It's not the time in the saddle. It's everything around it.
Bent over picking out feet. Twisting to do up girths. Lifting saddles on and off the rack. Hauling feed, mucking out stable after stable. Then holding yourself steady for an hour while a half-tonne animal moves underneath you.
Your lower back takes all of it. Every single day.
So of course it aches by the evening. That's not weakness, or bad posture, or a weak core. It's a normal back doing a genuinely hard job, over and over.
Here's the part I got wrong for years.
I thought because the soreness was normal, I just had to live with it. Ride, ache, drive home stiff, wake up, do it again. That was the deal.
What I didn't see was where that deal was heading.
Because carried home every night, it stops being soreness. It's dreading the drive. Snapping at people because your back's screaming. Sitting out the second ride because you're not sure your body's up to it. And the quiet one nobody says out loud — wondering how many good years you've got left in the saddle.
Your back isn't broken. Mine wasn't either. But "pushing through" isn't free — it just moves the cost somewhere you don't notice until later.
Being tough got me this far. It wasn't going to get me the rest of the way.
So I went looking for something that would fix it.
