That math is far from right. To illustrate this, I will use an example.
Imagine you have two guys, guy A and guy B. Guy A has a bone breadth ratio of , resulting from 16″ shoulders and 10″ hips. A rather small-framed guy who, according to the formula, has elite musclebuilding potential. In comes guy B, with a ratio resulting from 22″ shoulders and 16″ hips; a rather brawny, blocky build. Guy B, according to the formula provided, has elite endurance potential.
From the examples I provided, I could picture guy A as a sprinter, or maybe a point guard, and guy B as a powerlifter or offensive lineman. Doesn’t make sense to calculate musclebuilding potential as shoulders/hips; the larger each measurement is, the larger the frame, and, consequently, the burlier the person. The formula is wrong. This formula is better suited to calculate the aesthetic potential of a bodybuilder, since the more tapered the body, the more aesthetic it is; the strongest and more muscular men, such as powerlifters, shotputters and offensive linemen, have rather large hips and shoulders, putting their ratio closer to 1 than, say, a hurdler or basketball point guard.
Help I have a friend who is a gym goer Im not sure of his quantity or how long he has been taking steroids, but stopped recently because he had really bad neck pain. No dr or scan, ultrasound etc showed anything. Put on huge pain killer amounts didnt help alot but felt after about six weeks some relief. Until today when he thinks a prior knee issue has flared up. If this a result of steroid abuse how long before it heals? Im pretty sure he wont touch them again. He can handle all over aches and pains but these last two injuries have had him off work.
