Mastering Stability

Proper selection of the appropriate exercise ball size is crucial for effective performance of stability ball exercises and movements.

I developed this guide to help you select the right stability ball based on my research and experience. I trust my clients to use the gymnic brand, it has a superior quality density with anti-burt technology for the most safety.

Use this simple checklist to make sure you have the right ball:

  1. Start by sitting upright on the exercise ball.
  2. Feet are flat on the floor, and weight is distributed evenly.
  3. Knees and hips are level at about 90°.
  4. The ears, shoulders, and hips are in a vertical line, evenly balanced.

Exercise balls are available in three common diameters, each suitable for individuals with different body compositions. Remember, height isn’t the only factor in determining the right ball size. The recommended maximum weight for this ball is 270 lbs. All stability balls aren’t created equally; the quality of the material greatly affects the size you may need. Luckily, this one is made of heavy-duty vinyl and is latex and phthalate-free for those with certain allergies. Some exercise balls are more flexible and offer different challenges; weight is also an important factor to be aware of. Provided this is the highest quality ball that I know of on the market, you should blow this ball up until it’s hard and round.

Stability balls will naturally lose air pressure over time due to regular use and stretching. As the ball ages, it may need to be reinflated periodically. Every 3–6 months is a great time to inflate your ball to extend its life and durability. However, it's important to avoid overinflating the ball, as this increases the internal pressure on the ball and can lead to tears, rips, and punctures, making balancing and stabilization exercises unnecessarily challenging.
