Lots of stretching - I stretch all day long. I’m fortunate enough to work from home so I keep a yoga mat and foam roller in my home office, and use it periodically throughout the day, whether I am skating or not. Pilates really fucking helps - look at Brandon Turner! Dude keeps his instructor on speed dial and calls her up mid-sesh for advice.
For recovery, I love an epsom salt bath and I frequently use compression socks on my legs. There’s a lotta conflicting science on compression, but I find them soothing, so whateve - it works for me.
I agree with the no alcohol, sugar or grain bit, but I’m not too good at avoiding the latter two. These things absolutely and unequivocally promote inflammation, avoid them wherever you can.
I steer away from ibuprofen because it actually is pretty bad for liver and kidney function if you overdo it, so I’ve switched over to acetaminophen for the most part. Acetaminophen also helps with existential dread (no shit, this is real) so that’s a bonus.
