This is the first time I make a 3d model that features a flat ledge. Honestly, it took me quite a long time to make one and the script of this video is quite messy.
Anyway, we attempt to break down common problems that we experience while trying backside 50-50 grind in skateboarding using 3d models and physics theories.
Please take a moment and try to study this in detail.
I'm trying to eliminate subjectivity from my explanation as much as possible by referring to scientific and physics theories. Please use my 3D models to solve your "why."

Traditionally, skateboarding how-to videos have always been subjective and the majority of explanations are based on speakers' experiences.
To avoid relying on my personal experiences, please fully utilize the 3D models.
All skaters have different questions.
So that you can analyze skateboarding tricks in detail and solve your "whys," those 3D models are made fully interactive.
The 3D models feature these functions below:
- change camera angle
- adjust play speed
- change transparency
- display gridlines, etc.
Aside from that, I try to explain concepts of skateboarding tricks based on facts, calculations, scientific and physics theories. I may make mistakes so please leave a comment if you find anything.

Do one of these for tailslides. The physics as to how and why tailslides can be so difficult to do at first is truly amazing.
The biggest thing I think that makes tail slides difficult is the timing, which is why it’s easier at an angle with more speed. You need to pop and clear the ledge before turning to land in tail slide
dude ive got a tip for you that made me learn back tailslides in literally 1 day lol. So if u have a bed with a big edge u should just try jumping on this edge with ur bare feet, like just jump on it like if u were doing back tail and control the balance, it made learn this trick so fast

BS tail please
Back 5050s took me a long time to get, but for some reason they are much easier than frontside to me now….what helped me get it at the end is when I realized the trajectory you travel is similar to how a car merges into traffic onto a highway, like curving into a straight line moving forward. The spot you’re landing on is actually front of you, nose-side, rather than thinking about jumping onto the ledge located behind you.
Very insightful, thanks
Man the concept of this channel is something I always wondered about. So cool to see someone, scientifically break a trick down in most effective way. Keep up the great work dude🤯🤙
Glad you enjoy it!
BEAST!! love the 3D model keep up the grind you just earned yourself another sub.
This is an amazing video mate, with a completely unique view. Can’t wait to see what trick you explain next.
so cool, still trying to get more height on my ollies and i think your explanation of the thighs lifting the body and the calves doing the pop a little bit after will really help :)
I'm so glad I found ur channel love it it helps out alot and I've been skating 15 years
Absolutely love your videos and especially the 3D modeling!!! awesome!!!!!! Keep shreddin!!!!
This really made sense I really liked this video. Good stuff dude
So helpful bro. This really looks like it will help me to do tricks while rolling. The physics and showing how the muscles are utilized are very key concepts, ones that I haven't seen utilized before 👍
I feel like the biggest part imo is the backside shifty that has to happen. It's so drastically different from a frontside 5050 in the sense that for a fs 5050, you can stand parallel & close to ledge. With bs, your heels hang off and you have to be further away from lesge so as not to hit them, & jumping backwards is so much harder too. So a good speed & a good backside shift are key, atleast for me
the backside shift for me
Aim your front truck while making shoulders parallel with the ledge and your back truck will fallow
@@mccullsn Exactly. I feel like people make bs 50s way harder than they actually are. You do not need to angle this much to get into a 50 backside, like the angle he is coming into the ledge in this video is really exaggerated (This is also a lot of people's problem FS as well). But hey whatever makes you more comfortable with it go for it. I personally think you should be as parallel as possible and have a slight angle or lean on your heel side at a different time as opposed to making a super wide cut. Definitely will make you more consistent and you won't miss the ledge. This is especially important when going for bs 5-0. If you angle too much you won't lock in right. I try to think like I'm getting into a manual on top of the box but just line up with the edge and everything goes pretty smooth, same for 5050. Hope this helps some people
Yeah, that's because your board naturally goes forward when you Ollie. Think about it, when you stand up, your feet are below you, when you lift your knees your feet are... Infront of you! That's what you are working against when you BS 5050.
