If you're older, haven't exercised for some time or have health problems, it's a good idea to check with your doctor before starting any new exercise program. Pilates is no exception. Similarly, women who are pregnant should check with their health care providers before starting Pilates or other exercise programs.
Pilates can be adapted to provide a gentle strength training and stability program, or it can be modified to give a seasoned athlete a challenging workout. If you're just starting out, it's a good idea to go slow at first and gradually increase the intensity of your workout.
Let your instructor know if you have any conditions or previous injuries so he or she can assist you in modifying movements.
Because it's essential to maintain the correct form to get the most benefit — and to avoid injuries — beginners should start out under the supervision of an experienced Pilates instructor.
