Short answer
The most common disc golf form mistakes come down to timing and position: the arm starting before the hips, the shoulders opening too soon, a soft front leg, the pull drifting away from the body, and a finish that falls off balance. Below are 20 common disc golf form faults, 10 for backhand and 10 for forehand, with what each looks like and the camera angle that can actually show it. Film from the side first, add a behind or front view for sideways faults, and fix one fault at a time.
This list is the exact set of 20 faults that Disc Golf Form Analyzer grades. A real coach defined them for our app. The descriptions below are mine, written for this guide; the coach's own explanations, cues and drills live inside the app.
Disclosure up front: I build the app. You do not need it to use this list. A phone, a steady spot to set it and a bit of honesty with the pause button will get you most of the way.
Before you start: film it properly
A fault you cannot see is a fault you cannot fix. Two rules matter most.
- Pick the angle for the fault. Some mistakes happen front to back (posture, plant, weight shift) and show from the side. Others happen sideways (rounding, chicken wing) and only show from behind or in front.
- Keep the whole body in frame from the start of the reach-back or load through the finish, with the phone still.
Our full setup guide is how to film your disc golf throw for form analysis.
The 10 common backhand form faults
| # | Fault | Best camera angles |
|---|---|---|
| 1 | Poor loading sequence | Side, behind |
| 2 | Early rotation (opening up) | Front, side |
| 3 | Poor athletic posture | Side, front |
| 4 | Weak front-side brace | Side, front |
| 5 | Poor plant timing | Side, behind |
| 6 | Rounding | Behind, front |
| 7 | Early upper body rotation | Front, side |
| 8 | Losing the power pocket | Front, behind |
| 9 | Incomplete weight transfer / rotation | Side, behind |
| 10 | Poor finish and balance | Side, front, behind |
1. Poor loading sequence
The load is how you coil and set your weight before the forward move. When it is out of order, for example the disc goes back but the hips and shoulders barely turn, or the weight never settles on the back leg, there is nothing stored to release. Check: from the side, at the end of your reach-back, is your weight over the back foot and are your shoulders turned well away from the target?
2. Early rotation (opening up)
Your body turns to face the target too soon, often before the front foot has landed. The throw loses the stretch between hips and shoulders that powers it. Check: pause on the frame your front foot lands. If your chest already faces the target, you opened early. Full guide: opening up too early.
3. Poor athletic posture
Standing too tall, bending at the waist instead of the hips, or locking the knees makes it hard to rotate and brace. Check: from the side, look for a slight knee bend, a hinge at the hips and your head roughly over your stance rather than drifting back.
4. Weak front-side brace
The front leg is supposed to stop your forward momentum so the upper body can whip around it. If the knee collapses forward or the body keeps sliding past the plant, energy leaks out. Check: from the side, watch the front knee from plant to release. It should firm up, not keep folding. See hips, brace and weight shift.
5. Poor plant timing
The front foot lands too early (you wait and lose momentum) or too late (the arm is already pulling). Check: from the side, where is the disc when the front foot touches down? On a well-timed throw it is still near the back of the reach-back.
6. Rounding
The arm swings out and around the body on a curve instead of pulling the disc close across the chest along the target line. It is the classic backhand fault. Check: from behind or in front only; side-on hides it. Full guide: how to stop rounding your backhand.
7. Early upper body rotation
Different from opening up as a whole: here the hips may be fine, but the shoulders and chest unwind ahead of them, so the separation between hips and shoulders disappears early. Check: from the front or side, compare the line of your hips with the line of your shoulders at the plant. If the shoulders have already caught up, they fired early.
8. Losing the power pocket
The pocket is the moment the disc passes close to your chest with the elbow bent and leading. Lose it and the arm straightens early and swings from the shoulder. Check: from the front or behind, pause as the disc passes your chest. Is it close to your body, or already out past your shoulder line?
9. Incomplete weight transfer / rotation
The weight stays on the back foot, or the hips stop turning partway, so the throw ends with you leaning back or facing sideways. Check: from the side or behind, at release and just after, has your weight moved onto the front foot and have your hips turned through?
10. Poor finish and balance
Falling off to one side, stepping out wildly or spinning off the tee after release. It is often a symptom of something earlier. Check: any angle. Can you hold your finish for a second or two over the front foot?
The 10 common forehand form faults
| # | Fault | Best camera angles |
|---|---|---|
| 1 | Poor lower body load | Side, behind |
| 2 | Collapsed / unstable load position | Side, front |
| 3 | Chicken wing (elbow escape) | Front, behind |
| 4 | No lower body sequence (arm-initiated) | Side, front |
| 5 | Losing the compact forehand path | Behind, front |
| 6 | Pushing the disc (no lag) | Front, behind |
| 7 | Poor sequence timing | Side, front |
| 8 | Poor wrist lag and acceleration | Behind, front |
| 9 | Poor weight transfer | Side, behind |
| 10 | Poor finish and balance | Side, front, behind |
For the basics of the throw itself, start with disc golf forehand basics.