I am skating for a long ass time but my bs 5050 still suck. I wouldn't dare to try a bs 5.0 because I never seem to get onto the curb in the right angle. I either not rotate my shoulders enough or miss the back truck.
I'm also going with a decent angle because I think otherwise I will miss the curb edge.
Should I really try to be parallel and if so, what should I care about in the motion?
I feel it is so hard to practice the motion because with little curbs I have no problem but as soon as the curb gets bigger, I never seem to hit it right...
Love watching your vids, meets my high level of intellect plus I get to Improve drastically in my skating!
This feel true to this and some other tricks where the approach to the obstacle/trick is awkward/uncomfortable by definition, so you don't execute your pop/ollie to the best of your ability/confidence because of it.
For instance, you may probably be able to ollie over/onto the ledge just fine, but because you are trying to approach it to backside 50-50 (more awkward approach than frontside, for instance), then you ollie not as good/high as you can because of that feeling.
I think this video besides pointing out specific corrective actions, it also gives us that general insight/awareness when it comes to the awkward/uncomfortable side of grinds/slides.
thanks for the comment and such detailed insight!
Love your vids man!
bro this is the best channel out omg
Happy Friday.
Huge thanks to everyone's support.
OMG
Thank you!!
I'll try this later
I always experience the difficulty for the timing
Please create more videos like this
This is an awesome channel! Mixing theoretical and practial physics 😅
I was wondering why you uploaded so early today, but it's probably night time in Tokyo now and it's actually 8:3ú and the sun just rose here. Anyway, I'm happy to see you uploading consistently. Your videos really help me understand. For example, I couldn't drive a stick shift car, but once I understood what happened in the car when I'd have to shift, I was able to drive. Same with skating.
Thank you for the comment. Yes it’s midnight here. Have a nice Friday!
wow this is an amazing video and I actually learned something! thanks!
Love these videos keep going
im tryin bs50 for months and my problem it just on part 1
thanks for the video!
One love!
this trick is one of the chillest once you locked them in its a great warm up trick and also easy on the body
thank you weve needed this
Great video. It's the angle your coming at it thats making it difficult. Come almost parallel to the ledge so you can keep your shoulders squared to help you stay locked on the ledge longer. Once you get it down you'll find backside to be easier than frontside.
Its like you are doing part of a late backside 180 mid air while jumping on a ledge, and it instantly lock in
good videos, I've been skating 16 years and have never thought about tricks like this. skating physics
I love your channel good video ! 😀
LOVE THIS CHANNEL
thanks a lot dude! you make amazing videos!!!
they feel amaaazing... when you said that it sounded exactly how it feels
Thank you. Keep going! Your Chanel is gold
Thank you! It doesn’t mean anything if it were not for you precious visitors.
Nice break down!
Amazing video! Thank you so much!!!!!!
Favorite new channel.
Thank you for this video it helps a lot
Bs 5050s r like my arch enemy. I am super interested in trying this delayed pop concept. I'm gonna try it out today
Those r the sickest parks btw🤩😍!!!!
Update: HOLY SH#$T THIS WORKED 100%!!! I SUCKED AT BACKSIDE 5050 AND THIS JUST CHANGED THE COURSE OF MY LIFE. THANK U SO MUCH!!!!
though for me personally the issue with back 50s was the slight backside rotation. ollieing onto a parallel sidewalk backside helped me a lot. also trying them on a pole that's laying on the ground. great way to get used to locking into any ledge/rail trick/combo.
I remember my friend taught me these when I was little and I never forgot them . You want to go at a angle like a inward B's 180 on the coping
On most of your problems you're leaving your back shoulder behind. Alot of backside ledge tricks are in the shoulders.
This. Finally started to land these switch and after you got decent ollie down, it's all in the shoulders
good looks, i think i just discovered the technique
totally agree
that´s why it´s easier for some people to do switch bs grinds, because the shoulders stay closed naturally
@@aimlessdrive8723 He's good with the physics of the board itself & certain foot placements( pressure points). Alot of people fail to explain the shoulder/waist/feet relationships. That & knees/posture.
another great video. thanks
Great content!
