The hamstrings are a set of 3 muscles on the back of our thigh that is often lumped together into one group.  However, individually they are set up to contribute to our movement in very different- and sometimes opposing ways.

The biceps femoris is a major muscle in the Deep Longitudinal Subsystem. It runs from our pelvis to our lower leg and is important for bending our knee and extending our hip. This muscle also helps keep our knee stable and helps control our pelvis when we walk or run.

The most common dysfunctional pattern of the biceps femoris is to be overactive and tight.  This is in direct contrast to the other two muscles of the hamstring group- the semitendinosus and semimembranosus.  These muscles are set up to contribute to the work of our Deep Front line as well as lower leg function...and they tend to be weak. 

You know the person- maybe it was you. Your thumb touches your forearm, you can dislocate your shoulder at will, your skin is really, really stretchy. Remember when you put your feet behind your head and walked on your hands? Everyone loves that trick.

Hypermobilty Spectrum Disorder and Ehlers Danlos Syndrome go beyond your joints. The spectrum represents a myriad of symptoms linked to disrupted collagen production.

If you have extreme flexibility and a litany of internal medical issues, perhaps its time to learn more about the spectrum.

Always, ALWAYS, consult with a medical professional. Never self-diagnose…But always be your own best advocate. Read on…
