I think it’s important for anyone considering increasing their physical activity to have a recent physical exam by their primary care physician. I also recommend to keep in mind Rome was not built in day, so do not be overzealous. It’s fantastic to set goals and I recommend everyone do so, however we must allow her bodies to adapt to a new activity. Please take into consideration any previous injuries or areas of previous aches/pain. If you are using an instructor or a fitness coach do not hesitate to tell them issues that you have had in the past so that they can better understand what types of exercises will help you without causing pain. It’s important to slowly build up the repetitions and the intensity to build strength without causing injury. Muscle soreness as expected however joint pain is not. If your pain begins to limit your workouts then first and foremost you must reduce the intensity. If the pain does not respond to these adjustments then we recommend orthopedic evaluation.
