Pause at the bottom position for a 1sec count while squeezing your abdominals.
Maintain the neutral position of your back as you squeeze your abdominals to rotate your shoulders to the left. Your feet should not touch the ground and remember to breathe throughout the entire movement.
Repeat steps 1 through 4 until you have completed the desired number of plate twist repetitions before resting your feet on the ground.
This completes one set of plate twist.
