SORE MUSCLES = GOOD WORK
Don’t measure the effectiveness of a workout on how sore your muscles are the next day. Soreness is a direct result of inflammation, not training intensity. You can have the best session ever and feel relatively fresh the next day, just because your body is adapted to that style of training. The moral of the story? Measure progress against your goals, not whether you feel like you've gone ten rounds with Tyson or not.
