A common exercise prescribed by our therapists as well as in our Pilates class is: The Bridge.
The Bridge is an excellent stability exercise. This means that one of your goals is to keep your pelvis very still during the exercise. This exercise strengthens the gluteals and the lower abdominals promoting core stability.
It’s a safe exercise for those with a weak or injured back which starts at a low level but can be progressed as control allows into a high level stability exercise.
