You may be surprised to find that the calves affect the hamstrings and vice versa.
What is really interesting is how these two sets of muscles affect each other in straight leg positions. Often times the stretch you feel in a forward bend (or the discomfort) isn't so much the hamstrings but the calves.
The calf stretches article includes both passive calf stretches (like the ones shown above, and active calf stretches. Be prepared for some discomfort!
When you stretch the toes you are generally stretching muscles that cross the ankle and that attach from the toes to the lower leg bones (the tibia and fibula). If you actively stretch these muscles (i.e. activate and strengthen them in a lengthened or shortened position) you practice stabilizing the feet and ankles. You may find that activating your toes while you stretch them can help improve ankle flexibility and control. It may also, have a positive affect on your knees.
Find out about stretching them in toe and ankle stretches.
Yoga for flexibility exercises that stretch the quadriceps all involve "closing" the back of the knee joint.
Easier quadriceps are those where the hip joint is bent forwards (flexed hip stretches) while more challenging quadriceps stretches which could be thought of as Bent knee hip flexor stretches are those where the hip is bent backwards (extended hip stretches).
One of the simplest ways to stretch the quadriceps is to kneel. (From there you can deepen the quadriceps stretch by leaning back.) If you have difficulty kneeling you may find it helpful to work on these ankle stretches. These can also be helpful for if you have difficulty kneeling with toes tucked under.
Hip flexor stretches work on the front of the hip. These may be useful as warm ups or compliments for quadriceps stretches.
Front to back splits is both a hip flexor stretch and a hamstring stretch though with the torso upright the focus is more on stretching the hip flexors (and psoas) of the rear most leg.
For strengthening and stretching the hip flexors (and understanding why they might be tight in the first place and just as importantly, what you can do about it), read Hip flexor stretching and strengthening.
The sartorius is also a hip flexor, but it also bends the knee. Here's how you can stretch the sartorius using warrior 1: Sartorius stretch, warrior 1
The rectus femoris is a hip flexor that works on both the hip and the knee. While sartorius and tensor fascia latae are also hip flexors that work on both the hip and the knee, the rectus femoris is different in that it crosses the front of the knee joint while sartorius and tensor fascia latae cross the inside and outside of the knee joint respectively. As a result, to stretch the rectus femoris you'll have to do hip flexor stretches where the knee is bent as explained in the next section.
Bent knee hip flexor stretches are a special group of hip flexor stretches that work on the rectus femoris and may also work on the tensor fascia latae. Because the rectus femoris crosses the front of the hip and the front of the knee, it can only be stretched when both the knee and the hip are bent backwards.
While some of these stretches can be thought of as quadriceps stretches, I'd say that they'd be better labeled as stretches for the rectus femoris.
One particularly popular bent knee hip flexor stretch is couch stretch. . This couch stretch article covers shows you how to make couch stretch more effective as well as providing alternative hip flexor stretches.

If you want to stretch your hamstrings in order to work towards splits, then these hamstring stretches can help. (You'll have to work on your hip flexors also!)

Standing forward bend

Standing f-bend using arms

Standing f-bend on one leg
Pyramid pose hamstring stretch

hamstring and hip flexor splits
For a set of yoga poses that can be used to stretch the hamstrings, also check out hamstring stretching yoga poses.
And for a simple seated hamstring stretch check out seated hamstring stretch.
For a set of simple (and relatively easy) postures for stretching your hamstrings, check out Simple postures for stretching your hamstrings.
For more on how the hamstrings and glutes work together in different yoga poses you may find the hamstring anatomy article useful.
Yoga for flexibility stretches for lateral glutes and piriformis include pigeon pose variations as well as low lunge variations.
You could consider these stretches as an extension of the side stretches in the previous section.
In general these glute and piriformis stretches include an external rotation of the thigh relative to the pelvis with a forward bend.
One of my favorite glute stretches is pigeon pose glute stretch.
I often use this version of pigeon as a prep for foot behind the head because the leg positions are quite similiar.
Another hip stretch, which is also a shoulder stretch, is armpit pose.
While it may not be possible to stretch the actual Iliotibial band (also called the fascae latae), you can stretch some of the muscles that work on it (fibers of the gluteus maximus, tensor fascae latae and vastus lateralis) with shoelace pose.

