Pilates has been long-hailed for its ability to produce long, lean muscles without causing bulky muscles. This is because the exercises are performed at a lower resistance for a longer and slower amount of time than traditional “strength” exercises at the gym. Strength training (eg low reps, high resistance) brings about hypertrophy and bulking within the muscle fibres. Pilates also uses deep AND superficial muscle systems to achieve a more balanced musculature.
