There's already a forum called "Success Stories". When someone has success using WMM media, that's the right place to tell about it. If you listen to a WMM recording and have success with it, then post about it in that forum.
With that disclaimer out of the way, I'm inviting you to tell about successes specific to workouts, injuries, and goals met. I'll go first:
I changed my calf routine yesterday. In the middle of the night, I woke with a painful charlie horse. (if you're not in the USA, maybe you call it "jolly horse", "corky" or "dead leg".) That ain't the success.
I did the usual response - ate a banana, drank some water, and went back to sleep. About an hour later, I woke and realized I was experiencing the fuzzy-headedness of trance - awake but in trance.
As I laid there, I realized the calf muscles were spasming. And I realized: That's going to hurt in the morning.
Yep - my calves are sore this morning. But I'm stoked!
Without even trying, I use trance to sleep through delayed onset muscle soreness (DOMS). I consider that one hell of a success!
