Check out the two great pre/post natal pilates workouts below. Both are also great for runners, hypermobile individuals and people looking for a core workout. It's important to listen to the instructions and get a qualified health professional or pilates instructor to look at your technique.
The workouts here are also an excellent accompaniment to a running program. Long distance running relies on a strong Gluteis Medius and we really target this muscle here. I would recommend trying to complete these workouts twice a week alongside your running.