Great work amazing video! Please make more. Maybe you could do even more difficult tricks with the help of a skater that has them down
I don’t think there has ever been a skateboarding channel like yours. Other channels can tell you how to do certain tricks, while yours can show you scientifically how the trick works and what to do with a greater understanding of why what you do works.
Such a dope channel
Wow those first transition clips were sick ! I’d truly appreciate some on rock fakies and disasters if that’s possible man. Street skater trying to do more transition!
now this is good skate content!!
and that's a good comment.
thanks a lot!
cool video. I felt like the pop was never the issue but looking at the coping and lining my body up with the coping when I pop was the issue. When I did this, I could line up my back 50 much easier
We need one on back tails ASAP. Love ya vids
This is awesome
amazing video
Plz never stop uploading
I won’t! Thanks!
INFORMATIVE thanks.
Thanks for the comment!
i love your channel!
These videos change the game fr
amazing!
Thinking of the bs 50/50 as doing a shifty ollie, with emphasis on shifty and learning shifty ollies was key for me learning the bs 50/50
Loved doing backside 50-50's and easiest way was to go parallel to the ledge and not at an angle.
You are someone amazing man
I think about looking over my back foot right after I pop. It's weird but it allows me to keep my shoulders straight and parallel to the ledge, and to focus on locking in the back truck. think of doing a 'mini backside ollie' too
I rlly just got a physics lesson and I loved it
skating physics^*
I would love to watch this type of videos for all transition tricks I am strugling with. 🤩🤩🔝🔝
Thanks for the comment. I’d very much like to make one.
Thanks!
With most ledge tricks, think of doing a solid ollie, and the board is stuck to your feet, aim your feet where you want on the ledge. Rotating shoulders comes next and that's harder to explain but being parallel for basic grinds, and slightly off center for advanced grinds, perpendicular for slides.
very interesting
the mind battles are the worst ones, I can do kickflip bs tailslide, f-0, noseblunts you name it, but I can't do any of those tricks without the kickflip, it just feel weird
Can you do a video about landing drops? And how your skateboard helps with impact.
keep uploading videos please! you are a fucking beast
Pretty much judgement when to ollie like when ollie over obstacle. Its like ollie up on top the ledge at angle if too acute your weight will cause to struggle balance.
I love your videos. Can you make a video on backside 180s and/or 360s please?
Thanks a lot! Working on it…
Turn your shoulders backside (front inwards) during the ollie. Put more emphasis on front, imagine like going for nosegrind but slapping back truck in aswell, if you know what I mean.
You should do a video on backside 50-50s on transition
Great Video! Can you show what difference the concave on a skateboard does (low, mid, high..)
Thanks for the comment. Sure thing.
If you could, maybe cover transition skating and it’s physics. Flat ground physics make sense to me but theryre are a bunch of variables in transition skating (pumping, shifting weight, grinds, ollies & more… all on ramps and bowls there is so much haha)
Nice,, Please make "How to axle stall" .. thankyou🎉🎉🎉
I fell once to the point to where ill never forget it was like my legs went parallel. before any fall occurred all the way to the box. lol. happened like 15 years ago. STILL know the feeling it was like a scar ran all the way up my inner bottom half of my leg. it went away. but it was like something that shouldnt even happen. lol.
Can you do one on frontside 5050s? I can never seem to get them to work
Also those parks look like so much fun! Where are they?
Nice, a grind trick video, shame we got no skateparks. Best we got here is some crappy marble ledges in the street.
Oh, I also took your advice and went snowboarding at like -20 Celsius. I thought it’d be quite similar to skating but boy, was I wrong. It is completely different.
Thanks for the comment as always. The faster you move, the closer skateboarding and snowboarding becomes. I think it’s because the same physics applies to them…ah! that must be fun to talk about. Thanks for the idea.
