I often hear "listen to your body" trotted out. What does it actually mean ? - mine never shouts at me "don't go to the gym" or "don't ride your bike". When I see a decent hill coming In often wish it wasn't there - should I listen to my body and get off and walk ?
It's quite difficult to explain this to someone who appears to be unaware of his/her body. I'm going to try. I had a heart attack ten years ago, stent fitted, Aspirin and statins for life. Some similarities. I've also had an aneurysm, burst blood vessel, in the brain. I'm 70.
Today with respect to my heart and head I can do whatever I wish but in the six months recovery following my HR I could tell if I pushed to hard. My initial recuperation was walking, if I went to hard, too far I came home exhausted. My body was telling me to back off, rest for a day or two and go again but easier and build towards the effort which exhausted me. During recovery from my aneurysm what I today consider nipping out for 25 minute walk would utterly exhaust me.
I'm currently recovering from a serious RTC. I was hit by a tractor at 35mph. I'm 95% fixed but still experience shoulder and knee issues. On Saturday I rode 52 miles with my club, held the fastest pace and climbed more than on any previous rides since the RTC. On my return home everything was fine. On Sunday my knee was swollen so instead of the planned weights work out I settled for gentle stretching, a 40 minute walk and 30 minutes with an ice pack. This morning the swelling has reduced significantly. Instead of today's planned ride, I'll do a gentle spin class and ride again on Wednesday.
I have a friend who used to "ride off" any form of illness, especially chest infections, or injury without allowing his body to rest. He wrecked his breathing and back, no longer rides and walks with a stick. We watched him do it for years.
I could give you several other examples based on personal experience. Rest is as important to the body as exercise. It's during the rest period the body rebuilds itself. Push an injury or illness too hard during recovery and one risks further damage in the long-term.
In terms of rest I stretch for 25 minutes every day and exercise five days a week, usually 3 on, 1 off, 2 on, 1 off.
This is listening to the body, I'm surprised you've never experienced similar.
