If you do not vary your workout routine your body will eventually run on cruise control, and you will experience a plateau.
Try new cardiovascular activities, or use free weights if you always use machines for strength training. Changes in your routine will surprise the body and force it to adapt, bringing you to new levels of fitness.
Please contact your Wellness Coach if feel you need a change. Some bodies adapt quicker to excercise than others, so they may not know a change is needed earlier than expected.
