I know as well as anyone not to go into a stretch without a full warm up of the body. As a cheerleader we all have to warm up in order to do most things.
Well I will tell we all know when we drunk we more flexible but sometimes wanna show off or get asked. I have done a few times and then the not warming up caught up with me and I pulled my hamstring on my right. Rested it but it took long. I was higher on my split and still did it on my left and that's my least flexible.
So having to work back down as I lost abut maybe 2 to 3 inches. When my right leg was about half an inch off the floor.
Please please warm up well. I'm speaking from experience. Also if you not sure get a professional to help you whatever your goal.
