You are leaning backwards slightly during release.
Possible Fix:
A common cause of anhyzer tendency is an off-balance pull and follow-through. If you are leaned backwards or on your heels during your whip there will be a natural tendency to jerk the outter edge of the disc upwards resulting in an anhyzer release. Making sure you are balanced and on the balls of your feet should help fix this but you may also want to consider the angle of your back.
You have the disc too far out from your body during your pull-through.
Possible Fix:
Having the disc close to your body during your throw is necessary for maximum power and snap. If you get your arm too far away from your body it will slow your body rotation and rob you of power, but more importantly it gives a tendency to pull the outter edge of the disc resulting in an anhyzer tendency.
You are rolling your wrist over during release.
Possible Fix:
Wrist roll is your tendency to turn your wrist/forearm during or immediately after release. This usually happens when your arm is moving very fast so it might be a tough one to spot. If you go through your motion in slow-motion, open your hand like you are going to shake hands with someone. On a release with no wrist roll your palm should be facing somewhat towards you. This is ideal for a line drive shot. If your palm is facing up, you are rolling your wrist over. The result of this is that discs are more likely to turn over and may cause anhyzer tendency. The timing and magnitude of the roll will effect the flight and severe early wrist rolls can lead to grip lock or unintentional rollers. Wrist roll over is often used on a throw like a roll curve, but it won't work as well for a straight throw. On the other end of things, rolling the wrist too far under is shown with the palm facing down. This will expose the flight plate and give a very hard hyzer.
You have the nose of the disc too far down.
Possible Fix:
This is usually not that severe a problem but it might cause undesired turnover. The most critical angle for nose down is during the disc pivot. Do a slow motion throw and pay attention to the back end of the disc through your throw. If the back edge is much higher than the front, you might want to lower it a bit. The farther the nose down, the easier it is to have a disc flip or incidental anhyzer frm the release point.
You have improper disc orientation and/or disc pivot angle.
Possible Fix:
Disc pivot is a tricky one to explain but I will do my best. Newer players often think that the disc will leave your hand exactly as it is at the point of release. This is true if you are letting go of the disc, but a correct grip and throw will have the disc ripping out of your hand by pivoting off between your last finger on the rim and your thumb. You can simulate this by holding the disc with your grip and pulling it slowly out of your hand. Pause at the last place you find your hand touching and that is your disc pivot point. Notice how the disc lurches a little upwards and to the left. If you hold the disc without any hyzer/anhyzer angle and the nose down as it enters the pivot, the resulting up/left lurch will shift the disc into an anhyzer angle upon release. To have the disc pivot off flat nose-down angle, you will want to orient the disc with a slight hyzer angle. You can experiment with angle by simulating a disc pivot and with a little practice you should be able to find the angle that works best for you to have the disc release flat or hyzer.
