Watch the Guide, Pivot and Repeat online guitar lesson by Brad Carlton from Chord Studies: Inversions Vol. 1
This four bar progression moves from D Minor to C, and then from C back to D Minor. We start on the second, third, and fourth strings for the first two measures, then we switch over to the third, fourth, and fifth strings, for the last two chords. Be sure you are utilizing your second finger as a guide finger when you change from the first to the second chord, and as a pivot finger when changing between the third and fourth chords.
