This guy is the most likable guy ever.

I think you guys have some of, if not the best, tennis lesson videos on KZfaq. You guys have helped elevate my game immensely! Keep up the great work !!

Love this channel: the humour, the technical explanations, the demos, ...

i am impressed. You are so good at explaining and i never had this view of the slice serve being almost the same as a forehand slice. +1 subscriber for you

Dayday, this is the best video I've ever seen on the elusive slice serve pronation. Thank you so much!

Props for this video, you guys have done a great job at mixing the informative with creative and funny! Definitely will be watching more of your videos!

Right dose of science and good amount of progression drills equal best videos 👍😄

Going through the course now. Great work! It's rainy reason here in the Washington state so doing the drills will be a little difficult. I'll try my best!

Awesome training on tennis slice serves. Very professional video. I had to subscribe for more. I look forward to learning how to improve my tennis from your channel. Great job!

Love your hair man, also you're super energetic and insightful. Love your vids keep it up

Merry Christmas! Best of health in the New Year! Thank you very much for your great lessons!

Excellent video. Thank you so much for sharing. Really helps my service game.

Best video so far on the slice serve.

Love your format

This dude is just phenomenal in the way he explains things. I wish I could be taught by him.

Great work man , just great !

Very informative. Thank you!

Excellent instructions!!

I enjoy all your videos, fun and informative. Can you please make one about ball toss, and how to achieve consistency?

enjoy your relaxed smiling presentation - subbed and hope to learn more from you - like that big flat serve hitting the fence follow3d by a wide slice!!

Amazing. Such a great scientific explanation

Fantastic explanation!

Great lesson and great channel.

thankss for your explanation , so helpful

Thank you. I can hit pretty good flat and kick serves but not slice. When I saw your comparison with the forehand volée i understood i little bit more. I'm really bad at net so it's a long way. Start practicing this already today to give my game more diversity and take my opponents by surprise. This year I reached my best (National) rank and I want to improve again to make it to the top 10% of my Country.

Really well made video to learn slice serve

You are incredible, smart, funny, and pro, best video ever on serve

You are so good explaining everything thank you I have improve may serving

In the old days they made the ball turn back, from the bounce of a slice serve. So for a rh player, the slice curves to the left, and when bouncing, it kicks back to the right. This particular serve was used to hit to the T-area, making the ball enter the left side of the T, yet ending on the right side of the T. I think it was especially McEnroe, G Villas and Gerulaitis who used this as well as Borg. The spin on the ball is reverse to the flight / curve - the curve is produced due to the law of more distance / resistence air is required to travel, that direction an object will move, like the wing design on an airplane. As the distance over the wing is longer and air thus has to travel longer than the opposite air under the wing, the plane gathers lift. Likewise turning the far half of the ball to rotate, the resistence and thus time for air to travel across on that side is increased, making the ball go to the side of the shorter air path, as the air on longer path pushes the object towards where less air is being displaced, due to the spin applied. Yet on impact with the court surface, if not all spin has been brushed of during flight through the air, the remaing spin is still in the direction on the further half, thus to the right. That type of slice serve produces also more kick bounce from the topspin, whereas the cut slice, due to more backspin drag, will reduce its bounce height

love ur video, it helps a lot for me

Great videos guys! I love your explaining and drilling style! I also have a question, can you show the wrist action in slow motion, right after the ball contact in this serve type? I have real difficulties in imagining and exercising that wrist movement...Thank you! All the best from Germany! Lale

Thanks Coach.

great content guys.

you are to great dude!

GREAT teacher, great haircut :-) wonderful person!

🙏thank u man🙏4 your great videos 👊💪👈🫵😎🤙🎾🎾🎾🎾

You rock, bro.

Wow - you are sooo good 🎾

Thx good job boy

wow thank you~

veery well i understand

For slice serves, there are two types: (1) side spin plus under spin (without pronation, amateur) and (2) side spin plus top spin (with pronation, pro).

DD, great instruction: modify swing path with a delay in the timing of the inward rotation to contact.

Very nice

3:49 i was at first like "holy crap! They played Federer on Grandstand at the US Open???" But then I looked closer at the crowd - ... yep, this was just a practice match he played at the USO. :D (He probably played a practice MATCH for the grounds pass ticket holders; that is how cool he is - and how much he loves to play for a crowd). ... anyways, I love that you showed this, rather than a "prime time" match of his. That is a very cool court, by the way; it always reminds me of being on the freeway!! just outside of the court, trying to crawl off to the exit for Flushing Meadows. (The outside wall of the court is practically a wall of the freeway! Lol).

Great video, could you guys please do one for the top spin/kick serve as well?

