Perfect Form for the Ball Squat

Here’s a simple guide for doing an exercise ball wall squat:

  1. Stand with your feet hip-width away from each other.
  2. Put the exercise ball in between the wall and your lower back.
  3. Settle your hands on your hips and lean against the ball. 
  4. Bend your knees and lower your body. Do this gently and gradually until your thighs are parallel with the floor.
  5. Allow the exercise ball to roll down your back slightly.
  6. Hold for a count of five and push into your heels to return to your primary position. 

For beginners, get into the squat position gradually and get comfortable with this stance before trying to bend your knees all the way. 

It is also recommended that you lower your hips towards the floor, a little at a time, until you know that you can hold the position confidently.

Here are some tips you can follow to ensure  that you are doing the exercise ball wall squats correctly. This can make your form better and your workout more effective. 

  • The exercise ball and your lower back should always be in contact. There should always be a portion of the ball that’s always connected to your back.
  • Always keep your eyes forward and your weight against the exercise ball.
  • Press against the exercise ball when you push into your heels to get back to the original position. This will give you more stability.
  • Keep your feet facing forward when doing the exercise ball wall squats.
  • Don’t allow your knees to roll to your sides. They need to be in line with your body.
  • Adapt the “slowly but surely” method, meaning you don’t have to be doing full squats just yet. You can spend time just keeping your back in contact with the ball and moving forward while ensuring your technique and form are correct. Take it slow.

Exercise Ball Wall Squat vs. Normal Squat: Which is Better?

Choosing between traditional squats and exercise ball wall squats is entirely up to you. Both are effective exercises that target specific parts of your body. 

Performing exercise ball wall squat minimizes the impact on your glutes and hamstring but has a noticeable quadriceps involvement. This exercise is more focused on your knees than the standard squats. But if you have weak knees, then regular squats would be a safer option.

On the other hand, regular squats are best after strengthening your legs, specifically your glutes, hamstrings, and quads. They are considered the “king of leg exercises.” Regular squats are also effective in toning and strengthening your leg muscles, abdomen, and lower back. 

However, you may not be able to do regular squats after an injury as this exercise can be rather stressful to the body. This is where incorporating the exercise ball comes in handy.
