I am a data junkie so I ride with power on my bikes - road and track. And I think it is more fun to have metrics at the end of the ride and a power meter and software make it easy. I have over 10 years of power data with workouts that provide a nice history as reference and I can look back at rides and see how I may have changed.

I think intensity is important. Besides making ones muscles stronger and improving aerobic and anaerobic performance, it seems to impact epigenetics. According to some aging research, genes turn on and off as we age. https://www.whatisepigenetics.com/to...tics-exercise/ HIIT may improve genetic regulation keeping the good ones on and the bad ones off i.e. one stays genetically younger. In another aging theory, telomere shortening over time increases the effects of aging. https://www.statnews.com/2017/01/03/...lomere-effect/ I read her book - excellent. Telomeres are the ends of our DNA. Over time, the telomeres shorten until they disappear. Telomerase is produced by the body to maintain the integrity of the telomeres. HIIT / exercise, in general, may increases telomerase.

I am a trackie so I get a lot of intensity versus longer duration lower power efforts. In general, I do not do much z1/low z2 riding. The last two sessions with my coach, he killed us with motor work. The beauty of motor work is one cannot slow down and one gets used to speed over time. And with speed comes intensity and economy.

I like to do jumps, starts (seated and standing) plus accelerations to get my leg strength training on the bike. I use the gym as an adjunct to the on the bike strength training.
