Connect a resistance band to the workout bar and attach the other end to a D-ring on an ankle strap. Do the same for a pair of resistance bands. Position feet under the workout bar with very wide stance. Squat down and grab the bar between legs with shoulder width or slightly narrower mixed grip.
Lift the bar by extending hips andknees to full extension. Pull shoulders back at top of lift if rounded. Return and repeat.
Knees should point same direction as feet throughout movement. Add difficulty by triple, or quadruple the resistance bands through the holes under the workout bar and the D-rings on the ankle straps.
