The majority of the work is
forward flexion (think of looking into your abdominals).
As a society we've come a long way from ancient yoga teachings in where sitting 12 hours / day (often in
forward flexion, forward head) wasn't a norm.
The forward flexion position alone is controversial, which is where the concern can lie.
Forward flexion (rounding) can reach a breaking point and this has been shown through research, excessive
forward flexion is one exact mechanism of causing disc and spinal issues.

forward flexion.
If you don't have time for
forward flexion, leave it out.
It is one of the best exercises you can do as a counter stretch for the many
forward flexion exercises in Pilates mat work.
Avoid
forward flexion of your neck, particularly during work - outs with weights, as this movement can reverse the proper forward curve in the neck, and therefore interfere with your adjustment (which aims to restore and maintain proper alignment).
A little
forward flexion is fine but this is one move we don't need as much as we need the others.
These forward flexion exercises cause risk of impending disk damage.
Spine - sparing techniques: hip hinge, rise from the floor, core strength, avoid rotation of rapid or repetitive
forward flexion with load
We have a limited amount of
forward flexion and we don't feel the damage when we're doing it.
Crunches, sit ups, and forceful
forward flexion against resistance with an abdominal machine accelerate the risk of disk problems.
Physically, this series focuses on spinal extensions (backbends), which alleviate the tension from excessive
forward flexion (forward bending).
Not exact matches
Whenever someone tries to jump or sprint they coil down / load these joints (triple
flexion), and then they forcibly extend these joints to create
forward propulsion (triple extension).
Proper head positioning can help you prevent injury and generate more force, but looking at the ceiling during heavy squats squeezes the spinal discs in your neck, hyperextends the neck, forces the hips
forward prematurely, increases knee
flexion and can easily result with neck pain and injury.
As a whole (all heads working together), the pectoralis major assists adduction (lowering upper arm from side raise position to the midline of the body), medial rotation (rotating upper arm
forward or inward to the midline of the body) and horizontal
flexion (moving the upper arm from a side raise position to the front of the body).
The calves and the bottoms of the feet are going to send the knee
forward and pass it off to the hip flexors, which are going to finish the job of the
flexion of the hip and the bending of the knee.
The hip can move
forwards (
flexion), backwards (extension), out to the side (abduction), and in towards the middle (adduction).
They are
forwards (
flexion), backwards (extension), out to the side (abduction), and inwards (adduction).
Flexion: Bend your body
forward at the joints, such as at the waist for sit - ups or at the knees for high - step exercises.
Its actions are to compress the abdominal contents to stabilize the spine, flex the spine (pull it
forward like in crunches), rotate the trunk to the opposite side (contralateral rotation), and bend the spine to the side (lateral
flexion).
The rest of your body is to remain as still as can be with the naval still fixed
forward while minimizing any spinal
flexion to relieve the hip of its duties.
The hip muscles act on three mutually perpendicular main axes, all of which pass through the center of the femoral head, resulting in three degrees of freedom and three pair of principal directions:
Flexion and extension around a transverse axis (left - right); lateral rotation and medial rotation around a longitudinal axis (along the thigh); and abduction and adduction around a sagittal axis (
forward - backward); [29] and a combination of these movements (i.e. circumduction, a compound movement in which the leg describes the surface of an irregular cone).
Peak knee
flexion angles are less acute when using cues to prevent
forward knee movement over the toes or as a result of fatigue.
When the upper portion works by itself it can assist with bringing the shoulder straight
forwards (shoulder
flexion).
If you are training a lot of
forward spinal
flexion you should also include back extension as part of your movement practice.
Your back muscles pull your spine backwards (into extension), and your stomach muscles pull your spine
forwards (into
flexion).
One problem is that stretching to lengthen tendons will also increased plantar
flexion and knee extension, which hurt running economy — so it may be a case of one step
forward, two steps back.
You want to avoid
flexion movements that compress the neck and spine such as rounding your spine
forward, twisting to the left or right, and bending
forward to touch your toes.
By doing that toe lift, I'm starting to increase the
flexion in the hips with the raising up of the foot and it leads to good mechanics where the foot is coming up and knees going
forward.
Maintain light
flexion in the knees, hips are back to create vertical shins, and shoulders are
forward of the bar
so then, whenever you bend
forward and create
flexion in the spine, you're risking disc injury or only when the hamstrings are tight?
You wrote - «If your hamstrings are tight you are risking disk compression any time you bend
forward...» so if the hamstrings are not tight, there still will be
flexion in the spine when you bend
forward..
When I observe people coming to class with tightness in shoulder
flexion, they will often bring their head
forward.
Restrictions in the superficial front line are seen with
forward head posture, anterior pelvic shift and tilt, knee hyperextension, breathing restrictions in the anterior ribs, and ankle plantar
flexion limitation (11).
In addition, anterior delt will also pull the shoulder
forwards (
flexion), turn the shoulder inwards (internal rotation), and pull the shoulder across the chest (horizontal adduction).
The transverse muscle compresses the abdomen and bends the trunk
forward in
flexion.
Then the head bounces
forward into
flexion.
