Title says it all, but to elaborate...
Got into CrossFit because I was fast, energetic, and limber. Thought I'd do well running from exercise to exercise. And I did. But I wanted strength. And I started getting some too. But high reps lead to bad form, lead to injury, lead to frustration. Still enjoy an intense workout with varying exercises, but I do my own programming now.
Got to a point where I couldn't turn my head left and it became a problem when driving. Not to mention all the muscle tightness and constant popping. Started PT about a month ago and progressed well, should be cleared in another week or two. Not blaming CrossFit. I blame myself. I know better, I know how to say No Thanks.
Got cleared to begin training again, but was told to go light and focus on high reps for burns, rather than getting a pump. All this, and I turned 35 recently.
Sucks to get older and the body no longer tells you it hurts, but straight up tells you NO, you done fucked up. Glad it's nothing serious. But turning 35 means training a whole lot smarter.
