Sleep is possibly the most important time of the day. It is vital for recovery and helps ‘recharge your batteries’. Ultimately your body prepares itself for the next day. Getting too little sleep or too much sleep can effect your performance in just about everything. For example, after a day of exercise and weight training, sleeping and relaxing is essential for rebuilding muscle tissues. Also, as well as physically recovering, you also recover mentally. For example you are more alert after a good night’s sleep.
