Congrats! This is awesome. As someone who was in this place a few years back, I can honestly say that your future self will thank you for sticking with this.
About 5 years ago, I started working out consistently, and it's the best thing I've done for myself in a really long time. Once it became a habit, I missed working out if I couldn't make it for a few days. I crave it now. I am in my mid-forties now, but I'm fitter than I was for most of my thirties, and I have more energy for things.
So great job for getting active again, and stick with it! You will be so happy you did.
