I'm sore as hell today. I kicked my own ass the other day with Tabatas and Olympic squats! Actually, this is a good thing. I wanted to start the New Year "feeling it" rather than rusting away. There is nothing wrong with being sore. I'll push myself a bit further with soreness levels than a typical client; however, if you are not sore once in a while, there is probably not much happening differently that would promote improvement rather than maintenance. Don't be afraid to push it a bit. If you need inspiration, come back to Jack LaLanne that says, "Better to wear out than to rust out!" Still pushing, Coach RJ!
