An important fitness tip is to never exercise when you are sick. When you fall ill, your body needs all of its available resources for healing and recovering. Working out when sick will do more harm than good. So you have to have a break from working out until you feel better. To speed your recovery, eat properly and get sufficient sleep at night.
Limit your strength training fitness workout to three times a week to achieve the maximum benefits for your muscles. The real work for your body in strengthening muscles happens in the recovery time between workouts. Doing your workout routine for strength-training more than three times a week does not allow sufficient time for recovery and re-building.
