…as encouragement…I could barely slow jog around a 400m track for one lap when I first started running at age 66….I had to stop and walk after that slow one lap jog. I had never run a 5K distance in my entire life up until I started at age 66.

I started with a VO2 max of 35…just yesterday (I’ll be 70 in June) my VO2 max increased to 49.

Now I run three Zone 2 5K’s per week on a rubberized track and finish with two 0.25mile HIIT runs. Zone 2 running (70-75% of max heart rate) is totally sustainable and it’s absolutely incredible the long term impact.

IMHO diet and fasting help; but this aerobic protocol is proven via randomized clinical trial, in just 12 weeks effects appear (I’m 2.5 years into my dedicated protocol).

The problem is that it takes months and years and an absolute commitment to consistent implementation, which (unfortunately) many are just not willing (some truly unable) to do.

The most important thing, as one begins, is joint safety and running consistency, leaving one day of rest between aerobic running days. I wear Hoka Bondi 8’s, two pair of low cut socks and ALWAYS run on a rubberized track. I have never had a joint injury, or even a toe blister!

My average heart rate has dropped dramatically (see attachment) for my runs. This is because old mitochondria are destroyed and new (and many more) replace the old in both your heart muscle and leg muscles…I believe this same process slows (and eventually stops) cancer cell growth and progression.

All the best!
