Step by step instructions
Grab a pair of dumbbells and stand behind a step. Place right foot flat on the center of the step and lower down into a squat, holding weights in front of shoulders, palms facing in.
Extend legs, bringing left foot into right on top of step as you bring arms back into a row, squeezing shoulders together. Return to starting position and repeat. Do all reps on the right, then repeat on the left to complete one set.
