One direction or Bi direction

[gs300tx]

Hey guys, after reviewing the awesome VRT dvd it is my understanding that VRT is one directional and DVR is bi directional tension.

Now, usually if I do one directional tension, I can do more reps, in the 12-15 range per set(at a fast pace like shown in the dvd)
However if I do bi directional the reps become much slower and I can only do 3-5 reps and become winded pretty quick

Is there any benefit to using one type of method over the other?

Thanks

gs300tx,

I developed this on my own without a background of any system of the old-time bodybuilders, so all of my development is by "instinct," or just my personal tapping of the unconscious mind.

What I found to be the greatest "pumping" technique was a one-directional method. Yes, bi-directional will end quicker because it takes less time and exhaustion increases quite rapidly, but the mimicry of the "pump" [vasocongestion], that one discovers in a heavy weightlifting routine, I found to be most evident in one direction. Then superset with the opposing muscle group in one direction also.

However, when I came upon this forum, many commented they liked the bidirectional DVR method. So it appears to be a matter of your own personal choice from here on in, gs300tx.

Best,

Greg Mangan

Hi gs300tx,
VRT works muscles in pairs.When you perform the exercises bi directional the smaller muscle always fatigues first leaving the bigger unexercised.So in my opinion one directional is by far superior.

I'm in agreement with Greg and Douglis on this, Greg's subconcious insight picked the right course. I've experiented and the pump comes doing it the VRT Way.

Hi Men,

In IPR Trump Von Diligen is quoted on "forced" relaxation. In other words, once the muscle is tensed to the maximum, you relax it to facilitate blood flow. This single-drectional approach works well for DSR's as well. Royce calls this "isokinetic" resistance, which in a very basic sense means there is resistance only in one direction and at a constant speed. In M-7 and PYTP John took the approach of McSweeny that the tension should move both ways, but I believe he has changed his views on that thanks to the experiences and insights of Greg Mangan, Royce and others.

This is a very informative thread! I have ALWAYS done DVR's in BOTH directions...

OK, I'll try to do them in TWO sets- One positive, and then another negative set.

What cadence would be appropriate? Fast, slow, medium?

Thanks guys!

Hi Jaymo,
My suggestion is to do those two sets in different days.

I found that a slow cadence forces the antagonist muscle to do slow negative contractions.This increases the recovery time(of the antagonist) very much.That's why I prefer fast to medium cadences.
