Stability Ball Knee Ins From Plank Position
Best Stomach Exercises for Women and Men

Learn all the best stomach exercises for women and men.

The Stability Ball is a very popular tool for core exercises and stomach exercises.

Below are 2 variations of the plank exercise, utilizing a stability ball.

Plank Position Straight Knee Ins on a Stability Ball

You can do this exercise from your elbows or your hands. Each one offers slightly different core muscle work, balance challenge, and range of motion. Try them both and use the one you like better.

Starting Position: Begin in a plank position with your hands in a comfortable position on the Stability Ball. Engage your abs, so that your back is in good alignment.

Form: While keeping your abs and core tight, bring one knee in straight in towards the same elbow, and try to touch your elbow with your knee. Hold for a brief second and then slowly lower to the starting position.

Personal Trainer Tips: You can do this stomach exercise in alternating fashion or you can focus on one leg at a time.

It is very important to be mindful of the position of your lower back during this exercise. If you feel your lower back arching excessively, think about engaging your abs or take a break and rest for a moment.

Elbows on the Stability Ball

When the elbows are on the Stability Ball, you will have a little more tension on the abs because you will be more horizontal to gravity. You will also likely feel less range of motion in the hip when the elbows are on the Stability Ball, but still attempt to touch your opposite knee to your elbow.

Key Point: Really push to try to touch your knee to your elbow. If you only use partial range of motion the exercise will be less effective. Move in a slow and controlled manner and focus on keeping your core and lower back stable.

Note: These are really advanced stomach exercises. First master the regular plank on the floor, and then master holding the plank with your elbows on the ball or practice the plank while placing your hands on the ball.

Once you have mastered those first 2 progressions, then attempt to add knee ins to the plank when your hands or elbows are on the ball.


Often, men and women choose different exercises for their core, but the best stomach exercises for women are also the best stomach exercises for men.
