The short answer is: absolutely.

Pilates will increase your internal core strength and give you a greater range of motion in your joints. Your core strength acts like the foundation of a building. The stronger your foundation, the more weight you can carry. The further you can safely move a joint, the more muscle you will use for the exercise. If you can carry more weight, for more reps, using more muscle your body has no choice but to get stronger. This means that not only will you be stronger and more flexible in the gym, but you’ll have functional strength that you will be able to use out in the real world, anyplace, anytime.
