If you’re just undergoing a period of increased time commitments at work or with family, using a shortened exercise routine can help minimize your losses. Even one session a week will help you keep most of what you’ve gained. Other options are to use shorter but more intense interval training sessions, or breaking up your activity into multiple short chunks during the day. If your layoff was longer, it may take just as long to retrain as it did to make the gains initially. If you’re having those aches and pains due to inactivity or need help designing a safe program to either maintain your fitness or gain it back after a layoff, your physical therapist can help. Injury and illness are other common reasons for detraining. Your PT can not only help you recover faster, but they can also find activities to maintain your fitness while safely working around an injury or illness.
