One thing that you may have noticed with your Bowflex fitness machine, is that it only has 210 pounds of resistance. That is unless it is one of the machines that features SpiraFlex technology that doesn't use power rods. For most women this may be enough resistance but for men in general, it just isn't enough.
A Must Have Item for Leg Workouts

This particularly holds true if you have the leg extension bar and are doing leg exercises. Fortunately Bowflex sells extra power rods that you can add on to your machine and boost the total resistance up to a total of 410 pounds, which is plenty of weight for building leg muscles.
Two Sets of Power Rods for Maximum Resistance

However; in order to get to 410 pounds of resistance, you must first go to 310 pounds with the addition of one set of extra power rods. The addition of a second set will then take you up to 410 pounds of total resistance.
Installation Only Takes a Couple of Minutes

So how difficult is it to add on the extra power rods? In fact it is quite simple and will only take a couple of minutes at the most. Also, if you have a machine that features SpiraFlex technology, adding weight is even easier because you simply plug the extra discs right on in only seconds.
Buy Them With Your Machine and Make Monthly Payments

A set of extra power rods can be purchased for only $99. This will only add a few extra dollars at the most to your monthly payment if you are financing your fitness machine through the Bowflex finance plan. So you may want to consider picking up an extra set or two of the power rods right from the start and save yourself the hassle and the wait.
