First, let me apologize for all of my posts recently. I feel like I've been posting these stupid little questions all over the place. I'm having a hard time finding previous threads with answers/information that I'm looking for.
If I'm lunging my mare with side reins on, what am I doing to/for her?
What I'm wanting to do is build up her topline (I'm doing other exercises as well, hill work and tons of trotting)
I'm kind of worried that she's not using her back and butt, no matter what I do. A few times today I saw her using her back.
I'm worried that I'm going to mess her up and really set us back.
Should I, or should I not, use side reins to help her build up some muscle?
