Help.. I can't clip in!

[Owlie]

I've used clipless pedals before and I use them 5x per week on my spin bike. I just installed new pedals on my old mountain bike. It's almost impossible to clip in, so I can't even imagine how hard it will be to clip out!

I've adjusted the float in the pedal to the loosest setting and even switched my cleats to the oldest pair I have (hoping some wear and tear would make them looser).

It's almost like I can't generate enough force to clip in and down - I'm only 100lbs - but that shouldn't matter. What on earth am I doing wrong? I even tried taking the pedal off and trying to get my shoe into the pedal, and I can't do it! Am I just a total weakling??

Any advice or similar experiences?? Thanks!!!

Pixie: What kind of pedals are you using?

Check 3 times more that you've adjusted them to the loosest setting.

Then snap a photo of the setting and the cleats and post here.
