A Pilates ball may look simple, but choosing the wrong one can seriously limit your results. Size, firmness, and material quality all influence balance, muscle activation, and joint safety. According to fitness professionals, an under-inflated or poor-quality ball can reduce core engagement by up to 30% during stability exercises.
Stay with me the right choice can completely change how effective (and comfortable) your workouts feel.
