Start with feet together. Step back with your right leg, bending both knees, and hold. Extend your right arm over your head, left arm straight down next to your left hip. Make sure your left knee is over your ankle, right knee under your hip. Level your hips and keep your spine long. As you stand, draw your right knee into your chest, keeping your spine still, and switch your arms so you left arm is extended and your right arm drops. Step back into your lunge and switch your arms again. Repeat on opposite side.
Do: 60 seconds on right side, 60 seconds on left side
Benefits: The movement is great for the core and glutes. The arm movement will help build core strength along with triceps and shoulder strength.
