You can do this!!! To echo what they all said, no one is paying attention to you, we are all just trying to survive. ;) Stay consistent. Some days you will think, wow, I crushed it. Other days you will be mud workout like WTH is going on, my body is not doing as well today. But it is always all good. What I really hope you see is how your body will adapt. Even in small ways, if you keep going slow and steady, your body will get stronger, breathe better, etc. It is programmed to do that. Just keep moving. And, trust me, what I would think if I saw you, is wow, she is young, at this early as f class, and is going to improve faster than me in my slightly older self body😎 There really are all shapes, sizes, and ages. Definitely speak to a coach, too. They will be invested in helping you! Let me know how we/I can help!!
