Learning to do something new takes time, and practice makes progress. The more time you put towards Pilates the sooner it can benefit you.
Many exercises can be done while brushing your teeth, sitting in traffic or doing the dishes. As much as we all want to push the river and feel better, stronger and more flexible now, change that lasts happens because of continued practice. This approach means you can progress organically, without catastrophic injuries, or even really inconvenient ones.
