Below are stretches for many muscles that are often tonic, or tight.
Adductor (Groin or Inner Thigh Muscle) Stretch
Do this second one too! Your hamstrings cross two joints and have two main actions – extension of the hip and flexion of the knee. The stretch above stretches your hamstring at the hip and knee, the one below focuses more on the hip.
Hip Flexor Stretch
Low Back Stretch
You should feel this along the side of your body.
Erector Spinae – Cat/Cow Stretch
The photo shows the cat version, arch your back to include the cow position.
Peroneal (outside of calf) Stretch
The cat/cow stretch works for this, but a better way to gain thoracic mobility involves using a foam roller, if you have one. Gently roll your upper spine up and down the foam roller as shown below.