1. Poor lower body load
The legs do not load before the throw, so the forehand becomes an arm-and-shoulder flick. Check: from the side, before the forward move, is there a visible bend and weight set on the back leg?
2. Collapsed / unstable load position
There is a load, but it is wobbly: the torso slumps, the knees cave or the weight drifts. An unstable base makes the arm path unstable too. Check: from the side or front, does your body look still and balanced at the end of the load?
3. Chicken wing (elbow escape)
The throwing elbow flares away from the body and leads the throw, like a wing opening. The disc tends to come out pushed, wobbly and with less spin. Check: from the front or behind. Full guide: fixing the forehand chicken wing.
4. No lower body sequence (arm-initiated)
The arm starts the throw while the hips are still. It is the forehand version of "all arm." Check: from the side or front, which moves first at the start of the forward move, the hips or the hand?
5. Losing the compact forehand path
A good forehand keeps the arm fairly close and the path short. When it stretches out wide, the release point wanders and the disc sprays. Check: from behind or in front, how far does the hand travel from the body during the swing?
6. Pushing the disc (no lag)
The disc leads the hand through the swing instead of trailing it, so you push it toward the target rather than snapping it. Check: from the front or behind, just before release, is the disc trailing your hand or out in front of it?
7. Poor sequence timing
The parts are there but in the wrong order or at the wrong speed, for example the hips and shoulders turn together, or the arm fires before the plant. Check: from the side or front, step frame by frame and note the order: front foot, hips, shoulders, arm, wrist.
8. Poor wrist lag and acceleration
The wrist does not stay cocked back until late, so there is no snap at the end. A study of sidearm throwers found that skilled players pronated the forearm (rotated it palm down) before release while unskilled players supinated it (Sasakawa and Sakurai 2008). Check: from behind or in front, slow it down and watch the wrist angle in the last few frames before release.
9. Poor weight transfer
The weight stays back or drifts sideways instead of moving onto the front foot. Check: from the side or behind, where is your weight at release?
10. Poor finish and balance
Same idea as backhand. Check: any angle. A controlled finish usually means the earlier parts were in order.
How the faults connect
Many of these faults are links in the same chain. Classic throwing biomechanics describes a proximal-to-distal sequence: the big segments near the center of the body start the motion and pass speed out to the arm and hand (Putnam 1993). Break an early link and the later ones go wrong too.
| If your video shows | Look earlier for |
|---|---|
| Rounding or losing the power pocket | Early upper body rotation, arm starting first, poor loading sequence |
| Chicken wing or pushing the disc | Arm-initiated throw, collapsed load |
| Poor finish and balance | Weak brace, poor plant timing, incomplete weight transfer |
| Early rotation | Poor plant timing, poor loading sequence |
The practical rule: fix the earliest fault in the throw first.
How to work through the list
- Film two angles, side plus behind or front.
- Pause on five frames: end of load or reach-back, front foot landing, disc passing the chest, release, finish.
- Pick one fault, the earliest one that shows clearly.
- Drill it slowly and review your clips in batches. Motor learning research suggests constant feedback can make a skill harder to keep once the feedback is gone (Anderson et al. 2005).
- Re-film from the same spot and compare.
A 3D form analysis makes step 5 easier. Once a throw is a 3D body, you can view it from any angle, including straight above, so a side-on clip can still show you a sideways fault in the rebuilt view, and you can line up an old and a new throw side by side synced at release.

Questions
What is the most common disc golf form mistake?
Coaches most often point to the arm starting the throw before the lower body, which shows up as rounding on backhand and as an arm-initiated throw on forehand. We have not published data on how often each fault occurs, so treat that as coaching consensus, not a measured ranking.
Which camera angle shows the most disc golf form faults?
Side-on shows the most, including posture, plant timing, weight transfer and early rotation. Behind or in front of you is needed for faults that move sideways, like rounding on backhand and chicken wing on forehand. Filming two angles covers almost everything.
How many form faults should I work on at once?
One. Many faults are linked, so fixing the earliest one in the throw often cleans up later ones. Pick the fault that shows up most on your video, drill it at low effort, and re-film before moving on.
Are backhand and forehand form mistakes the same?
Some ideas carry over, such as loading the legs, sequencing from the ground up and finishing balanced. The arm faults differ: backhand players tend to round the pull, while forehand players tend to let the elbow escape or push the disc without wrist lag.
Can an app find my disc golf form mistakes?
Disc Golf Form Analyzer tracks your body frame by frame on a phone video and grades a backhand or forehand against a real coach's ideal form on these 20 faults, only checking the ones your camera angle can show. Disclosure: we make it.
