My legs do anyways and why do you ask. Diligence that is why. If I run longer than a 10k and most runs these days I am then I make sure to do a cool down walk right after I run I consume something that is protein heavy to help with recovery and when I get home after i shower I roll and then I slap on full leg compression sleeves that Danielle lovingly got me for Father's Day.
Doing these simple things have helped reduce any stiffness or aches which I used to be prone to get.
BTW my feet feel great today as if I didn't run at all that's another great testimony for the Connect.
