Why do tight hips cause lower back pain?

According to Squat University, tight hips force the lower back to compensate for movement the hip can't perform. In one patient case, a stiff right hip couldn't extend during a bird dog exercise, so her lower back moved instead, which directly triggered her back pain. Fixing the hip restriction removed the compensation and the pain.

Why does a rotator cuff injury still hurt after doing shoulder external rotation exercises?

According to Dr. Aaron Horschig, basic external rotation exercises strengthen the rotator cuff but don't train the shoulder in the overhead position where lifters like Sammy actually feel pain. The snatch demands stability with the arm overhead, so rehab has to be done in that specific position, not just in a neutral, arms-down posture.

Why does my hip pop when I lower weight during a hip flexor exercise?

According to Dr. Aaron Horschig, the most common cause is the iliopsoas hip flexor tendon snapping over a bony prominence in the pelvis as the hip moves. This mechanical snap can happen with or without pain, and it was the exact issue one of his patients experienced every time he lowered the weight during a hip flexor exercise.

Why does the shoulder hurt when bench pressing?

According to Squat University, shoulder pain during bench press is often caused by a weak posterior rotator cuff that fails to stabilize the shoulder joint. When you try to produce force off this unstable foundation, the shoulder compensates poorly, leading to pain — as seen in a patient who couldn't bench pain-free for 2 years.

What is the Bill Kazmaier fulcrum technique for back exercises?

According to Squat University, it's a technique picked up by Dr. Stuart McGill from strongman Bill Kazmaier that uses boards to create a fulcrum during a grip-and-contract movement. Raising the fulcrum shifts neural drive to the upper neuromuscular compartments of the erectors, while lowering it shifts drive to the lower compartments, letting you target the spine segment you need.

What is the best exercise to strengthen the lower trap?

According to Squat University, clasping your hands behind your head and lifting your elbows overhead is one of the best ways to strengthen the lower trap. Hold the position for 5 seconds and perform 10 to 20 reps. This aligns the arm at an angle overhead, which research cited by the creator shows effectively targets this mid-back muscle.

What exercises help rebuild the hamstring after a strain or tear?

According to Squat University, four exercises help rebuild the hamstring after a strain or tear: the hamstring bridge, the single leg bridge with a slider, the single leg RDL, and the Nordic curl. Together they progress from isometric holds to eccentric loading and hip- and knee-dominant patterns to fully rebuild strength.

Why does a strong weightlifter's back still hurt?

According to Squat University, strength doesn't prevent pain if the spine is loaded in a vulnerable position. Carson, an incredibly strong lifter, had no pain with a neutral spine under load, but pain appeared immediately once he rounded his lower back during the same tests — showing the issue was positional tolerance, not overall back strength.
