Endurance power moving, such as loading trucks or pushing vehicles; can only be done for so long before you give yourself a heart attack or run out of steam. Short breaks of qigong, or martial meditation will reset blood pressure, allow all internal organs to catch up, and prevent cramps; while still keeping your self pumped up.
Most view moving as a gymnasium setting as a weight with so many repetitions, this is child’s play. Professional longshoremen, warehousemen and physicists all use a different terminology, foot-pounds per day. This is measured in tons per day, such as the song, Sixteen Tons, about loading coal.
I worked on the waterfront loading and unloading 180 pound sacks of coffee. Most weight lifters cannot last the thousands of repetitions of moving, and the few that do will not show up for work after the third day. Only about one in five obviously strong and fit men, who claim they can do the job; will last the week. Most marathon runners have the endurance, but are all legs, and have no power.
Rowers, commercial fisherman, mountain climbers and lumberjacks do the best: these all entail fluid movement.
Internal energy work insures that all of you internal organs are working together at maximum, so you can accomplish moving pyramids.
Being in good shape from Qigong, Tai Chi, Hsing-I and Internal Northern Shaolin; makes it easier to get back in shape for other physical movement, since it is the most efficient way to move. It also allows one to learn a new discipline quicker.
