Russian Twist
Russian Twist strengthens your core, obliques, and spine. It's a total core exercise that also works your balance, builds stability in your spine, and trims your mid-section all at once.
INTERMEDIATE
Single-Leg Flex And Extend
Single-Leg Flex And Extend is a good core and lower body exercise. This movement targets your glutes, hamstrings, and shoulders as well as provides mobility to the hips.
Instructions
- Start in a push-up position with your hands shoulder-width apart. Your body should form a straight line from your shoulders to your toes.
- Lift one leg off the floor, bend your back and bring your knee up to your nose. Pause for a second.
- Reverse the movement by extending your leg back without placing your foot on the floor. Release your hips and pull your chest up. Then return to the starting position.
Tips
- Do not bend or lower your hips into the starting position.
- As you lean back, squeeze your buttocks to stabilize your torso.
