Lower back seizes up when running.

Hi, can anyone plz help me? Have just started road running over the last year and have done a couple of 10k s. My problem is that most times when i am running my lower back seizes up and i have 2 walk for a couple of mins until it comes round. I have no trouble when running on a treadmill and i cycle and do Karate so i am active enof. I wear proper running shoes and keep my head up when i run. PLZ CAN SOMEONE HELP...

How are ur core muscles? I would think ur imbalanced, strengthening ur core will make a major difference in how u carry urself while running. Also get off the roads, they will tear u apart...... this is a "trail" forum site.

totally on-board with the last response. Strong core most definitely supports a healthy back and trails are darn sure the place to be. Might also want to consider looking at other parts of your life that might be setting you up for a seized up back on your runs...too much time sitting at a desk? posture? activities that cause strain? too much stress? Good to look at the whole picture...

Totally agree with the strengthening of the core. Also you may need to work on your flexibility. I did karate for many years and was strong and flexible but not where I needed to be for other sports. Maybe you are too tense. I was and it took a while to loosen up whilst running.

A good exercise for your lower back is the "good morning." Here is video of the technique: http://www.youtube.com/watch?v=bUpOZnhS4FI&NR=1. I am not a fan of lifting weights but I use this as well as a few others to help keep a balanced core. I highly recommend starting out really light.
