2. Functional exercise is always a means to an end (with examples of gathering wood to stay warm, lifting stones, and doing calisthenics in
army to stay "strong enough" to fulfill duties). In other words, perform movement patterns that are essential to your work or sports environment. I work at a computer for
most part, and so perhaps I should perform some keyboard typing overload exercises. Sarcasm aside, most of us have enough strength to complete daily activities, and to mimic those activities with resistance often does us worse than good. An example in sports would be sprinting with heavy weights attached to
body with
notion that our sprinting will improve, although sprinting mechanics obviously would alter under such circumstances. Moreover, consider elbow flexion that occurs when we lift an object, and
elbow flexion that occurs during dumbbell or machine arm curls. Would
latter not have a positive bearing on
former? Certainly it would, but since it is not "exact" to everyday movements,
author condemns such actions, and without realizing that any "functional exercise" also is not exact to daily activities (unless
same resistance and movement patterns exist, and if so, it no longer would be exercise but activities of daily living).
The author talks around
issue of isolation training to improve function by stating
following: "Training muscles with isolation methods to achieve increased mass in specific muscle is only functional if your goal is to compete in bodybuilding competitions, or specific rehabilitation procedures or as part of a well-designed isolation-to-integration program." Certainly "isolation to integration" could mean performing daily tasks and activities better as a result of larger and stronger muscles that were produced as a result of using machines or free-weights, as has been done for several decades.
He continues: "There must be a goal motivating
selection of exercises or one cannot ascertain whether
outcome is functional or dysfunctional." In
previous paragraph he clearly acknowledges that a weak chain can be made stronger by (greater) isolation, yet ignores its value unless it can be proven that
outcome improves function (in
individual’s best interests to achieve another goal). If that goal is to feel better, look better, and function better, then any exercise in any medium (free weight, machine, rubber band, calisthenics, etc.) has that potential. The extent to which that happens varies, thus depending on
quality of movement and effort far more than how dynamic (the use of several muscles in an unfixed environment) or unstable an exercise happens to be.
Moreover, a few things are wrong with
author’s statement above. One,
ultimate goal may be aesthetics, and there is nothing wrong with that, but pointless according to
author since that aspect of a fitness program means nothing to him. Two, injuries are
result of weak links, and there is no better way of addressing this issue than through means of specific exercise that is as isolated as possible, whether through single-joint movements or not. It is like working on an entire house when you know
problem to be
support beams. If you need to strengthen
support beams, then forget about
shingles or windows. Three, function required in specific activity requires practice of
specific activity to improve that ability, whereas exercise provides general conditioning and strength improvements that then support
specific sporting movements. Hence, truly functional training involves
specific motor skills of a particular activity, and not movement patterns that "sort of" resemble an activity but which uses different loads, different velocities, different movement patterns, different balancing requirements, etc.
3. Selection of an exercise or exercise regimen must consider
desired outcome on all primary physiological systems of
body (including hormonal, musculoskeletal, circulatory, immune, thermoregulatory, visceral and neurological). And "every intent and attempt should be to improve
exerciser’s physiology through exercise, or
exercise regimen can’t be considered functional." Please explain how stabilizing on a Swiss ball while performing dumbbell presses can account for all
primary physiological systems, whereas working
muscles with heavier resistance and with greater physical/mental effort in a stable environment cannot.
Moreover, it takes little effort to improve all these systems even on
worst program (whether stable or unstable), and so it goes without saying that improvement will occur in all aspects to some extent. To what extent improvement will occur depends on many factors more important than trying to maintain balance while moving weights in
hopes that you will not fall off a ball or wobble board as opposed to using a machine, factors such as
quality and effort of
program overall. Differences in results become obvious if one were to compare a person who (purposely) puts forth little effort while following
author’s "functional" workout with rubber cables and Swiss balls as opposed to a person who tries very hard with an Author Jones intense workout on Nautilus or MedX machines. In this example it should be obvious who will make
best changes, and
opposite also would be true of a person who tries very hard on any so-called "functional" program as opposed to a person whose performance is lackluster while using exercise machines.
4. Selection of an exercise or exercise regimen must take into account a person’s emotional, mental and spiritual components. This statement is obvious, in that a properly prescribed program takes into account
individual, but
author suggests that "the expenditure of
life-force energy on a leg press is not bringing exercisers closer to complete well-being!" (exclamation his). Why should this be
case with
leg press, or why should it not be
case? There is no explanation behind his statement, but he does disclose
following: "when an exercise program is functional, it supports
collective needs of
living organism and
body becomes progressively healthier, which positively influences
emotions and
mind and affording
spirit greater freedom of expression." What a load! (exclamation mine). How is it that a person can become one with
Universe by balancing on a ball or wobble board, or by moving about while yanking on some rubber bands or cable system, yet this cannot be achieved on a leg press? What is
scientific evidence?
