Epic is a 2008 Thoroughbred mare, retired from racing in 2013. I worked on her for the first time about a year ago at Grey Goose Farm in St. Johns Florida. Massage sessions aren't always about finding and treating trigger points within the muscle structure. Sometimes it's a way to help a naturally nervous horse relax, both physically and mentally.
In order to build muscle during your horse's training, many small tears are made in the muscle fibers which are then fused back together to form new muscle protein strands -- this process happens after a exercise or training not during.
