Online Tennis Lessons & Video Analysis by Coach Jay, the Tennis Ninja
Send your forehand, backhand, serve, footwork, or match footage and receive a private online video analysis from Coach Jay — built around tennis physics, physiology, psychology, and practical correction priorities. Stop guessing. Get diagnosed.
Online tennis video analysis is a private coaching review in which Coach Jay studies your uploaded stroke or match footage, identifies the highest-impact technical or tactical problems, and returns ranked corrections, drills, and a clear practice plan.
- Private tennis video analysis with clear correction priorities
- Forehand, backhand, serve, footwork, and match-play breakdowns
- Real corrections and drills — not random tennis tips
- Ranked priorities you can act on — beginner to tournament level
Coach Jay draws the analysis directly on your footage.
Why it’s different
Not Generic Tennis Tips
Not Generic Tennis Tips
Real Tennis Stroke Analysis
Most players do not need another random tip. They need to know what is actually breaking down: setup, timing, racquet path, contact point, balance, kinetic chain, recovery, or decision-making. Every Tennis Ninja stroke analysis is built around three layers.
Physiology
Body sequence, balance, spacing, and a repeatable kinetic chain — what your body can realistically execute under pressure, again and again.
Psychology
Simple, prioritized corrections you can actually run when the point matters — instead of ten things to think about at once.

— Bobby N., PsyD · Palm Beach, FL

— Jana J.

— Erin M. · L.A., California
“I’ve known Jay as a Tennis pro for over 8 years. When tennis friends would come down for a tennis trip, we would contact Jay to run several clinics for the group. Not only did Jay make the clinic full of drills and critiques, he would also make it fun. For the past 3 years, I’ve been working with Jay as a private and semi-private student. He tailors the lesson to specific areas of the game that I need to work on. We discuss the purpose of the drill, his expectations of me during the drill, and then we discuss how I can apply it to matchplay. We also discuss previous matches and how to prepare for the next. Jay has helped me to take my tennis game to the next level by not only working on my technique but my mental game as well.”
— Sheryl K.
“Among his many talents in teaching tennis, Coach Jay is also an exceptional golf instructor, with the same knack for quickly analyzing your game, identifying your strengths and weaknesses, and applying appropriate remedies from a “quick fix” to a long-term strategy. He has a way with mnemonics to help the key points stick in your head so that you can continue to work on these areas long after the lesson has ended. He is a great player with boundless energy and enthusiasm, but not all great players are great teachers. The key to being a good teacher is bringing out the best in you, not trying to make you into something you’re not. Jay has that ability, and best of all you have a whole lot of fun with a terrific guy! My sessions with Jay will always stick with me and the pointers remain in my sub-conscience. Thanks Jay for your help, your friendship, and your encouragement.”
— Jerry C. · Palm Beach Gardens, FL

Pro Track: Remote Coaching Support for Serious Players
We know how hard it is to chase a real tennis dream when the money isn’t there — when you need the full-time coach, the travel, and the support the funded players get handed, but you simply can’t afford it. This is our answer to that. If you’re all-in on getting to the next level — rankings, scholarships, prize money, the tour — Coach Jay gives you the same technical analysis, match scouting, kinetic-chain review, and tactical planning of a full-time coach, at a rate built for players who are grinding, not spending. This is a service, not a sale — for players who genuinely need the break, not anyone hunting a deal. Pro Track is application-only: tell Coach Jay your goals and your situation, and he takes players on case-by-case, in the spirit of helping the ones who truly need it.
For dedicated lower-ranked pros, college players, high-level juniors, and rising competitors who need serious coaching without the full-time price tag.
Tier 1
Live On Court Training
$100 / hr
Or commit with a $399 5-hour pack (≈ $80 / hr) — for players who are in it for the long haul.
- Remote or on-court coaching & video analysis

- Tournament review
Minimum: 3-hour diagnostic block or 5-hour training block. Paid up front. Application required. Availability limited. Open to pros, college, junior, and amateur players on an hourly basis.
Tier 2
Breakthrough Bonus
Professional players only. College (NCAA), junior, and amateur players are never eligible for the percentage — they work on the hourly Tier 1 basis only. This protects their eligibility.
Simple deal: if you win prize money in a tournament after we work together, Coach Jay shares in the result — a flat 5% of that event's official prize money.
Flat, on any qualifying event5%
Kicks in once you win $7,000+ in a single event. Only official tournament prize money counts — not endorsements, sponsorships, appearance fees, or other income.
Optional and application-only. Set in a separate written agreement before any result. No results guaranteed.
Pro Track is application-only. All terms are handled case-by-case and an optional written agreement is required — terms must be agreed in writing before any tournament result. No results are guaranteed. Application approval is not automatic. This is not a legal offer; specific terms are established in a separate written agreement. The success-bonus structure is available to professional players only. College (NCAA), junior, and amateur players are not eligible for the percentage and engage on an hourly basis only. Minors require parent/guardian involvement and consent.

