If, like me, you enjoy lacing up your trail running shoes or hiking boots and hitting the trails regularly, you may find that your hamstrings are a little tight these days, especially if you’re not great at stretching regularly.

Running and hiking put a strain on your hamstrings (the generic term for the three muscles that run down the back of your thigh from your sit bones to the back of your knee), which isn’t a bad thing. Adding weight to your muscles helps make them stronger, and strong leg muscles contribute to balance and your ability to perform everyday tasks like standing. Until they don’t.

Overloading the hamstrings, whose function is to bend the knee, does not shorten the muscles, it just makes them feel that way. On the other hand, it can inhibit the ability of the hamstrings to move through their full range of motion. By nature, hiking and running move the knees and hips through a fairly short range of motion, and when you do these movements repeatedly, you can feel quite stiff when you go to put your shoes on in the morning.

Why does it matter if I have tight hamstrings?
