Doing the Right Thing(s)
The glutes, hamstrings, lower back, are all contracted maximally when the thigh bone (femur) moves backwards out of line with the torso, and if the head moves down simultaneously, the abdominal muscles are contracted maximally as well — disputing the notion that muscles work antagonistically — than as is more often the case, complementarily, or synergistically.
The obvious case in point is the contraction of the biceps of the arm. That contraction of the biceps does not produce a relaxation of the triceps — but requires the triceps to be maximally contracted as well. And so It is the case that when the back muscles are maximally contracted, the abdominal (front torso) must be maximally contracted simultaneously — or the maximum contraction in one direction with the complete relaxation of the stabilizing muscles in the other direction, would pose great risk to the spinal column — which has structural strength and integrity by equalizing the pressures to these vulnerabilities in all directions.
That is to note that if one anticipates absorbing a blow to the midsection, one would not simply contract the front abdominal muscles, but all the muscles surrounding the midsection simultaneously for maximum structural strength — which then gets dissipated through all the other muscles of the body. That is one of the greatest reasons for older people to maintain maximum muscularity throughout life — not because they can hit another harder, but they can absorb the blows from any other effectively and efficiently so as to render themselves impervious to those injuries — including the inevitable and dreaded falls — which are more likely than finding themselves in a fist fight.
Muscular people bounce right up — or lie there briefly thinking if everything is still responsive and in working order — and slowly are on their way again. Muscles are not only decorative but highly functional — for many different reasons this way. So while many will think what is the point of developing the gluteus muscle — the fact that it is the largest muscle of the body and likely to remain so the older one gets, probably serves an evolutionary survival purpose — in padding and protecting the well-recognized fragility of the hip structures that have served as a reliable indicator of survival in elderly populations.
In younger people in their most prolific years, the dancers, gymnasts, ice skaters, are probably most notable for their outstanding ranges of motion — by which they awe the competition and judges with their ability to easily move their legs back and even grab their foot above their heads. But most people are not built that way — so moving the leg back even slightly out of line with the torso is likely to produce a maximal muscle contraction and development — and can even be done lying down on one’s side in comfort. In this respect, lying on one’s back or stomach is more problematical because of the pressures against the breathing muscles of the lower torso — when a heavy weight is employed in the traditional machines designed for that purpose.
However, as I’ve frequently pointed out before, maximum muscular contraction is more a function of the range of movement — than weight used in a limited (unchanging) range of movement — with the weight often acting as an impediment to the expression (articulation) of the muscular states from fullest relaxation to fullest contraction. That is primarily a function of knowing in which position the muscle is relaxed and contracted — and not of the resistance and effort of moving from one to the other. It’s like a light switch: it doesn’t matter how much resistance or effort is required to get from the “off” position to the “on” position. What matters is whether it is fully on or fully off — often being the exact same motion. That is the “digital” world of reality.
That is the pumping effect we are trying to achieve — in developing any muscle. If the muscle is not articulating the fullest flow (circulation), then no amount of doing that movement with any amount of weight and resistance will produce the desired effects. No matter how much weight one stands up straight with in the squat or deadlift, the gluteus muscle will remain relaxed — because it requires the fenur to be moving back out of line with the torso to contract, and contract strongly. That is directing the flow to and from any muscle — producing the desired function, form and development (health).
If one does the wrong movement that doesn’t achieve those changes of muscular states, it doesn’t matter how much weight and resistance one uses — though admittedly, one is using more weight and resistance. But if one simply wants the results — without the impediments to it — which is the underlying question of every inquiry, then one has to examine what movement produces those changes — regardless of weight, resistance, repetitions and all the other irrelevant considerations — because time is running out on everybody — and that is why we are exercising as a lifelong practice.
