Should I try to nail my workout after a night of crappy sleep?
A night or two of tossing and turning won’t throw you off too much, and you may feel more alert that day (and sleep better that night) if you run. If you’re chronically deprived, your body might shout “I give up!” – and you must listen. Running makes muscles, bones, and joints stronger only when those parts can regenerate after you’ve taxed them. Sleep is critical to that process. – Matthew Edlund, author of The Power of Rest