Marichyasana E

Happy baby
If you have difficulty hamstring stretching yoga poses, you may find it helpful to stretch the back of the hips by doing bent knee hip extensor stretches first.
Glute stretches like low lunge, modified marichyasana e and Happy Baby Hip Stretch) can be used to increase flexibility at the back of the hip when the knee is bent. This can mean muscles like the adductor magnus long head are affected (since it can extend the hip), as well as some fibers of the gluteus maximus.
These yoga for flexibility poses mainly stretch the inner thighs but also include poses where one or both legs are internally rotated.
Where the previous two sections focused on side bends and stretching the outer hips or abductors, here the focus is on the inner thighs or adductors.
Inner thigh stretches work on the adductors, the muscles that pull the legs inwards. This includes the adductors brevis, longus and magnus, pectineus, gracilis and perhaps also the psoas and iliacus.
Inner thigh hip stretches include Half side split and full side split.
In full side splits you can focus on keeping one leg still and then move the other leg away from this stationary reference point.
The hip crease
A useful reference for stretching the adductors (and for feeling and controlling the hips in general) is the hip crease.
You may find the action of opening the hip crease handy in bound angle pose. But don't forget to counter pose (or counter stretch) by closing the hip crease wide leg forward fold.
Read about both in opening the hip creases, bound angle pose.
Another way you can use the hip crease opening action is in seated straddle splits.
The psoas is a hip flexor (and a lumbar stabilizer). One way to stretch the psoas is with a Reclining Psoas Stretch. Part of what makes this stretch interesting is that it is based on the understanding that the psoas connects to the 12th set of ribs. You can also stretch the psoas with a Standing Psoas Stretch as well as these Standing psoas stretch variations. Other stretches include some Active Psoas Stretches.
One method for stretching the psoas includes learning to add "inner tension" to the lumbar spine. This is covered in psoas stretches. Another technique is to keep the abs engaged, in particular the obliques. This is covered in psoas stretches-1.
Lower back stretches include a variety of standing and seated yoga exercises for increasing the flexibility and control of the lower back muscles and hip muscles. If you have low back pain, check out the low back pain section under the lower back category:
Lower back: Low Back Pain
If have low back pain, you may actually be suffering from weak or imbalanced or ill functioning hip or leg muscles. So if you have chronic low back pain, look at exercises to strengthen and stabilize your hips. Some of those are listed in the section linked to above.
You may find some of the shoulder stretches (below) also helpful for tight upper backs.
When you stretch your back you are actually stretching a part of your spine. Here's a comprehensive list of spinal movements that you can use as spine stretches.
The spine is meant to be flexible. But it's also meant to be strong. You can stretch your spine by taking its parts through simple movement ranges as shown in these spine stretches.
A simple tip for these spine stretches and all other stretches:
Move slowly and smoothly.
If you do that, you'll be focusing on what you are doing. You'll also be less likely to hurt yourself. And you'll be more likely to find optimal movement that then allows you to improve your flexibility.
Side stretches are perhaps one of the most overlooked stretches. These simple stretches can offer a lot of back for the buck if for no other reason than we tend to neglect side bending actions.
Note that the section on side stretches has a lot of overlap with lower back stretches, below. That's because side stretches stretch the lower back, as well as the side of the ribcage. If the hips are included in a side stretch like standing side bend, then side stretches can also be used to stretch the inner and outer hip and thigh muscles.
When side bending the torso, you can make your side stretches active in two ways. You can work at actively lengthening the long side of the stretch. You can also work at actively shortening the short side of the stretch.
As an example, Bending to the right you can focus on lengthening the right side of the torso or on shortening the left side of the torso. You could also work at doing both actions at the same time.
A focus on either lengthening or shortening (or both) causes muscles to activate. These muscles in turn help to generate sensation, both muscle activation sensation and connective tissue tension. Both of these types of sensation allow you to feel your body. They also help to keep your joints safe by keeping them lubricated. You may find that although it can be hard work, focusing on either of these actions can make whichever stretch you are doing feel more comfortable.
If you choose to relax while stretching, do make sure that you create stability. So for example if you want a relaxed spine while bending to the side, and you are standing, the stabilize your feet, or your knees or your hips, or your entire leg so that the muscles you are stretching have a firm or fixed foundation from which to lengthen away from.
One way to improve shoulder flexibility is to focus on your shoulder blades. For tips on how to use and control your shoulder blades read Shoulder flexibility stretches.
If you've got tight shoulders these shoulder stretches and arm stretches can help.
The muscle assisted shoulder stretches are if you want to work while stretching. The gravity assisted arm stretches are for a more relaxed stretching experience. Both types can be used to help improve shoulder flexibility
Yoga shoulder stretches includes traditional yoga shoulder stretching positions like reverse prayer, eagle pose and the shoulder stretch used in prasarita padottanasana C. Hip and Shoulder Stretches are poses which stretch the hips and shoulders at the same time.
Meridian stretches are stretches which are designed to stretch the meridians. The meridians run up and down the sides of the body, arms and legs and correspond to organs.
Because these stretches can be a good way to relax or re-energize, they've been grouped under the yoga for stress category (de-stressing).
The meridians lie within connective tissue and to stretch them the main stretching technique to use is relaxed gravity assisted stretching.
For a particularly refreshing stretching session you can use the meridians to guide the sequence in which you do your stretches. To do that, follow the "flow of the meridians".
