American Hammer

A more appropriate name for the former Russian Twist. Rocky did beat the Russian in the movie. Sounds tougher too...

While on six in partial sit up position with heals just off the ground, twist at the waist so that both hands held together almost touch the ground beside your waist, alternating in cadence from side to side. Often times done with bricks in hand.

AKA Zelensky Twist or Russian Twist
