The lack of spirituality certainly doesn’t take away from the effectiveness of Pilates. Its main objective is core strengthening, requiring intense concentration and breathing techniques. Workouts tend to run in the 45-90-minute range, with 5-10 reps per exercise, incorporating precise ranges of motion, rhythm, and breathing. Like yoga, it can help improve muscular and postural strength, but because of the focus on the core has the added benefit of toning abdominals more quickly. Although it is more active than yoga, muscles are never worked to exhaustion and Pilates lengthens and stretches all of your major muscle groups in a balanced way.
