I’ve got lots of stats on my blog, and one of the posts with the most number of hits is my page on the Modified Conconi Test that I did. Interestingly, there’s still little good information on this, and I still think Ross’s Maximum Performance for Cyclists is still the best book out there for explaining this process. The tricky thing is finding the deflection point after reviewing the data.
Here’s my HR data. Note that the first deflection point is supposed to be the aerobic threshold and the second is the lactate threshold. Ignore the 4th point, I was messing with the bike which reduced my watts and heart rate.
Then the cadence data; the first bend in the graph can help you identify the aerobic threshold if the above heart rate graph doesn’t help. Around point 10, I started messing with the shifting to maintain my power, thus the changes in cadence.
And finally the critical power data; when the curve starts to change slope, that’s another pinpoint for lactate threshold. This is the graph I’m hanging my hat on for my heart rate zones.
Deflection points in these graphs indicate both the lactate threshold rate and the aerobic threshold rate. However, finding those points is the tricky part.
Here are the heart rate zones I ended up selecting, which are far different (within the zones at least) than my original HR data.
Interestingly, my maximum heart rate hasn’t changed much. It’s zones 2 – 4 that have really been tweaked, and I can definitely tell. Training in the initial zones was been brutal for me. Enough that I readjusted to the final zones (by interpreting the deflection points differently and paying more attention to the critical power graph). The final zones do feel right…when riding in my prevous HR zones (higher than the 2007 numbers, by the way), it seemed like I was always in zone 4 and easily spiked to zone 5. Now when I’m training, I’m generally in zone 3 and 4, and spikes into zone 5 when doing intervals or hitting a steep hill.
Now that I’m into the high intensity intervals, heart rate doesn’t really matter that much since watts are now my guide, but the HR zones will be important for when I’m riding without the power meter and only have HR as my general guide.







Winter is quickly approaching, which means it’s time to get back to the gym for some weight lifting. 
My next big event will be the 
amount of time off this. Back in March when I first started riding this, it took me about 20 minutes to do this puppy. This time it only took me about 14. I forgot to check as I got to the top part, but I think that’s about right! I’m pretty stocked. It’s good to feel this when you don’t think you’ve been making any riding progress.
I guess these things do wonders for losing weight and getting in shape…we shall see.







It looks a little like the image with the woman in it, although the machine I use allows you to adjust the tilt of the back from upright to lying down. I usually do both positions, and that is it for the squats on the legs. There’s a weight stack that makes adjusting weight really easy. However, I was wondering if using the other machines where you stack on the plate weights might be more challenging, so I went over and explored.
I used a Hack Squat today. Normally I lift about 250 doing this on the other machine. Turns out that when I use the Hack Squat, I can only do 200. I found doing this much harder than the other machine. I’ll definitely keep this one up.
I also used the Squat Press today. The difference between the machine I use and the one in the image is that the back of the seat is tilted further back. Normally I lift about 280 doing this on the other machine, and I was able to match the weight evenly here. However, it was more difficult to use this machine as well. I liked this machine as well and will probably continue to use it too.
The machine I used at the gym actually has me angled at around a 70-75 degree angle from the ground (rough estimate). I can stand such that it’s somewhat like pushing down hard on the pedals, while leaning forward in the neutral position on the handlebars of the road bike. I liked the positioning, and I was able to lift only 180 on this machine. It could have been because I was tired, as this was the very last thing I did before getting down to stretching and taking a shower. One other thing was that this causes a little pain in the upper back, so I’m not sure I’ll continue this one or not. If I do, I probably won’t lift as much.
