I was always warned about muscle fatigue but had never experienced it before. I worked my butt off yesterday... I had 30 minutes of walking on the treadmill and eliptical, An hour with a personal trainer weight lifting and stretching and then 20 minutes on a treadmill doing interval training (2 minutes walking, 1 minute running). Throughout the workout, I drank around 1800ml (around 7 cups) water. I had a 45 minute drive home but during the way, I drank a whole bottle of water and then when I got home I had a smoothie (1 cup of frozen strawberries, 1 cup of almond milk). Dinner was a fajita (a lean steak around 6oz, a cup of orange and yellow peppers thinly cut and a half cup of corn) on a flax flat tortilla with 3 small microwaved potatoes- naked.
My husband thinks that I didn't have enough protein. But if that were true, wouldn't I feel really sore? I don't feel sore at all-- not even a bit stiff. Is this true muscle fatigue? What could I have done differently? Should I be worried?
