Circuit 1, Exercise 3: Kneeling Core Twist and Press
Start kneeling on your left knee with your right foot out in front, your right thigh parallel to the floor. Your right knee should be over your right ankle and your left knee directly under your hip with both knees bent at a 90-degree angle. (If you need extra cushioning on your left knee, grab a mat or a towel.) Hold one dumbbell at your collarbone, holding it horizontally in both hands, and pull your core in toward your spine.
Brace your core as you twist your torso towards the right while simultaneously pressing the dumbbell overhead with both hands. Start the movement from your core, keeping your hips facing forward and tucked under your torso. Make sure to pull your abs tight throughout the movement.
Lower the weight with control as you twist your torso back to the starting position.
This counts as one rep. Complete 10 reps on each side.
