It depends. As a rule, you should give each muscle group at least 48 hours recovery time. It sometimes takes 72 hours. Gauge it depending on how you're feeling. Also realize that it can take as long as 7 days for a muscle to fully heal.

Overtraining is one of the most prevalent problems holding people back from their exercise goals.

Cardio is another story. You can do cardio pretty much daily, but even then it's good to have at least one or two days per week to allow for adequate recovery, especially if you do high intensity.

If you go pretty hardcore, it's a good practice to take a full week off of all exercise every 3 or 4 months. Press the reset button, so to speak.

Stress can wreak havoc on your body. Rest is underrated.
