I had an old injury with torn ankle tendons that kept me from running, since I'd always get some pain after a few minutes. I wasn't sure if HEM would work for me, but it was amazing. Within about a week, I noticed that I could run without any pain for a few miles. Sure, it felt a little sore the next day, but I kept at it. Now, it's 3 weeks since I started HEM and I'm trail running again, one of my favorite things to do! No pain or soreness afterward! I couldn't be happier with the results I got. Thank you!
