Working out with others can be a great motivational tactic. But if you choose to exercise with a partner or in a class, it can come with challenges too. More than once, I have had health coaching clients come to me feeling low because they are not able to do the same amount of exercise as their workout partners or others their age. It makes them feel depressed. With or without a chronic illness, reaching peak performance is about listening to your own body, responding appropriately, and investing long term in your health.
