This is the second computrainer workout we’ve posted, to find the other you can click on the computrainer tag above, or in the sidebar tags.
Depending on your desire to ride your bike inside, you can get this workout going when you’ve got that extra jolt of motivation. We like to think that an hour on the computrainer is equivalent to 1.5hrs outside – in some cases probably more, provided you keep it steady. So, if you can put together 2 hours, or even 3 hours on the trainer you’re getting yourself some good mileage. In the winter, for long course racing especially, low HR rules all so throw on that HR monitor again. Know your Aerobic limit.

Here’s a good indoor bike trainer workout for those winter months, or even during the racing season when you just need something different. Getting on to the trainer is the best way to keep your legs going through the year. Even if you can make it outside most of the time, rarely do we make the outdoor ride as productive as an indoor session. Time being equal, indoor will more than likely be more beneficial.
First, get your Heart Rate Monitor on and know your aerobic HR limit. You can get a very good approximation using the Maffetone formula. We put this up in an earlier post but there are many indepth methods for getting your precise number.

This calculation was created by Dr. Phil Maffetone and has been tried and tested by numerous athletes, including Mark Allen. It’s a good calculation and has been shown to quite accurate in most cases for determining your Maximum Aerobic HR: a.k.a. the point below which you should keep much of your Ironman training, and most of your winter training. We started using this limit in the winter months of 06/07 for all of our winter training. This meant walking up hills until our aerobic fitness caught up with the rest of our system. Embarrassing at times for sure. Come race season 2008, more than year later, the differences were unreal. The one downside to this approach is you have to be patient and you have to train a lot. As a minimum, 4 hours per week of running (on top of cycling, swimming etc.)would be a good volume to which you would see some major improvement. Continue reading Maffetone Aerobic HR calculation
