Lifting Diagrams for Beginners

Hi all,
In the past I have used the following website when needing to checkup on the form of an exercise, particularly if I was totally unfamiliar with a new exercise. This site is great, not only does it give detailed information on each muscle group but also animated gifs showing the appropriate exercises.
Thought this would be useful for beginners (and couldn't find the link anywhere in the forums).

Particularly check out the 'Articulations' and 'Exercise and Muscle Directory'

Cheers,
Jaye
