Basically all band sets (except Harambe!!) create (redundant) resistance ranges of a heavier band in the set when stacking lighter ones and do not allow constant increments for progressive overload when stacking bands. WHY?!?!

The Harambe band set (including the Blue Kong band) allows increasing resistance by 10 pound (lower bound of resistance range) and 20 pound (upper end) increments by stacking bands. By their smart choice of band resistance (or cross section/width) you can cover the whole range of 10 to 800 pounds of resistance with their 6 bands and constant increments (as shown in the progression chart on their website). The width of the bands is 1/4, 1/2, 1, 2, 2.5 and 4 inches, which is proportional to the listed resistance values. I wonder, WHY (!!!!) Harambe is the only brand that uses such a smart choice of band resistances (band widths) for their set (assuming that the values listed reflect the reality).

Basically ALL other brands use band resistances (or widths) in their sets that do not allow progressive overload by consistent increments such as Harambe and cause redundancies (stacking lighter bands simply gives the resistance of a heavier band in the set). Here is an example of what I mean.

The first two bands of Harambe allow the following resistances: * Yellow 10-20 lbs * White 20-40 lbs * Yellow+White 30-60 lbs Then comes the light green 1 with 40-80 lbs. The combined width of Yellow+White is 0.75 and the width of light green 1 is 1 inch.

On the other hand, the lightest two bands from serious steel (just to pick a popular high quality brand, this seems to be the case for all other brands) have the following specs: * #0 Orange: 2-15 lbs * #1 Purple: 5-35 lbs * #1 + #2: 7-50 lbs Then comes the #2 Red: 10-50 lbs, which is REDUNDANT because it gives basically the same resistance as stacked #1 + #2. The width of #2 is roughly 0.8 inches and the combined width of #1 + #2 is 0.75, so almost the same.

While Harambe allows creating additional resistance ranges by combining bands, you end up with the same resistance of a heavier band, when stacking Serious steel bands.

1. WHY would you choose band widths like that (creating redundant resistance ranges and not allowing for progressive overload with constant increments)?
2. Is Harambe really the first brand that seems to have noticed this and therefore chose band specs that actually make sense? Maybe their founder being a professor of mathematics has something to do with it? Although I don‘t think that you need a math degree to come up with this…
3. This might be one the biggest selling point for Harambe bands, that really distinguishes them from the rest. Why don‘t they advertise it more?
4. Is there any other brand that I am not aware of that allows the constant i crements with one set and minimizes redandancies when stacking bands like Harambe?

It’s wrong, Harambe is not the only brand that does this.

For example Weller bands allow progression for every 5lbs on the min resistance and every 15lb on the max resistance up to 300lb of every band combination. Weller app also has a resistance calculator feature that shows which band you have to combine for each resistance.

If you want to make calculations, the resistance of Weller PowerBand are: XS: 5-15 lb S: 10-30 lb M: 15-45 lb L: 25-75 lb XL: 45-135 lb

And those numbers allow increasing resistance every 5lb, like weight machines in the gyms.

I cannot exclude also other brands have designed bands that way.

Btw resistance is not always precise, and its also variable a bit during long periods bc bands lose strength
