Trouble running...not because of legs though

Are you keeping good posture when you run? Standing up straight, not bending over at the waist? Keeping your shoulders down, arms loose at your side? Not pumping with your arms for momentum and tensing up? Keeping your head up and looking ahead not staring down at your feet?

Any of those things will cause pain for any runner. Posture is a critical part of running.

I'm not a runner, so I don't know if my idea is valid. But I've seen bras that are designed to assist with posture. Or even the back braces that people who work with heavy objects use on their jobs. Would something like that help?

Or maybe, do some strength exercises to build muscle in that area, maybe it's a muscle weakness that's causing fatigue that leads to pain?

I agree on core strengthening exercises. When I started running I was surprised to find how much it whittled my middle. Running takes core strength. Because of your body type you might just want to do some ab and core work before, or while, you build up miles. And good for you for trying I out!

^^^ This +100. Excellent advice.

Also step lightly, mid foot plants & not hard heel strikes....think about going to a minimalist shoe (slowly). Dont worry about speed or how silly you imagine you look to others, but enjoy the experience, look around you, relax & check out the scenery, (ah damn I need to run lol)....remember, step lightly, relax, enjoy & work on your core.

A couple things may be at play or at least working on them will help. Posture is a big thing. We think we're fine until something hurts or somebody points something out. You don't want to really be bent over as you run and don't need to bring your legs too far forward. Concentrate on posture. It may mean you fatigue differently at first because your body is getting used to this new position. How are your feet landing? You want to heel strike as little as possible. A nice midfoot strike will suit you well. When you heel strike the shock goes straight up your body. Do you have good shoes which are properly fitted to your foot? What about your gait? It wouldn't hurt to go to a runner's store and have them check your gait vs what shoes you have. If you're overweight I would recommend against minimalist shoes. They don't have the cushioning and you'll be hurting and miserable even as you get used to them. When you slim down to an acceptable weight and become proficient in running, then you should look at minimalist running. Sports bras.... well... I'm a guy. You're on your own with this one. I would suggest checking with sports stores and different companies to see what they have to offer. One may help you more than another.

First let me state that I am not trying to argue or embarrass anyone. Runners need to stick together and help each other; but I disagree and the facts support me.

Running minimalist forces you to stride & foot plant the correct way. I promise, you wont heel strike but once while running barefoot or minimalist...lol! Oh yeah, trust me on this.

Control running shoes weaken our feet and force us to run in an unnatural manner. Barefoot or minimalist running nurtures our natural running style. Our feet are designed to roll and flex, the arch is suppose to act as does the leaf spring in a car....pronation and supination are natural dynamics. Over pronation is a result of weak arches, dont get arch supports, strengthen the feet by walking every chance you get without shoes. Engineered running shoes nurture dependance on them.

I had to laid off running for 2 years and I currently weigh 238#. I have 3 pair of Asics Kayano, 2 being brand new. Kayano is designed for the big runner. I have had issues for years with shin splints.

2-3 weeks ago on a lark I bought a pair of New Balance Minimus & hit the road & damn did my feet ache. I went easy, rested, and my feet quit hurting and not one issue from the shins! Ive run 4-5 days this past week, twice in excess of 1 hour & cant quit smiling.

I hope you try running minimalist. Your feet will ache at first so ease into it, but give it an honest effort. You will be happy with the results.

I agree with the others, core strength is a big part of running. Your legs are moving, but what is supporting the rest of you? Core training/ upper body strength training will help a lot with this. Good Luck.