Good lesson. The clock face method is the best. 8-2 o'clock is my bread&butter serve. Versatile, has curve as well as power opposed to hitting 3 o'clock. Placed well curves across the receiver's body producing a weak return. A 1 o'clock also curves then kicks off the court from the middle of the service box sideline. Are you in SoCal?

good vid

Wow I can’t believe how well these progressions worked well for me! You guys gave me an entirely new weapon. Thanks!

very good

Thanks for the great drills. You guys improved my serve(s) a lot. Don't miss a video of yours. Btw. is it mandatory to be a lefty to make it to the RacquetFlex team? 😀

You’re awesome brother…

Grrrreat video

Nice videos .. Please explain more how to delay internal rotation .. to play down the t n slice away out of the court ? What part of the ball should be sliced or played for the down the t ? Thank you...

N i c e!

awesome

Super

Muy buena la clase. La rotación interna es la complicada.

Great video! But still have one question regarding how to intentionally delay internal rotation. Could you guys give a more detailed explanation? Thx!

Nice video! Which grip do you use?

The clock from above was awesome. What’s the swing path for a flat and kick using the same clock?

thanks guys, could you please sum it up for lefties too

You play with that hair??? You re a hero!! I remember when i start playing as student my hair was as long as it is from head till waist... hehehehe...

Loving the hair! V jealous

Thank you so much! Cant wait to get on the court. Im the prince of double fault btw. Lol

Those are some really solid serves and it does look hard to guess where you serve.

What strings and tension are the yellow ones on your racket?

Please make a video on valley

I would love to see one of you play a singles match against someone.

How did you create those comic-like Federer images for your thumbnails? I think they look good

What is the correction for excessive ulnar deviation of the wrist, dominating the follow through and not allowing pronation, as a result of focusing on the motion of swinging the racket on edge or chopping the ball with the racket edge?

This bundle is worth every penny!

Love your content and good video ... but ... I've played just maybe three people in my 50 years of tennis that could slice using pronation. The best slice servers I've played all used the "doff the hat to the queen" motion accelerating the racquet around and under the ball and ending with the body in a bowing position and the racquet face pointing up.

I have a question. If a slice serve is easier when you toss a bit to the right but you’re worried about disguising it, can you develop a flat serve with the same toss instead of the other way around?

Hey Bro ! Amazing video. Just one technical question. For right handlers, that makes it 4 o clock to 11 o clock swing motion and not 8 o clock to 2 o clock as mentioned ya ? Insanely amazing content, just want to clarify this as my understanding is contact at around 3,4 o clock and swing towards 11 o clock in right handed slice servers :)

Please 🙏🙏🙏🙏 make a video on valley

BUG REPORT: The video is flipped/mirrored left-right in all the clips where you have short hair. (Your explanations are spoken for a right handed player) I assume it's a video editing error because the watch is on the right wrist. Examples: 1:12, 3:03, 3:36 I love your presentation style and tennis technique analysis, keep up the great work!

So saw a player performing a serve slice the ball spun a way from opponent which was great because made it harder to return. Is that heading at 3 o’clock????

Great video. When I slice, my racket is more vertical than my flat serve. But the rest is exactly the same. Also, the squash shot is more like Fed's slice serve because there is pronation on the finish. This is why the squash shot has a lot of pace on it, more so than your demonstration forehand slice. Please release your Fed serve video earlier. Thanks.

How to do the same from the Ad side?

This is by far the best tennis channel on KZfaq.

Federer T serve still has slice on it, just less than his full slice. It’s not flat. Almost nobody serve actually flat. Usually always some degree of slice side spin on it.

Please do a video on "how to avoid tennis elbow"

It’s been an year.. where is the kickserve video.. I loved your explanation on forehand and serve.. I have just learnt to do a flat serve but it isn’t consistent.. I wanted to learn kickserve as it is probably more reliable.. Found your slice serve video but I think slice is more variation of the first serve than the second serve..

The serve bundle link doesn’t work btw.

Again, this guy is one of the very few to watch...thanks for the lesson!!

The tennis serve is a crucial shot that can greatly impact your performance on the court. Learn it

His laugh made me better at tennis

Are you in california teaching? I want lessons.

Spin isn't created by brushing the ball, it's created by hitting the ball off its equator relative to the swing path, i.e. closed face relative to swing path

7:48 👀🎯

link doesnt work...

Dayday has a brother? One bro is a lefty and one bro is righty? Which one is which?

Pro Wta player Sapfo Sakellaridi stopped this video at “toss at our head” :)

Thanks, but in slow Mo, we clearly see front carve instead of side carve.

I see stoney brook. I see dayday... I see daytri. Where is Momo?

Drop your hair care routine my boy

Was I the only one that worries about the lefty’s foot fault 1:15

...and step number 4 is:The aerodynamic hairstyle.

1:15 FOOT FAULT!
