Muscle fatigue

Ready

Your muscles are ready to tackle the next workout.

Recovering

Your muscles are still recovering from the last workout; if you use them now, your performance will be slightly lower than it would be tomorrow.

Fatigued

Your muscles are acutely fatigued from a recent workout; let them rest for a day or two to improve your next performance.

You can accelerate your recovery by sleeping enough (7-8 hours per night), having a balanced diet, and doing light activities that use other muscles.
