A Pilates teacher says you can encourage deep core engagement in your workouts with the addition of this cheap tool

A woman exercises at home an a mat. She is on her back, propped up on her elbows, legs elevated, knees bent and a small Pilates ball held between her feet. There is a kettlebell and water bottle near the mat and in the background we see a couch and leafy plant.

Pilates balls look like unassuming little tools, but they can take your workout to the next level.

“A Pilates ball can either support the body or intensify the work, depending on how it’s used,” explains James Shaw, a Pilates instructor.
