Shoulder internal rotation is one of the most commonly restricted ranges of motion in both overhead athletes and office workers, for completely different reasons that produce the same mechanical consequence: the humeral head cannot sit centrally in the glenoid during overhead movements, the supraspinatus tendon gets compressed, and pain or injury follows. In overhead athletes…
Battle ropes sit in most gyms but get used by a minority of members. The exercise looks unusual — swinging heavy ropes in wave patterns doesn’t resemble any conventional cardiovascular or strength exercise — and its place in a training programme is less obvious than a treadmill interval or a barbell lift. The research tells…
The straight barbell curl is the classic bicep exercise. Most programmes include it, most beginners start with it, and most experienced trainees return to it as their primary loaded curl movement. It also produces wrist and forearm discomfort in a significant proportion of trainees, particularly those who have had wrist injuries, naturally have limited forearm…
The rectus femoris is the quadriceps muscle that crosses two joints rather than one. While the vastus lateralis, vastus medialis, and vastus intermedius cross only the knee, the rectus femoris originates at the anterior inferior iliac spine of the pelvis and crosses both the hip and the knee. This two-joint architecture means the rectus femoris…
Altitude training is the gold standard endurance performance intervention for decades. The reduced oxygen partial pressure at altitude stimulates erythropoietin release, increases red blood cell mass and haemoglobin, and produces measurable improvements in VO2max and endurance performance when the athlete returns to sea level. It is also expensive, logistically complex, and inaccessible to most athletes…
