im interested to know these stretches you speak of! :)
Haha sure enough. I will try this again. My internet randomly shut down, and I was so close to the end. Okay there are three stretches.
1- Standing facing the horses withers. Take both hands and place them where the girth lies under his stomach. Start to "tickle" the area and you should immediately notice him life his back up. Once he has slide your hand, the one closest to the hind end, towards his sheath area and stop about 6ins before. I know it on my horse where he has a cow lick of hair. "tickle that spot to make him hold the lift on his on. Do it for 30 seconds and release. Do them in reps of 30. As your horse starts to gain muscle you can add on seconds to the reps, I do it in increments of 10. Over all he should look like he's arching his back up, just make sure he isn't leaning on your hands, but using his stomach and you will be able to feel the difference.
2- Stand behind the horse, if you are worried he might kick stand parallel to his hind leg. Place each hand on either side of his hip bone at the top of his rump ( ie, Sacroiliac area) "Tickle" him there as well and slowly slide your hands down so that each hand is on one side of his tail on his hind-end (butt area). Hold it for 30 seconds and release. Do it in reps of 3 and also add seconds like above as muscle builds. He should tuck his butt under him as he does this stretch and lift his lower back.
3 - I always end with a carrot stretch to loosen all the muscles I just worked. This one is pretty simple, take a treat, carrot, grain, etc and starting on the left side coax his head to stretch and reach his stomach with the treat. Hold it for 15 seconds and release. Switch to the other side and do the same process. Do each side three times alternating. This will also relax his next muscle and encourage him to go long and low to help build that top line as well.
Like I said I have seen a significant difference within a month for many horses and sometimes it may even take 2 months depending on how much he has already. But for him to really use that top line, the hind end, stomach and neck also need to be relaxed and muscled!!
Good luck and let me know if you have any questions!
