You are exactly 100% right... treadmill is as boring as it gets. I have 200 of my most favorite songs & music stored on my smart phone as MP3 files and I play it using a free app called Musicolet and I can listen to it during treadmill via Bluetooth so it is wireless. The phone is parked on a window nearby. I can choose via Musioclet which playlist I want to listen, such as Mozart or Pop or select a certain group such as Beetles or Abba, or a combination of any MP3 files.
The benefits of keeping this discipline of doing one mile in 23 minutes at 2 deg up-slope are so huge for my 80 year old body, I will be stupid to quit. I have no balance issues, no leg joint pains or cramps, the heart is working flawless, and I swear I could join a ballet class if I wanted to. Never ever expected to feel this athletic at 80 when I retired at age 57 with hip joint pain, racing heart, fainting spells at work, panic attacks in closed malls. All those issues are gone!
Thanks for the reply! I will try music. I have been watching the TV.
