The core synergists workout is excellent. the abdominal workout is intense. Both core and abs are very important to my riding. the stretching and aerobic routines are wonderful in helping me lose weight. also, the chest, shoulers, back and arm workouts help in developing muscles for good posture, making riding in the drops better, and all of the workouts of course help in weight loss and muscle development.

No only are there workouts that build your calves and glutes, but the tendons that connect these muscles, as well as the IT band are worked.

I have found it very beneficial for me. Some of the much better atheletes on here may not benefit at all, like rpeterson above I assume. I don't follow the nutritional plan exactly, since my vegitarian, organic diet is almost exactly what they have recommended. I didn't purchase their protien shakes, I got muscle milk at costco, and I still use cytomax on my rides.

I has helped keep the winter weight off, while keeping my entire body in shape. cycling is a muscle memory, repetitive sport. P90X is a muscle confusion series of workouts, so you don't get used to doing the same thing. overall it has made me stronger.

Perhaps it's not for you. It can't be for everyone, and I'm sure it's not. The intent of my thread was to see who is doing it, and speak to them about it, as well as answering questions about it for others, which is what I'm trying to do now, as it has helped me tremendously.
