Have you maxed out your 210 lbs of resistance on your Bowflex? The Bowflex 310 power rod upgrade upgrades your Bowflex from 210 lbs of resistance to 310 lbs by adding two 50lb rods that screw into your rod box. Compatible with the Bowflex PR3000, Extreme SE, Ultimate, Extreme 2 SE, and Ultimate 2.
Maxed Out No More
*The 310lb upgrade and 410lb upgrade both consist of two 50lb power-rods. The difference between the 310 and 410 upgrades is simply where the two power-rods attach to the power rod box. The 410 slides onto the back of the box while the 310 inserts into the two open holes in the power-rod box. If your power rod box on your homegym does not have open holes or a spot on the back to slide an upgade in to - your model is not upgradable.
