Checklist
Stance
Diagram
A checklist is only useful if you can actually check off each item. These 6 checks for improving your Universal Tennis Rating (UTR) can all be done using just one video from a single, consistent angle. You won't need any extra equipment.
The Checkpoints

1. Setup consistency
Pause the video at the first frame of your swing. If your stance, the distance to the ball, and your alignment change every time, it will be hard to tell what's going wrong later in the swing. Consistent setup makes everything else easier to analyze. To check this, compare the first frames of three swings. The outlines of your body should look almost the same each time before you can trust any conclusions about your swing.
2. First move direction
Watch the first part of your swing in slow motion. The initial movement of your hand sets the path for the rest of the swing. It's the easiest place to spot a problem early. Check by watching the first ten frames of your swing: the movement should start in the same direction and at the same speed in both good and bad swings. If it doesn't, you've found an early issue to explore.
3. Timing under speed
Compare a practice swing with a full-speed swing. If a problem only shows up when you're swinging fast, it's about timing, not just body position. To check this, count the frames between two points in each swing. If the timing changes when you swing fast, that's where things are going wrong.
4. Contact window
Look for the frame where your racket hits the ball. The timing and position of this contact explain a lot about how the ball behaves. You can see this clearly on any phone camera if the angle is steady. Check by going frame by frame as you make contact in three swings: the contact point should be in the same spot relative to your body each time. If it shifts, that's why your shots are inconsistent.
5. Balance at the finish
Pause at the last frame of your swing. If you're off balance at the end, something went wrong earlier. Balance at the finish sums up how well the whole swing went. Check by holding the final position on video for a couple of seconds: if you couldn't hold that position in real life, something went off track during the swing.
6. Miss direction pattern
Record the results of five swings. One miss might be random, but if you keep missing in the same direction, it's a clue to what's wrong. Check by writing down the result of each swing before reviewing the video. This way, you can see if the video matches the results you wrote down.
How To Use This List
Go through the checks in order using the same video clip. They start with the easiest and most obvious issues and move to the more subtle ones. Mark each check as pass, fail, or unclear, and don't try to fix anything while you're reviewing. This list is for diagnosing problems, and it's best to finish diagnosing before you start practicing. Remember, a phone video gives you an estimate, not precise measurements. Build your confidence by repeating the same task under the same conditions.
If something is unclear, it doesn't mean you're unsure. It often means your camera angle or the number of swings isn't enough to make a judgment. In that case, better footage, not a swing change, is the next step.
How To Choose Where To Start
Begin with the first check that fails, not the most obvious problem. Early issues can cause later symptoms. Focus on fixing that one thing, practice it specifically, and then retest with the same checklist. If you need more structure, the tennis swing analysis, get started, topspin forehand, analyze tennis paths follow the same diagnose, fix, and retest cycle described here. If the problem causes pain, gets worse, or doesn't improve after focused practice, consult a qualified coach who can see your full movement. A digital guide can help organize practice but shouldn't replace medical advice, safety judgment, or in-person coaching when necessary.
Next Step
Checklist
Practice it in 4 steps
Drill sequence
Set up the rep
A consistent target and starting routine, so every utr improvement rep is comparable.
Make one key change
The smallest change that attacks the likely utr improvement cause — one cue, not three.
Drill it slowly first
Controlled reps below full speed until the movement feels repeatable, then add speed.
Retest at game speed
Same target, same scoring rule as the baseline — keep the fix only if the result moved.
Checklist
What stalls the fix / What makes it stick
Fault vs fix
What stalls the fix
- 01Changing grip, stance, and tempo at once while chasing utr improvement
- 02Judging the utr improvement change by feel instead of the ball or contact result
- 03Practicing only slowly, so the fix never survives game speed
What makes it stick
- 01One change aimed at the most likely utr improvement cause
- 02A small scored retest after every drill block
- 03Adding speed only once the outcome holds
Record one swing today and apply all 6 checks to it. The first check you fail is your focus for the week; retest the checklist after your next practice. Measuring your progress is more valuable than just remembering what you did.
