Why Do I Keep Pulling My Hamstring?


I am a high school level sprinter and I keep pulling my right hamstring as I hit about 30m in the 100m dash. It has happened twice in the last month. I don’t know why this keeps happening, as I worked a tremendous amount in strengthening my hamstrings over the past year. I have been doing Nordic curls and Romanian deadlifts at a very heavy weight, and my hamstring strength has increased tremendously but nothing seems to be preventing these injuries. Also, I noticed that my right foot always seems to turn out until it is perpendicular to my left whenever I suffer a pull. Why is this happening to me and what can I do to stop it?


I thought I had this problem…it turned out that I had a herniated L4 disc. that was pushing on the nerve that senses my hamstring. I was sprinting when it happened, basically sprinting caused the disc to pop out.

Go to a physical therapist.

Or do 15 reps of the seal stretch (aka press-ups) every 2-3 hrs a day and see if it gets better. Do this stretch when you wake up and before bed (for a total of 8 stretch sessions/day). Also focus on your posture, stay upright and don’t slouch cause this can make it worse (if this is your problem).

but don’t take it from a guy on the internet…go to a Physical therapist


Definitely second the advice to go see a Physio.

IME, most muscle pulls are due to a lack of mobility, not strength. If you have been doing a lot of intense strength work and little to no mobility/flexibility work, then there is a good chance that your strength and mobility have gotten out of balance. Your hamstrings have become, for lack of a better word “brittle.”

So, I would highly recommend investing some serious time doing some dedicated flexibility work (IME you need to hold Stretches for a minimum of 1 minute, 90 seconds to 2 minutes is even better, for you to gain noticeable ROM), and I would recommend adding in some mobility work into your strength training sessions.

Hope this helps. Good luck.