College, Pro & Advanced Players: Come Play on the Channel
If you're invited to play on the channel, you walk away with a full filmed session, your own pro-shot footage, and a real game analysis — the kind of day other players pay hundreds for. You pay nothing. It's built to make you look good and play better.
A Free Filmed Session
Real points and matchplay with Coach Jay on a local Palm Beach County court. One session, about 90 minutes — he handles the court, the cameras, and the editing.
Your Own Pro Footage
You get the full clips of yourself — clean footage for your own socials, recruiting, or self-review. Most players never get filmed properly. You will be.
A Free Video Analysis
Coach Jay breaks down your game on camera — the same expert analysis players purchase above, yours free for coming out to play.
It's part lesson, part show. You'll play real points and get a real breakdown of your game — filmed for the channel. Just be yourself, bring a good attitude, and enjoy it.
What we're looking for
Players who look good on court, love to compete, and have a genuine personality. You don't have to be a performer or put on an act — just be relaxed, confident, and yourself. The camera loves someone who's enjoying the game, and you walk away with a real lesson and your own footage.
What you're actually getting. A 90-minute session with Coach Jay, all of your own footage professionally shot and edited, and a full breakdown of your game. Priced separately, that's easily a $500 day — and it's free. Coach Jay gets one more video for the channel; you get recruiting-grade footage, a real lesson, and a clear plan for what to work on next.
Spots are limited. A lot of strong players apply every week and the filming schedule only has room for a handful, so not everyone gets a session — but if you're selected, the whole day is built around you.
Who this is for: college players (current or former), top juniors, pros, and tournament / UTR players — roughly UTR 7 and up (about a 4.5 and above) — in Palm Beach County & South Florida. This is real matchplay with a pro; if you're not sure you're a 4.5, you're probably not there yet (the stroke reviews above are open to every level). Nobody pays anybody: it's a session-for-footage exchange. NCAA athletes — this is free coaching and footage, not compensation; if you're unsure how it fits your program's guidelines, ask your compliance office first.

Questions
Frequently Asked Questions
How much do online tennis lessons cost?
Online tennis lesson pricing is simple: $89 for a Quick Stroke Review, $149 for a Detailed Stroke Breakdown, and $249 for a Full Technique / Match Review. Each is a private video analysis by Coach Jay, returned within a few business days of receiving your video link.
What kind of video should I send?
Clear footage of the stroke you want reviewed. A side view and a behind-the-baseline view work best. For match analysis, include full points before and after the mistake so setup and recovery can be evaluated.
How long should my clip be?
For a single stroke, 5–10 repetitions is ideal. For match analysis, a few full points or games. Quality and angle matter more than length.
Can beginners submit?
Yes. The review meets you where you are and gives you the one or two priorities that will move your game the fastest.
Can competitive players submit?
Absolutely. League, tournament, college and high-level players use these reviews for technical and tactical diagnosis. Serious competitors should also look at Pro Track below.
Can I submit match footage?
Yes — the Full Technique / Match Review is built for it. Send full points so patterns, decisions and recovery can be analyzed, not just isolated swings.
How fast is turnaround?
Most reviews are completed within a few business days of receiving a usable video link.
Do I upload video directly to the site?
No. There is no direct upload. You paste a share link from YouTube Unlisted, Google Drive, Dropbox, iCloud, PCloud, or WeTransfer.
What is Pro Track?
Pro Track is an application-only remote coaching option for serious competitors — pros, college players and high-level juniors. Tier 1 hourly support is open to all of them. The optional, separately-agreed written success-bonus structure (Tier 2) is available to professional players only — college (NCAA), junior, and amateur players are not eligible for the percentage and engage on an hourly basis only. It is intentionally separate from the standard review packages.
