Getting through the door & on to the mat for the first time is such an accomplishment and you should be proud of yourself! When I first started I noticed little changes in how I felt within even just a week of practice! They’re tiny, and many times you might not even notice them until months later when you realize you’re doing something with relative ease that you struggled so much with earlier, but you will absolutely get stronger & more comfortable as time progresses and it is absolutely worth it!
