I think I'm on the verge of overtraining.
During Legs & Back this morning, my left leg kept wobbling during relatively easy lunge exercises (e.g., Sneaky Lunges, Side Lunges, etc.). After a few weeks of trying to cram Insanity workouts and barefoot running into an already-demanding P90X schedule, something's bound to give, and I don't want it to be my knees. I'd hoped to go running yesterday, but I got busy at work, and I think I'm going to rest my legs for the remainder of today, too. A few days of R&R can't hurt, right?
