The Science-Based Method to Loosen Tight Hamstrings

Muscle tightness is common and generally not a cause for concern. In most cases, the symptoms will go away on their own after a couple of days. Most hamstring injuries respond well to nonsurgical treatments, and stretching can help with pain relief.
Tight hamstrings can make it difficult to walk or stand comfortably, which might affect daily functioning.The hamstrings are a group of muscles that run down the back of the leg. There are three hamstring muscles:
biceps femoris
semitendinosus
semimembranosus
They support bodily movementsTrusted Source, including walking, running, and jumping. Tight hamstrings can affect all of these movements and limit mobility. They can feel stiff and less flexible. In some cases, tight hamstrings might occur with other symptoms, such as
cramping
pain
swelling
bruising
tenderness
redness
The hamstrings are more likely to feel tight after resting — for example, the morning after exercising. Having tight hamstrings can also increase the risk of injury.A common cause of tight hamstrings is exercise or another form of intense activity.
Exercises that put substantial strain on the hamstrings can lead to tightness. For example, performing hamstring curl exercises or playing sports such as soccer will target the hamstring muscles.
The tightness will usually occur after starting a new exercise routine or suddenly increasing workout intensity. Some people experience tight hamstrings after long periods of sitting or inactivity. For example, sitting at a desk for several hours might lead to tightness.
In other cases, the tightness might be due to injury, possibly a recurring injury that makes the hamstrings more vulnerable to tightness. The tightness could also be a sign of a sprain or strainTrusted Source
