Yup, looks like lunges are a good all over exercise. Maybe I should use them as my main exercise and finish off the hams with the isolated machine. They bother me a little though, usually feel like my knees are weakening.

Speaking of which, I should probably mention that my joints popped a little today during my workout. Not painful, just annoying. Mainly in my elbow during tricep extensions. More stretches are probably in order, I assume.
