Who knew a cheap Pilates ball could totally level up your core workouts? Pilates instructors swear by it for deep core engagement—just squeeze it between your ankles or thighs, or hold it in your hands for upper body moves. It can even make tough exercises easier by supporting your back. Try adding it to classics like the hundred, half roll back, or teaser, and you’ll feel the difference. Seriously, it’s the best under-$10 upgrade for your home workouts! #Fitness #Pilates #FitnessHacks
