How does the Bowflex Revolution supposedly double the resistance on the leg press excercise to 600 pounds ?

Question

It doesn't feel like 600 pounds to me. And I just can't understand how it doubles it? I mean I looked at it, I tried to figure it out, I searched online. It just doesn't feel like 600 pounds of resistance, nor can I see how it doubles it. Maybe there is some physics that I do not understand.
The only thing I have come up with is that if you do the press with one leg at a time, then you are doing 300 pounds using one leg, which is "like" doing 600 using both legs, so maybe that is what Bowflex means? (I am not saying you can do this exercise with one leg or that it is proper. Do not go do this and say that you did it based on what I said. You could hurt yourself doing the leg press using only one leg, so do not do it without consulting an expert first. I am just asking)
Is there something I can do to make it double the resistance?

This is the new Bowflex, it doesn't use bows, it uses spiraflex resistance plates. they offer real world resistance and linear/even resistance all the way through from the beginning to the end, even without the building momentum that you have with free weights (the throwing effect).

Once again, I do not want someone to try a one-legged press and hurt themselves, so I am absolving myself of that.

When I said it doesn't feel like 600 lbs., what I meant was that it feels like it is still 300 pounds. I don't think it actually doubles is what I mean, and thats too much difference to account for it not being real weight.

Answer 1

nothing wrong with the one legged leg press just as long as the form is correct.

the resistance used by machines almost never transfers into real-world poundages. if you wan't to lift "x" amount of weight then switch to free weights. the Bowflex is not designed for those interested in training for power
