The knee is NOT a hinge. It can twist and slide.
The shin bone / tibia ends rather flat, while the thigh bone / femur meets this flat top with two convex round bony ends. There is no connection or stability inherent in the joint or skeletal structure of the knee. All restrictions to this joint, making it appear to some as a hinge, are the result of soft tissue structures.
Depending on the density and strength of each person's soft tissue the knee joint might present with more or less of this passive support.
Real knee support requires active engagement of muscles. The resulting forces have a strengthening and supportive effect on the knee joint.
However, because of the open structure of the bony parts of the knee joint, movements in all directions are possible. Trying to support the knee only linearly, as if it was a hinge, leaves it vulnerable to strain in all the other directions.
One of the muscles that can provide an aspect of knee stability is the quadriceps, or...
Anyone who has experimented with rolling the sole of the foot knows the results.
The foot feels more loose and forward bends are less restricted.
The reason for this miraculous trick is often assumed to be lengthening of the fascia tissues under the foot. Namely the Plantar Fascia.
However, this piece of fascia is generally so strong, it won’t respond to rolling with lengthening.
Still we feel and can experience rolling the sole of the foot creates length.
What is going on?
More than creating length, we are aiming for mobility.
The ability of the layers of fascia membranes to glide over one another will provide more mobility than lengthening the tissue. At the same time tissue strength and integrity is preserved.
Now that we know we’re looking to restore tissue glide, we can ease off the intensity - you’re not going to squeeze the plantar fascia into a longer shape.

This video features a short explanation of two perspectives on drinking water during yoga practice.
Drinking water during yoga practice is an at times hotly debated topic. Many people suggest a traditional reason why not to drink water, others cite government health guidelines.
Among the many arguments for and against, I'm sharing here thoughts on an exercise and a yoga perspective.
Clearly this is not an exhaustive exploration of the issue, but I hope it assists in honing in on a direction to esquire further.
