I have MS, and I was WEAK when I started re-riding after three years of riding once a year.
When I found my lesson stable they did not have a very stable mounting “block”. Luckily the horse I was riding was a saint, very spirited but at the same time patient if I did not hurt him.
Then I discovered the 3 step mounting blocks. I saved up my money, bought one, got it to the stable and told my teacher it was my donation to her riding school. I find it so much easier to mount from the 3 step, especially when my MS is messing up my body.
I get a kick out of seeing the little, little kids being able to get up on their lesson horses without dragging on the saddle. The kids are happier, the horses are happier, my riding teacher is happier, win, win, win!
The cost averages out over the years, and the fact that your body has less wear and tear is simply priceless, especially with what medical care costs nowadays.
