complete beginner, bad fitness, but super happy about my third time on this public trail

I wish I discovered this sport earlier. I just started riding 2 weeks ago with absolutely 0 cardio at 30yrs old and a bit overweight and I feel progress every ride. I almost ride everyday, I love it! Third time on a trail and every root is a challenge 😂
just wanna share as I don't know anyone who does this sport
