In some cases, an audible snapping or popping noise as the tendon at the hip flexor crease moves from flexion (knee toward waist) to extension (knee down and hip joint straightened). It can be painless. [2] After extended exercise, pain or discomfort may be present caused by inflammation of the iliopsoas bursae. [3]
A back extension is an exercise that works the lower back as well as the mid and upper back, specifically the erector spinae muscles. There are two erector spinae, one on either side of the spine, that run along its length. These are formed of three smaller muscles – spinalis, longissimus, and iliocostalis. [1]
The leg extension is a good exercise for isolating muscular contraction in the quadriceps, [14] but as with all isolation exercises, should be included in a holistic resistance training program working all muscles, especially antagonistic muscle pairs (such as the quadriceps, hamstrings, and gluteal muscles), to avoid muscular imbalances, which ...
Nellie Barnett, CPT, shares three common form mistakes that lead to low back discomfort from the hinge pattern lift, like improper core bracing and hinging. The Truth About Lower Back Pain From ...
The goals of performing these exercises were to reduce pain and provide lower trunk stability by actively developing the "abdominal, gluteus maximus, and hamstring muscles as well as..." passively stretching the hip flexors and lower back (sacrospinalis) muscles. Williams said: "The exercises outlined will accomplish a proper balance between ...

Bridging exercises are done with a flexed knee to lessen the stretch on the hamstring (a knee flexor) and focus the hip extension work on the gluteus maximus. In that same respect, the reduced knee flexion makes plantar flexion work comparable to a seated calf raise, due to the lessened stretch on the gastrocnemius (like the hamstring, also a knee flexor).
Many variations of this exercise are employed throughout the world, most commonly the balancing of the body on the hands and the feet. It is intended to improve lower back and gluteus strength. Examples of bridging in sportive or self-defense applications are seen in Kung Fu, Judo, Brazilian jiu jitsu, Capoeira, mixed martial arts, and wrestling.