@@whythetrick When I gone faster, yes, it did get more stable, but even like a 5-10 turns while going faster can leave you spinning. While I was learning, I found something interesting about myself: I place my front (left) foot more forward when I’m riding a skateboard and a snowboard, so I keep on turning backside, when I try to fix myself and move my front foot back, I turn frontside way too fast, thus getting into an surprise powerslide that makes me fall face-first (In my head, I was literally telling myself “Don’t fight it, don’t fight it!”)(Surprised how this simple explanation got this long).
back 50s are so much harder than they should be!
all about cross locks tho but need to use a round rail for demonstration as a ledge you don't have to balance, cant cross lock etc
Just a suggestion. Try going more parallel to the ledge with little angle. When you Ollie from a big angle naturally it will make it hard to lock your trucks. Usually I like to be less than 30 cm from the ledge before I pop.
For me the explanation is simple. When you Ollie, as your knees go up, they also go forward Infront of you, so do your feet and the board, meanwhile fs 5050 is way easier and even possible to get on it riding parallel to the ledge. BS 5050 though, you have to go at an angle and scoop the board behind you. It's hard to get the board behind you when it naturally goes Infront of you. The higher your knees go the more forward the board goes if that makes any sense.
thanks for the comment. great point!
So your telling me you learned blender to teach skateboarding.... wow... subbed
Wow.
My trick is to guide with your front foot, even though you are approaching at an angle, slide your foot parallel with the box or ledge, and the board will follow and straighten out with the ledge, and just make sure you are picking your back up your back foot. pop high and commit, slide foot parallel with box, pick up back foot.
Great tip!
I'd really like to see the science behind 180s, how and when to spin, as well as how to get them high
Thanks for the comment. Fs or Bs??
@@whythetrick I myself have more trouble with bs, I know a lot of people would agree with me. That's why I think it'd be a good vid. great stuff keep it up
How to backside tail and backside lipes
Keep shoulders in line with the board and approach the ledge at less than a 45 degree angle. They're actually easier to hold than a front 50
it may sound silly, but try changing the word difficult , to challenging , not only in skate, it kinda works on your subconscious. little by little its been working for me to try things and tricks ive always had held back to.
what's that?
@@whythetrick thaaat,what? trick? sorry i dont follow
I've found that looking over your leading shoulder can cause problems. Instead, I either don't look at the ledge or look between my legs.
When I was like 12 I fell on my ass so hard I cried trying this trick. Tailbone straight to the angle iron. Was determined to learn back 50s ever since and now it's easy. It's all in the shoulders and getting the right angle riding up to it. Personally, the angle is only a few degrees with shoulders parallel to the ledge. I almost do sort of a backside shifty but ever so slightly.
Thanks for sharing your thoughts. Helpful indeed.
good video
Thanks for the great comment!
Very cool! DId you do the animations yourself? If so how?
Thanks for the comment. I do make animations based on my videos. I just use tools called Blender and Three.is and others, and spend just quite a lot of time.
Fs grind are harder to hold I mean for a long long grind . Do y’all think it too?
Well done video, amazing 3D-Animation! But I guess the 50/50 is "just" about board control (you might need to skate about one or two years to get it good). I don't see a secret in that trick to be solved by science. The grinding isn't difficult because your board is still in riding direction.
But there are other tricks that make skaters insane because of not finding out to execute. For example not being able to slide a (long) BS Tailslide. Or some flips such as hardflip and inward heelflip. I would be really interested to look on THAT problems from a science view.
Next, bs nose slide!!!
Dude.... WHERE are you skating??? (at: 0:15 min) it looks amazing!!!
thanks a lot. it's setagaya park.

Do bs feebs how to lock in thanksss
How do you even pop on the way down lol? These problems have more to do with body weight distribution and shoulder position. If you want to back 50, the main thing is to lean back toeside when you pop and align shoulders with the ledge. You don't need a crazy angle like that either. All of my backside grinds/slides got more consistent once I started going parallel.
I have trouble hitting them high on angles, but I'm training up with BS slappy 50's.
I can't get over the sign that says "don't be naked" 😂
Bs 5050 its a pain , but unce got The shouders right its fun
