Moves around when peddling
The pedal exerciser looks as if it would be sturdy enough to be stable when in use.  It has rubber extensions on the legs and I had hoped it would grip the floor.  It does not.  I tried it on hardwood and when that didn't work I put a rubber backed piece of carpet under it.  Neither worked. It  jumped all over the floor, so then I put it against a door frame and it didn't jump around as much, but it still moved too much to be useful.  Finally I butted the entire width of the front of the exerciser up against my raised fireplace hearth and I was able to use it.
