Chair pose is really good for the pelvic floor, which is stretched when going down, and lifted when coming up. Start in mountain pose, with your arms out in front of you, parallel to the floor. Bend your knees and push your hips back in a squat, as if you were going to sit into a chair. Keep your hips higher than your knees.
Weight Lifting and Training
Published in Christopher L. Vaughan, Biomechanics of Sport, 2020
Based on the above research, several summarizing statements are appropriate: There is no objective scientific evidence that the squat exercise to the “thighs parallel” position will damage the knee joint. The possible harmful effects of the full squat on the knee joint are controversial. Any “bouncing” action to help initiate ascent from the full squat position will subject the knee joint to much higher mechanical stress.Squats should be performed with a slow, controlled rate of descent to the “thighs parallel” position followed by an immediate initiation of the ascent if stored elastic energy is to be recovered and aid in the ascent.The torso should remain as close to vertical as possible, relative to the anthropometry and flexibility of the trainee, during the entire lift.The movement of the knees forward during descent should be minimized; maximal forward movement should place the knees no more than slightly in front of the toes.Every effort should be made to maintain stable form (pattern of motion) during every repetition in order to load the muscles in a consistent manner.
Exercise Prescription for Apparently Healthy Individuals and for Special Populations
Published in James M. Rippe, Lifestyle Medicine, 2019
Overload will only result in an adaptation to the muscle groups and physiological systems that are stressed in training. Specificity of training applies to the motor units involved (e.g., muscles used, joint angle), speed of contraction, and the energy systems and primary substrates used (e.g., aerobic versus anaerobic metabolism, fat versus carbohy drate). Unless a person is severely untrained (e.g., frail elderly), strength training will do little to improve cardiorespiratory endurance and vice versa. Furthermore, although distance cycling and running are both aerobic activities using the legs, the carryover from training in one mode to performance improvement in the other is limited. Similarly, while squat training mainly improves quadriceps strength, this improvement may not be recognized when testing with another exercise (e.g., leg extension) that uses different motor unit recruitment and accessory muscles. Therefore, in addition to training specifically toward a person’s goals, assessment of improvement should involve testing that is congruent with the training that has been employed. The more specific a person’s training goals (e.g., athletic performance), the more important these issues become.
The influence of an 8-week therapeutic exercise program on the patient experience of patellofemoral pain: a qualitative descriptive study

One of the main goals of the therapeutic exercise program was to affect patients’ habits and behavior after its conclusion. Patients gave a rich description of how they incorporated the newly gained knowledge into their daily life after the conclusion of the program: Now I remember to use certain muscles even when I walk. It’s always in the back of my head. (F_27)I don’t lock the knee anymore when I stand straight. I used to extend my knees fully and now I try to avoid it and they don’t hurt as much. (F1_16)Yes, I definitely changed my habits. I’m aware of my movements all the time. How to walk correctly, how to squat correctly … If I don’t do something the way it should be done, my knee reminds me of it. Yes, it really influenced my behavior. (F_34)
Training high level balance and stepping responses in atypical progressive supranuclear palsy: a case report

Our patient’s performance on a unilateral squat test helped us understand his ability to hike over boulders commonly found on the trail he took with his dogs. The squat task mimicked the motor control and strength required to lift one’s body weight while stepping onto a boulder or walking up a hill, a skill frequently required during hiking. Similarly, one must lower their body weight while progressing from an elevated surface (e.g. a boulder) to the ground or manage change in trail elevation. At pretest, he was unable to perform the task without hand hold support. This finding suggests not only possible balance impairment, but potentially strength deficits not detected with manual muscle testing. Improvements demonstrated on the unilateral squat likely contributed to his desire and report of being able to hike over rocks.

A deep squat requires high range of motion of the hip and knee joint (Bagwell et al. (2016); Shelburne and Pandy 2002; Smith et al. 2008). Repititive end range hip flexion has been shown to contribute to young adult hip pain in some mechanical hip disorders (Philippon et al. 2007; Lamontagne et al. 2009). Furthermore, it is hypothesized that premature conflicts between femur and acetabulum and high cartilage contact stresses can lead to early osteoarthritis of the hip joint (Mavcic et al. 2002; Ganz et al. 2008). Clearly some variations in hip morphology are pathological however in most cases the morphological abnormality is more discrete and difficult to identify (Reijman et al. 2005; Hosnijeh et al. 2017). The calculation of individual hip joint stresses using discrete or finite element analysis could potentially identify at-risk hip joints (Genda et al. 2001; Mavcic et al. 2002). However this computational simulation technique requires the input of accurate hip joint loading data during challenging hip joint motions such as the deep hip flexion squatting motion.
