Alternative Resistance Training - How It Compares
With Free Weights
Over
the past ten years, there seems to be a plethora of home gym devices
that promise all the benefits of weight lifting, but instead of
lifting actual weight, you're using what I like to call alternative
resistance.
Alternative resistance can be found in the form of
stretchy (springs and elastic bands that offer resistance when stretched)
and bendy (long composite rods or beams that offer resistance when
bent).
These alternative forms look cool and innovative but
the question remains: Are these methods just as good or any better
than using real weight?
I discovered the answer when I spent three solid years
using nothing but alternative resistance - here's what I learned:
From the standpoint of building pure all out strength
and muscle, it's kind of hard to top real weight.
This is largely due to the fact that alternative resistance
has a pretty sharp resistance curve as the medium is stretched or
bent. So, at the start of each rep you have little to no resistance,
it grows to about half as much resistance at the midpoint and then
is at the most resistance at the full extension of the rep.
While
it's certainly true that the level of resistance on a muscle also
changes during a rep with classic weight, the degree of change is
not quite as drastic. So in the end, real weight has a tendency
to place more stress on the muscles through a wider range of motion
time after time.
I know some might market this resistance curve by
telling you that you get stronger because the resistance grows as
you stretch or bend the device, but that's like focusing on the
glass being half full. The other way to look at it is that the device
also slacks off resistance on the way back down, essentially letting
the muscle relax a lot more. So instead of looking at the glass
half empty or half full, I find it's best to just fill the darn
thing to the brim by using real weight.
Alternative resistance does have its place though.
It's particularly effective for rehab and corrective strengthening
exercises. Since the level of resistance of these techniques is
best when the device is finely tuned, the practitioner can adjust
the tension on a minute level to best meet the client's needs. It
definitely allows for a safer and more controlled level of resistance
where overdoing it by just a few pounds could lead to another injury.
A classic advantage of alternative resistance has
long been portability and versatility. Many fitness buffs use elastic
bands to keep a workout schedule while traveling. At the same time,
these bands allow you to use resistance in nearly any motion you
can imagine which makes them incredibly versatile for functional
training.
These days however, we have suspension trainers that
offer just as much portability and use real weight (body weight)
for resistance and most cable machines can offer just as much versatility
with heavy iron stacks.
In the end, if you are looking for resistance with
classic moves, I highly recommend using real weight. If you're bringing
something back to form, then alternative resistance is probably
your best bet. And as far as portability and alternative moves are
concerned, I would use alternative resistance if it's what you prefer
or as a secondary option.
Don't let the hype fool you though. Just because it's
a new machine or device, don't expect it to carry any more weight
as far as results go, unless you are actually lifting real weight.
