Bosu Ball Step Up Variations

Now that you have learned about the basics of the Bosu ball let’s go over the 7 best ways that you can turn a simple exercise, such as the step up, into a great workout. 

Bosu Ball Step Ups, Blue Side Up with a Knee Drive

To complete knee drives on a Bosu Ball, begin with the flat side on the ground and the dome facing upwards. Place your right foot on the Bosu ball and bend into a lunge, keeping your weight in your right foot.

As you rise to a standing position, lift your left knee as high as you can towards your chest and hold for two seconds before lowering back into a lunge position. 

Remove your right foot from the Bosu ball and return to a standing position with your feet hip-width apart. Complete one set of reps, then switch feet. This time place your left foot on the Bosu ball and bring your right knee up to your chest. Complete the same number of reps on both sides.

Step-ups Black Side Up with a Single Leg Balance

If you’re a beginner to the Bosu ball, you may want to begin with the blue side facing up and progress to the black side as your strength and stability increase.

To complete the exercise, place your right foot directly in the center of the black side of the Bosu ball. Move your foot around on the ball to find the best foot placement before raising your left knee. Your knee does not need to rise above hip height.

When you begin this exercise, start with a simple step up and down to the same spot on the floor. As you progress, begin to hold your one-legged posture on top of the Bosu ball for longer periods.

Step-ups to a High March and a Pallof Press

The Pallof press works to strengthen your abs and core while helping to prevent lower back pain and injuries. The Pallof press uses an anti-rotation action that prevents the spine from being thrown out of its safe position through unnatural twists and bends.

During the Pallof press, the lifter holds the medicine ball in front of them and slowly presses it out and back.

To combine the exercise with a high march, begin with the Bosu ball black side down and your feet shoulder-width apart. Hold your medicine ball at chest height.

Step onto the Bosu ball with your right foot towards the center, lift your left knee into your chest and as you do this, push the medicine ball out in front of you at chest height.

Bring the medicine ball or resistance band back into your chest and step your left leg down to the floor, followed by your right leg. Repeat on the opposite side.

Step-Ups With A Kettlebell Press

Begin with the Bosu ball black side down and your feet shoulder-width apart. Step your right foot onto the dome, followed by your left foot. Bend your knees to a 45-degree angle, with arms extended down in front of you.

Lift the kettlebell in your right hand towards your shoulder and lower. Then, lift the kettlebell in your left hand towards your shoulder and lower. Finally, lift both kettlebells towards your shoulders simultaneously and lower.

Step off the Bosu ball with your right foot followed by your left foot, then repeat on the other side.

Step-Ups To A Single-Leg Romanian Deadlift on a Bosu Ball

A single-leg Romanian deadlift increases your hip, hamstring, and ankle strength and stabilization. Begin with the black side of the Bosu ball facing upwards and the dome side on the floor. Hold a weight in your left hand. 

Place your right foot in the center of the Bosu ball and step up, allowing your left foot to hover in the air behind you. Keep your shoulders back as you bend at the hips to bring the upper half of your body parallel to the ground and extend your back leg out at a 90-degree angle.

Allow your weighted arm to reach the floor and hold your position while stabilizing your core muscles.

Raise your body and lower your back leg to the floor. Step off the Bosu ball and complete the exercise on the opposite side.

Step Ups with Weights to an Overhead Press

Begin with your Bosu ball blue side up, flat side to the floor. Holding a weight in each hand, step your right foot onto the centre of the Bosu ball. Push your weight into your right foot as you raise your left foot and allow it to hover behind you.

As you stabilize your core, lift both weights above your head and hold for two seconds before returning your arms to your sides and stepping off the Bosu ball. Repeat the exercise alternating between left foot first and right foot first.

Step Ups with Resistance Band Hip Abduction

With blue side up on your Bosu ball, step both feet onto the dome with knees straight but a soft flex in the joint. Raise your arms at either side of your body to parallel to the floor.

Gently raise your right leg at a 45-degree angle to the side of your body towards your extended arm. Lower your right leg and repeat the same stretch with your left leg.
