Currently, my workout consists of (exclusively) high-intensity exercises (some sprinting HIIT, pullups, and more).
After a few attempts at research and help from this community, I've come to accept that I can't do this every day (until recently, I was sure there's no way I would actually want to exercise every day).
However, I'm hoping that there are some things I can do in between to further some goals - such as improving balance and flexibility.
From what I understand, there are many types of stretching, and it generally don't interfere with the recovery. As for balance, from what I understand it requires the use of core muscles, so I'm guessing... don't do it if you've worked out the core muscles the day before?
So, what can I do and what shouldn't I do in my rest days? (btw, I have gymnastic rings, so...)
