Throw the stick!!!!
Some people point their toes down throughout their stroke. I am one of them.

- Keep your head up.
- Don't tense your shoulders so much.
- Bend your elbows.
- The bouncing in your upper body is a symptom of a jerky stroke. Work to smooth that out.

Have you been doing any one leg drills or high cadence drills? They can really help you smooth out your spin.

It would help if you would slow down as in this one.

I think this is your main problem. I love the optimism though.

With your toes pointed down throughout the stroke like that, it will make your saddle seem lower. Try flattening your foot near the bottom of the pedal stroke and you'll get a little more leg extension without raising your seat. Also, try to get a shot from head-on so we can see your knee tracking.

There's a reason I mentioned knee tracking. When you keep your toes pointed down, you are actually flexing the ankle throughout the pedal stroke. Since the ankle's two joints are not perfectly square to the body's major axes, this causes torsion in the leg. Since the foot's camber is fixed at the pedal, this force shows up as a lateral wobble at the knee. It's more stressful on hip and knee joints and less efficient.

yeah, you already mentioned your toe-down pedaling.

Proof? Draw a freaking vector diagram starting at the hip and work your way down.
404, bottom of pedal stroke not found. His left leg is already beginning an upstroke and his right leg is exactly where it should be. Notice the constant 90 angle in the ankle joint.
Quite a few very successful riders (including some Lance guy) pedal toe down.

his down foot is flattened. This differs from the OP's video where his feet stay at an almost constant angle to the ground.
