So, we have looked at the right number of repetitions, the correct amount of sets, the right sort of exercises, but there’s also one less connected yet obvious factor: are you getting enough sleep? Sleep is essential for toning up, as your body repairs itself when you are asleep. So if you are generally overtired and lacking in the beauty stuff try to get a bit more. Remember that in training you are damaging yourself, the improvements only come in the recovery phase. Try to get 7-8 hours of sleep a night, and to go to bed reasonably early.
