If you have a regular, weekly workout routine, meaning you take your appropriate rest days and don’t feel depressed or anxious, you may take the following advice.

When you have sore muscles from exercising, exercising the following day actually speeds up recovery. HOWEVER, not something like Insanity. Ensure that it is light exercises such as low intensity cardio and YOGA where stretches and controlled movement are good for muscle tightness and soreness, also encouraging oxygen and nutrient-rich blood to flow to the muscles, hence encouraging healing.
