Beast deadlift! I got a stupid question (not really familiar with bands, just a little physics), does that mean the bar is heavier at the top because it's less stretched? If so, then what is the difference between using the bands regular (attached to the floor) vs reverse band? It seems that both of them makes the bar heavier at the top.
1. Yes.
2. Regular bands produce accommodating resistance, while reverse bands deload. In both instances, the bands have a different "feel", and it's hard to describe until you try both.
There are two important differences in my experience. First, regular bands destablize the weight and take you out of the groove, whereas reverse bands stabilize the weight and put you into it. There's an explanation for this grounded in basic physics, but I don't know it.
Second, regular bands produce what's called overspeed eccentrics--the bands "shoot" you through the eccentric portion of the lift--while reverse bands produce what I might term underspeed eccentrics--they work like a bow being drawn and seem to have a very slight catapult effect (though I haven't seen this written about anywhere, so I'm just guessing). Overspeed eccentrics is important for dynamic-effort training because it develops reversal strength, or the ability to cause a weight to change directions very quickly.
Reverse bands are more likely to be used in maximal effort lift because a.) doing max-effort training with bands can, quite frankly, be unstable and downright dangerous and b.) they allow you to overload the top portion of the lift. The feel of being under 500 lbs. in bar weight is VERY different from being under 500 lbs. in bands.
Thanks. So let's say a band will add 100 lbs when stretched, i'll give this two scenarios:
Band attached to barbell with 500 lbs: @bottom you will be pulling 500 lbs, @top will be 600 lbs.
Reverse band attached to barbell with 600 lbs: @bottom you will be pulling 500 lbs, @top will be 600 lbs.
What's the difference between these two then?
Besides what I previously mentioned, reverse bands will typically deload at a consistent rate. This isn't necessarily always the case, but reverse bands are usually larger bands meant to be hung from the top. Therefore, with reverse bands, each pound might be spaced out at an even interval, so the bands load consistently.
Regular bands, on the other hand, often do not load tension at the same rate. The shorter a band is, the faster it will produce tension, and doubled and quadrupled bands will gain tension at an exponentially greater rate than simple single bands. Therefore, one can fail an attempt with one type of band that produces 100 lbs.' of tension at the top and no tension at the bottom and succeed in another attempt with a different band that produces the same force at the top and bottom if the bands load differently. It's all a matter of how the lifter's strength curve corresponds to the band in question and whether the lifter can produce enough force to overcome the accommodating resistance.
What goes through your head when you approach a bar with 700+ lbs on it?!
The same as what goes through my head when I approach a bar with 135 on it. I suppose it's more fun--that's part of the reason why I do a lot of reverse bands--but the mindset is the same.
I'm really looking forward to reverse band pulling tomorrow now. Assuming I can talk the group into doing it.
Good work KPK.
I need to check your log to see how this went. I LOVE doing these.
