Pilates exercises are part of a fitness method started by Joseph Pilates in the early 1900s. This popular workout trend teaches awareness of breathing while focusing on the alignment of the spine. Pilates target back and abdominal -- or "core" muscles -- but is also effective for toning the legs, arms, shoulders and glutes.

The exercises are often performed on a piece of equipment called a reformer, but can also be done on a mat without equipment. During these Pilates classes, you'll perform non-weight bearing moves that use your body weight to tone your muscles. All Pilates exercises have numerous benefits, including increasing both strength and flexibility, while also improving lung capacity.

Pilates classes are available at most gyms. Still, finding the right instructor can be the key to success. Certified instructors will give clear and precises directions that focus on correct body positioning and breathing. It's the instructor's job to accurately demonstrate the exercises for you and to give you cues that make the movements easy to understand.

Pilates exercises are great for both beginners and advanced exercisers. Instructors should provide modifications for the exercises and offer some individual instruction to ensure you are performing the moves in a way that is both safe and effective. Injured students should be able to participate with these modifications, too.
