The iliopsoas is actually two muscles: the psoas and the iliacus. The psoas originates from the vertebrae T-12 vertebrae (the vertebrae where the lowest rib attaches) down to L-4. The iliacus muscle comes from the inside of the hip bone. Once the two merge, they attach to the top of the femur (thigh bone), on the inner surface.

Running with a stroller takes a lot of coordination, balance, and core strength for you. A baby needs to have good head control and some core control. This could be the first time they are facing forward and that can be a very different experience for them. So, here are my tips for stroller running.

Successfully planning for the plan

When it comes to training, I’m the same way. Before creating a training plan I list out the “other” things in my life that will be happening at the same time: work, sleep, general health management, social events…the list could go on. To be sustainable, training has to fit into my life-not the other way around.

Pilates for Life, literally!

I was introduced to Pilates in college. I had two low disc herniation injuries from high school and had to stop running. Someone suggested Pilates to me and not only did I enjoy doing it, but I was able to decrease my pain and return to running. That was when my interest in basic Pilates for rehab started.

To Train Or Not To Train

As the 2020 IN PERSON race calendar essentially no longer exists in the NYC area, running and training look very different right now. While Google can’t help you answer how to run in a global pandemic, some of these considerations may help direct your running goals. First decide whether you want to train for a virtual race, run for fun, or take some time off of running completely. There’s no right or wrong answer here. It’s what works best for you at this time.

Welcome to the Pelvis

“I have hip pain. Well, it’s sorta my hip… or maybe my back too? I’m not sure.” This is a comment that we hear often. Where does the hip start? And the backstop? Is my hip on the front too? What about that side part? Welcome to the pelvis. The pelvis serves as the connection between the body and legs, which is so important for a runner… because you need to use your legs to move your body!

Pregnancy “Planned”

I had 3 goals in 2019: PR a half marathon in May, run the Chicago marathon in October and get pregnant in November. I had a “plan”, so what could possibly go wrong? To kick things off, I went to my gynecologist, who is aware of my RED-S history, and we discussed my plan. Bloodwork showed that my hormone levels were all normal, so there was no reason not to continue with my 2019 plan.

RED-S Book Review: ROAR by Stacy Sims

I have to be honest, I totally judged the book by its cover on this one. There was something about seeing a “perfect” athlete that made me feel like I was not going to get real science in this book. But I am happy to say that I was very wrong.

Spring Racing 2020: The Fitness that Never Was

“My training was going so well for … (NYC half, Boston, London, Big Sur, or NJ. Fill in the blank) the fitness was there!”. If I had a dollar for everytime I‘ve heard this over the last few weeks, I would have a lot of dollars. This last training cycle was a weird one for EVERYONE because there was no finish line.
