Full disclosure, I love both pilates and yoga and teach both disciplines. There are so many similarities between yoga and pilates and even some of the exercises (poses) are the same but here is the real deal.
Yoga includes a meditative component in the practice. Whether you chose hot yoga, a vinyasa flow yoga or a restorative yoga class you will enjoy a “savasana” towards the end of the class (my favourite part).
Pilates is a form of strength training focusing on the core. The core includes everything from your shoulders to your pelvis. Some props such as stability balls, weighted balls, pilates circles, foam rollers can be used to challenge or assist the body during the workout.
Both yoga and pilates will build strength, improve flexibility and balance. These practices are both considered mind/body with a strong focus on breathing and alignment.
Things to consider...
Osteoporosis is a condition in which one or more of your bones has lower than optimal density. To improve on bone density working with resistance is recommended and the pilates reformer is a good choice. Keep in mind that the spine needs to remain in a neutral position avoiding any flexion. Spinal extension (such as swan in pilates or cobra in yoga) is recommended. Let your instructor know of this condition so modifications can be offered. Jump board in pilates is also a good option as it is easy on the joints and is weight bearing.
For weight loss chose a flow style class to increase your heart rate and break a sweat. Both pilates and yoga can be done in a flow style. It is important to include a form of cardio in your fitness plan to burn calories and improve your cardiovascular health.
If hypermobility is your issue focus on strength building aiming for a 3.1 ratio between strength and flexibility training. Be cautious with hot yoga as it can permit stretch to go further than what is safe for you.
Namaste!
