Healthy training plans also include purposeful recovery. For me, this means a monthly massage. I treat it like a doctors appointment or a scheduled long run (but better because there’s chocolate and I get to almost nap).
More rigorous training requires more recovery. Most people cannot afford massages regularly but there are a few tricks to extend the life of each massage.
Epsom salt baths are a must for sore muscles (sometimes to even relax enough to sleep after a race). I like to add in a few drops of essential oils like eucalyptus or lavender.
Foam rolling or using a massage stick after every workout also helps your body heal. Making it a pattern and mandatory is the hard point. If you want to run again and without injury, you must make time for recovery.
