Agree, and I'm someone who hates working out. Someone recently commented on exercising like "why would I choose to be miserable to 30 minutes a day", and I can honestly say it's because it makes you feel so much better the other 23 1/2 hours day. The smallest bit of cardio will make you more energetic, you don't get winded going up stairs, you can move easier, it's such a win. Yes it's miserable, but it is worth it.

It’s amazing that I’m older yet I have significantly less back pain just from working out semi regularly.

This is the way. I’m fitter, stronger, and look better in my mid 40s than I did for most of my 30s. I hurt less, I’m more capable, and I look at the future with a lot more interest and less trepidation.
