videos are super, love the clear instructions, easy to follow, I am hooked.

[@Logicyo]

funny how this has the least amount of views compared to other anatomy items. DONT SKIP LEG DAYS U POPISCLES!

[@cameronellem7144]

+Logicyo ahahah so true i had to double take views!

[@Siberius-]

+Logicyo - If it was a woman it would of gotten the most views so people can perv on her ass. Also I don't think many bodybuilders are skipping leg day.. squats seem to be all people talk about lol. Probably the number one exercise I personally hear about the most.. I'm talking about people who at least know a little bit about bodybuilding and not highschool noobs who want only biceps.

[@vanslededesign3386]

+Logicyo I also noticed that, when it is about the legs, anyone want to ignore.

[@aloysiuspendergast7221]

+Logicyo Big legs are bad if you want to do gymnastics moves like planche. Some legs are ok

[@Darkdodge]

Couldn't be more correct.

[@keitavanryckeghem9357]

I'm fitness instructor/PT and this video is a great overall remind of what is the anatomy of the legs and how it's work for improve your strength and grow up your muscles. Great video!!!

[@nicotate07]

Man, i love this serie of videos. Today I learned a lot :) Thanks!

[@jacobdrumm9206]

Thank you so much for the quality information taught in a way that's easy to understand and entertaining. I've been needing to learn this for too long and I feel a lot better now that I know. Keep pushing out that knowledge!

[@marioescalante343]

Great series. Would've loved to see you explain the front rack arm position for the front squat. More control of the par and better posture, despite it being a challenge if you dont have the mobility. The cross arm position is not ideal

[@ryankenny7310]

This video is the perfect example of education vs know how knowledge. He sure taught me a lot about anatomy, just to show you four basic leg workouts. It is interesting to see how the body works, but I want videos of secret lifts that isolate certain muscles.

[@chijioke4997]

I have always known from the few times that I attempted the front squat that it should be the most beneficial leg workout but I still find it difficult to hold the bar close to my neck and I can't go higher weights when I do it. This tutorial had helped me to understand that the front squat position is not comfortable for everyone . So I will go ahead and push for more front squat

[@atheist-agnostic-believers]

The amount of quality this video has!

[@julinization]

Man, I feeling like the leg muscles are not growing, will never skip leg days again. Great vid.

[@techypicks]

[@miklas-dj9kd]

I want a Craig to move around for fun. Would've been funny if when the instructor said "go ahead and give me a quater turn here, Craig", Craig just said "No, Craig hungry". Great series, tho. Easy to understand and packed with information.

22:00 - can also use leg press machine after doing presses, put the ball of foot on the bottom of the plate after deloading the stack. Knee's straight and allow the weight to dorsi flex then press back out :) good to do after your quad set.

[@VikasYadav-hf7eo]

thank you for using the correct terminology and not dumbing it down..... also the tibialis anterior would of been a much needed muscle to talk about since it gives you width of the lower leg when looking at a person from the front....other then that great video and series.
