I knew slow jogging would improve my cardio fitness.

This morning, I went for my morning run as usual. Unfortunately, it was raining. It was only a light drizzle, so I decided to go for it.

Today I arrived at Nagai Park earlier than usual, so I ran three laps. I started out slow and then increased my speed. My heart rate doesn't go up anymore unless I go as fast as I can. I guess that's how much my cardio fitness has improved.

In order to accomplish this month's challenge, I need to earn my exercise time. Something that is OK for me, even with my hip injury, is slow jogging rather than long distance runs.

This is what it looked like when I went for a morning run, incorporating slow jogging while keeping the intensity at a fat-burning level!

It's already working.

You can tell what age I am by this graph.
At any rate, heart rate training has proven to be very effective.

Anyway, I need to improve my physical strength. If you improve your cardio fitness, you will be less tired. That's why you get stronger, right?

Well, even if you run as fast as you can, your cardio fitness will not improve that much. The calorie consumption is the same whether you run fast or at a normal speed.

I just want to get rid of the muffin top that gets in the way when I sit down.
