Running

I first tried upping cadence using 90 or 180 BPM music, but I could never get it to stick and my feet didn't catch the rhythm. A few years later I used a metronome and boy howdy did that work for sticking to the rhythm. I nailed my cadence for a couple of weeks until I started getting hip flexor pain. Recently I saw some research about how cadence isn't as important as people think lol. Now I'm back to feel and HR too.
