Kuri,
Among the ones I use most:
Squat (bottom iso-metric hold)
Push-up (3 positions: top, middle, bottom)
Lunges (bottom hold)
Chins/Pullups (top middle bottom)
Shrugs (top)
Bench (variety of positions)
Most of the bodyweight isometrics are done with the young athletes. Mostly b/c as Bill said, many people, and particularly these athletes, have no control of the trunk. The iso's help strengthen the movement and control of the trunk.
Overall, my approach and the situations I use the isometrics are probably different than CT.
