Military Muscle: In the studio with a pyramid workout and Marine Sgt. Stephen Houserman

The next Military Muscle workout is only three exercises, but it’s going to kick your butt.

Demonstrating Bob Thomas’ pyramid workout is Marine Corps Reserve Sgt. Stephen Houserman, 23, a power lifter and this summer’s intern at Marine Corps Times. Houserman dropped 40 pounds in two and a half months to be eligible to enlist.
